Intl: +1 925 924 9500. Those resource forks are essentially additional file data that the Mac has to go enumerate and read before displaying it to the user. What are the ports required to open between client network and Isilon network on Firewall ? 9. Is there a way to monitor the statistics so we can trend and alert on them if they get to an unacceptable limit? When the client accesses files and permission checking is required in Step 3 and beyond, there is no need to talk to the DC to lookup group memberships. We look forward to an interesting and informative discussion! But Ps with the flag to show threads does not look so bad: root  3311  0.0   0.1 130836 15688  ?? Ask the Expert: SMB Protocol on an Isilon Cluster, Re: Ask the Expert: SMB Protocol on an Isilon Cluster, Re: Re: Ask the Expert: SMB Protocol on an Isilon Cluster. Pappu Shakib on Pure Storage data reduction re … Pappu Shakib on Dell’s MG on Storage Performance Benchmarki… katrinkunze on … Support Us By Shopping Your Own Favorite Products This video describes how to create SMB share in isilon command line. Typically that's not an ideal workflow for SMB. These ports can be changed during or after installation. I've done that because we have up to a thousand client connections per node 0 that is just a lot to dig through. SMB Throughput (Bytes per Second) The total throughput for SMB (SMB1 & SMB2) operations. To limit the size of this post, I am going to talk about the Freebsd and isi statistic stats that I look at when troubleshooting SMB Performance issues. The down side is, the first place I would look is the client side trace to figure out if it is failing against the DFS server or the Isilon cluster. People used to set it to around 400 for SMB1 but if you do that for SMB2, you will lose compounded commands so it is best to capture the entire frame. Once the client tears down the SMB session, (for example a Session Logoff or TCP,RST) the client will have to go back through Step 2 before it can move on to Step 3 and beyond.

Tcpdump cannot flush to disk fast enough so you end up with dropped frames making the trace unreliable. The following ports connect the Converged System to the Converged Technology Extension for Isilon storage cabinet: 10 GbE uplink ports — Eight cross connections are used by default (which is also the maximum) for each switch. When the user first logs in they get a generic "Access Denied". This counter can be indicative of an issue but will not tell you directly where the problem is. Choose the API verson that is supported on the Isilon cluster. We have this documented in KB 89045. In my experience with the Mac, my goal is to get metadata retrieval latencies down to minimums. In computer networking, Server Message Block (SMB), one version of which was also known as Common Internet File System (CIFS / s ɪ f s /), is a communication protocol for providing shared access to files, printers, and serial ports between nodes on a network. Note: when I say "Windows networked drives", I'm not entirely sure whether I'm referring to SMB or CIFS, and I'm not entirely clear on the difference between the two protocols. At this point, it's far to early for me to say if something like the SMB2 support in OS X 10.9 is going to make much of a difference, although it is something I'm starting to test with for an update to the Mac guide. I am glad you asked I have a very good step by step action plan that you can collect in order for us to resolve the issue. We have been told many time "oh it's fixed in the next version OneFS", we upgrade only to be disappointed again because the issue continues. Tcpdump is native to freebsd and is not cluster aware, therefor you have to isi_for_array when you want to run it across multiple nodes. -I hope this helps. By default tcpdump will truncate frames to 96 bytes. -- Reboot the client and generate the error, -- Apply wireshark filter smb2.nt_status != 0 and figure out what frame the Access Denied is coming in, -- Determine if it is the DFS Server or the Isilon Cluster throwing the error, -- Follow the TCP Stream (right click option on the problem frame) and go to the beginning to locate the Session Setup to determine what User account was actually being used, One issue i've ran into with isi_netlogger (this may be caused by tcpdump havn't investigated) is that it dies after very long captures... (hours). Hope this helps. It may take 1 second for some other client to trigger a change, it make take 2 days if nothing changes in the directory while explorer is open. As the document describes, retrieving metadata faster from the Isilon is the best way to get the Finder to display objects more quickly.

The SMB2 Reads that are latent are a victim of the disks which in this case is spindle bound due to other contention. But, you're still at the mercy of network latency, as I mentioned above. Lets say that /ifs/tmp was a NFS export and you explicitly wanted those Mode Bit Rights set based due to Unix client application requirements. So the above performance is as expected? This discussion will focus on supporting the SMB Protocol on an Isilon Cluster, including: Peter Abromitis has been in support for over 8 years and is specialized in the Windows Protocol area. We are on The app writes a temporary file to an smb share on Isilon. 8. Entered the details from the account you created in step 1. SMB Security Guard Ransomware Defender SMB TCP 445 SMB2 only: TCP: appliance → Isilon/PowerScale : Ransomware Defender Since you have GPO in play as well, that initial connection against the cluster may be under the Clients Machine Context rather than the Clients User Context which means it may be coming in as an anonymous user which could be causing the Access Denied. And, making those changes to the client require that all clients get the change. That can be useful in cases where two graphics editors are watching the same directory, and one needs to know when the other has updated a file, or added a color label. 10. Thus, there is risk associated with using "Apply Windows Default ACLs" with a currently existing directory. Pete is a member of Everyone and gets Read at the share which overrides the File System Permission of Everyone Read/Write. 2. English EN; Português PT; Espanol ES; 简体中文 CN; Français FR; Deutsch DE; 日本語 JA; 한국어 KO; Italiano IT; Nederland NL I have created the share as oraprod001_share after checking the ONEfs 7.1 user guide but when am trying to access the SMB / CIFS share - am unable to access it. Then it tries to access the temporary file for some processing and gets a generic error saying "file not found" inside the application. Support . The first thing I like to do is connect to Start -> Run ->  \\cluster (do not add a share to the end). Displays a summary of active, completed, and failed jobs. The problem I am working on now is an odd one. --------------------------------------------. Verify the user is either directly in or is a group member of an entry in files system permission in step 4. When you add DFS in the mix, the client has to: -- Perform Step 1-3 against the DFS Server, -- Get redirected to the cluster via a dfs referral, -- Go through Steps 1-3 against the cluster, -- Finally connect to the path on the cluster. -- If this works, you can almost always get away with filtering on just the client ip from a cluster side trace, because the problem is outside of authentication. At that point it becomes a question of what are you trying to accomplish with the trace. How can I find out the currently used smb verison at a cluster? Node. Below is a table of Isilon port usage and the OneFS services that use them. 2.) ie they are not going through a firewall or wan accelerator. -- If a user connects to a cluster and it uses Kerberos: -- If the user connected earlier and we already have the SID from the user token resolved to a username in our SID Cache, it will work. Collect ls -led and ls -lend ouptput of the paths (I am truncating the otuput), isi-ess-east-1# ls -led /ifs/data/itgroup, drwxrwxrwx +  2 root  wheel  0 Jul 15 09:33 /ifs/data/itgroup, CONTROL:dacl_auto_inherited,sacl_auto_inherited,dacl_protected, 1: creator_owner allow dir_gen_all,object_inherit,container_inherit,inherit_only, 2: group:Administrators allow dir_gen_all,object_inherit,container_inherit, 3: everyone allow dir_gen_read,dir_gen_write,dir_gen_execute,std_delete,object_inherit,container_inherit << Note this gives the Everyone Group Write Permission, 4: group:Users allow dir_gen_all,object_inherit,container_inherit. What has changed? Since we have established that SMB2 is latent and it appears to be impacting reads, the next place to look would be disk: isi statistics drive --nodes=all --interval 5 --repeat 12 --degraded, isi-ess-east-1# isi statistics drive --nodes=all --interval 5 --repeat 12 --degraded, Drive    Type OpsIn BytesIn SizeIn OpsOut BytesOut SizeOut TimeAvg Slow TimeInQ Queued  Busy  Used Inodes, LNN:bay           N/s     B/s      B    N/s      B/s       B      ms  N/s      ms            %     %, 1:1     SATA  72.2    2.3M    32K  129.8     2.2M     17K     0.6  0.0    58.8    8.7  93.5 100.0   3.4M, 1:2     SATA  56.8    1.9M    34K  157.4     2.9M     18K     0.4  0.0   208.8   31.0  65.1 100.0   3.0M, 1:3     SATA  86.0    2.4M    28K   88.6     1.6M     18K     0.4  0.0   133.1   22.0  84.3 100.0   3.0M, 1:4     SATA  54.0    2.1M    38K  118.6     2.3M     20K     0.4  0.0    52.3   11.1  72.7 100.0   2.5M, 1:5     SATA  74.0    2.5M    34K  106.6     2.1M     20K     0.4  0.0    52.3    9.3  57.3 100.0   3.3M, 1:6     SATA  66.2    2.5M    38K  100.6     2.0M     20K     0.4  0.0    53.3    8.4  86.1 100.0   3.2M, 1:7     SATA  47.4    1.6M    34K   94.2     1.8M     20K     0.4  0.0    46.4    7.8  49.7 100.0   3.3M, 1:8     SATA  65.4    2.3M    35K  145.8     2.5M     17K     0.4  0.0    37.8    7.5  75.1 100.0   3.4M, 1:9     SATA  51.2    2.1M    40K  119.2     2.1M     18K     0.4  0.0    35.8    6.7  56.3 100.0   2.5M, 1:10    SATA  62.0    2.0M    32K  101.2     2.2M     22K     0.4  0.0    33.8    6.0  56.5 100.0   3.4M, 1:11    SATA 126.6    3.2M    25K   76.2     1.4M     18K     0.3  0.0   201.1   33.5 100.0 100.0   3.0M, 1:12    SATA  66.2    2.0M    31K  117.8     1.9M     16K     0.3  0.0   106.9   21.3  85.1 100.0   3.0M, 3:1     SATA  40.0    1.4M    36K  107.4     1.8M     17K     0.3  0.0    89.2   17.1  37.5 100.0   2.9M, 3:2     SATA  54.2    1.8M    33K  113.4     1.9M     17K     0.3  0.0    68.4   14.7  60.7 100.0   3.0M, 3:3     SATA  56.0    2.1M    38K  112.2     2.0M     17K     0.3  0.0    65.6   14.4  40.7 100.0   3.3M, 3:4     SATA  73.8    2.3M    32K  113.6     2.0M     17K     0.3  0.0   114.3   13.9  54.5 100.0   2.3M, 3:5     SATA  66.8    2.1M    32K  106.8     1.9M     18K     0.3  0.0    74.0   11.2  50.5 100.0   3.5M, 3:6     SATA  78.4    2.7M    34K  138.2     2.2M     16K     0.3  0.0    75.8   11.1  82.1 100.0   3.4M, 3:7     SATA  58.4    2.2M    38K  127.8     2.1M     16K     0.3  0.0    77.1   11.0  54.7 100.0   3.4M, 3:8     SATA  54.6    2.0M    37K   90.4     1.4M     16K     0.3  0.0    75.1   10.7  39.9 100.0   3.0M, 3:9     SATA  56.2    2.0M    36K  139.4     2.5M     18K     0.3  0.0    59.9   10.4  61.5 100.0   3.3M, 3:10    SATA  59.0    1.9M    33K  110.2     1.8M     16K     0.3  0.0    55.2   10.2  49.3 100.0   3.3M, 3:11    SATA  55.0    2.0M    37K  122.2     1.9M     16K     0.3  0.0    59.4    9.3  46.1 100.0   2.5M, 3:12    SATA  51.4    1.8M    35K  102.0     2.1M     20K     0.3  0.0    50.3    9.1  47.7 100.0   3.3M, 4:1     SATA  52.2    1.8M    34K  117.2     2.1M     18K     0.3  0.0    53.5    8.8  51.7 100.0   2.8M, 4:2     SATA  58.8    2.1M    35K  107.2     2.0M     18K     0.3  0.0    47.8    8.7  48.9 100.0   3.3M, 4:3     SATA  64.8    2.3M    35K  120.6     2.2M     18K     0.3  0.0    44.2    8.6  57.1 100.0   3.4M, 4:4     SATA  50.8    1.8M    35K   77.8     1.7M     22K     0.3  0.0    53.8    8.6  38.1 100.0   2.7M, 4:5     SATA  58.4    2.2M    38K  135.6     2.4M     18K     0.3  0.0    51.8    8.4  48.9 100.0   3.4M, 4:6     SATA  65.0    2.4M    37K  108.8     2.1M     19K     0.3  0.0    55.9    8.3  55.3 100.0   3.3M, 4:7     SATA  57.0    2.1M    37K  106.8     2.2M     21K     0.3  0.0    46.9    8.2  49.5 100.0   3.3M, 4:8     SATA  58.8    2.0M    34K  149.0     2.7M     18K     0.3  0.0    46.2    8.2  58.7 100.0   3.3M, 4:9     SATA  53.2    1.8M    33K  124.0     2.3M     19K     0.3  0.0    45.0    8.2  56.3 100.0   3.4M, 4:10    SATA  76.0    2.3M    30K  103.8     1.9M     18K     0.3  0.0    44.8    8.0  60.1 100.0   3.3M, 4:11    SATA  60.2    2.1M    35K  116.0     1.9M     17K     0.3  0.0    42.6    7.9  65.5 100.0   3.1M, 4:12    SATA  59.0    2.1M    35K  100.2     1.8M     18K     0.3  0.0    48.2    7.8  41.3 100.0   2.4M. This option is often mis-understood so I am glad you asked. Cause: There was a 32 work item queue introduced via a scheduler for handing SMB traffic in OneFS … When it comes to performance, 99% of the time there is no silver bullet to fix the issue. This leads us to our next logical counter which breaks down the protocol by type. An associated service running on the protocol specific port translates the commands/data into the appropriate action onto the underlying file system. source and destination plus what would happen if it was closed. I can send you an example script if you would like. You could compare your smb sessions to the raw netstat output (also you have to remember that these counters are going to be a per node basis): For example when I look node 1 of my cluster, I see that I have two smb sessions that have been idle for a long time: Username                :ISI-ESS-EAST\sli, Username                :ISI-ESS-EAST\pete, tcp4       0      0     ESTABLISHED, tcp4       0      0   ESTABLISHED, tcp4       0      0 *.445                  *. This might be a pretty basic question but I haven't yet found a good explanation for this. Regardless of whether you write the data with SMB or NFS, you can analyze it with a Hadoop compute cluster through HDFS. (we are not upgrading to 7.x). We do not have an equivalent to smbd -V.  For smbstatus you can run the following: Is there a way to find out which share is connected to what file server(s). It is specific to an application,  when we monitor and alert on... but by the time the error is generated inside the application it's too late.. The only way to fix it is to killall -9  lsassd . HTTPS over port 8080: TCP TLS 1.2 : Eyeglass appliance → Isilon/PowerScale cluster: All: REST API is authenticated using the service account created here. This is essentially identical to SMB over TCP/IP on port 139 except for some minor details at the network level. This topic provides an overview of the technology and the new functionality in Windows Server 2019, including using a USB drive connected to a router as a file share witness. After you have proven that you can connect to the cluster without any issues, I collect the following data to determine why permission is being denied: 1.) Your email address will not be published. Idle connections mean that the TCP session is active but there was no SMB request sent during the time the stat was collected. Phone Get Quote . Map a drive direct to Isilon via Group Policy,  and it works. Is there a way to drop the inactive connections without affecting the active connections? OneFS – The operating system of an Isilon cluster. SMB continuous availability PowerScale OneFS 8.0 and later SMB continuous availability and witnessSMB continuous availability and witness SMB encryption PowerScale OneFS 8.1.1 and later SMB encryption 1.2 Networking In a scale-out NAS environment, the overall network architecture must be configured to maximize the user experience. Isilon product name. I will however provide some general pointers to troubleshooting a permission problem. Next up is the random disconnect when using a SmartConnect zone name for accessing the WebUI. The length of time in seconds that Cisco UCS Director will wait to establish a connection to the Isilon cluster before timing out. API Version drop-down list. If you see "stale" connections, it really means they are idle and there is an active tcp session associated with it that is being kept alive or has not timed out yet due to inactivity. Serial number of this node. When I start looking to see if SMB is latent, I prefer the following stat over the connection count: isi statistics protocol --nodes=all --protocols=smb1,smb2 --total --interval 5 --repeat 12 --degraded, isi-ess-east-1# isi statistics protocol --nodes=all --protocols=smb1,smb2 --total --interval 5 --repeat 12 --degraded, Ops  In Out TimeAvg TimeStdDev Node Proto Class Op, 10.1  1.2K   10K  2081.6     4037.0    1  smb1     *  *, 706.4  140K  129K  180817.1   2589.5    1  smb2     *  *, 0.4  30.3  33.5  5085.5     5895.1    3  smb1     *  *, 812.7   18K  8.2K  151469.2   6842.4    3  smb2     *  *, 0.4  30.4  33.6  1542.0     1074.8    4  smb1     *  *, 71.6   23K   13K  25407.8      714.0   4  smb2     *  *. The default is API version 1. Setting SMB Shares in OneFS. OneFS 7.1.1. will be the initial release of OneFS to allow MMC management so the use of this tool would require the latest OneFS version.

When we perform a simple copy test we see the read from cluster is 6 MB/Second and write to cluster is 12 MB/Second. Wall Clock or something that can accurately measure time? Those backups were being written to a 5 node Isilon cluster. Therefore each node can be considered a self contained unit. Historical Counters - Yes! The 5 minutes is tunable: isi auth config modify --check-online-interval=, isi auth ads modify --check-online-interval=. We map a 2nd drive via cli or gui to the same path Group Policy maps to - and it works fine. My experience with the Mac has shown that changing change notification from All to norecurse solves a strange behavior in the Finder where it'll occasionally flip from one subdirectory all the way back to the root of the share (without user intervention). Start the packet traces (You will have to modify this command for the specific interfaces in your cluster (ie lagg0 may be em0) and you will also need to put your DC IPs in, isi_for_array 'tcpdump -s 0 -i lagg0 -w /ifs/data/Isilon_Support/DomainOfflineIssue/`hostname`.$(date +%m%d%Y_%H%M%S).lagg0.pcap -- host or host &', isi_for_array 'tcpdump -s 0 -i lagg1 -w /ifs/data/Isilon_Support/DomainOfflineIssue/`hostname`.$(date +%m%d%Y_%H%M%S).lagg1.pcap -- host or host &', isi_for_array -s 'isi auth log-level --set=debug', 4.) There is not a current native means to duplicate those shares. mount, NLM/NSM), each of them needs TCP/UDP ports which would not be the well-known ports listening on the network. When looking to run a tcp dump to troubleshoot an SMB collection between a client and an Isilon cluster I have always limited my collection to a specific client (ie tcpdump -s 0 -i host ". Authenticatio uses Isilon session authentiation method. The Isilon cluster also supports a form of the web-based Distributed Authoring and Versioning (WebDAV) protocol that enables users to modify and manage files on remote web servers. *Interesting note, in all the years I have been in support, nothing has ever changed. Hi Admins, I have a isilon ONEfs setup with 2 Nodes.Am implementing a test SMB share access for a folder under /ifs/data/oraprod001. Please feel free to continue the conversation (note that it will not be formally moderated by Pete after today) or start a new thread in the Isilon Support Forum to dicuss other topics. The lsassd service will stay in an Offline state for 5 Minutes at which point it will perform a new Domain Controller discovery and select a new DC. SMB/CIFS – The Server Message Block (SMB) Protocol is a network file-sharing protocol; it supersedes Common Internet File System (CIFS), an earlier protocol.
