  • Reply to: New Xsan3 Install/Config Help!!   2 days 8 hours ago

    After spending more time troubleshooting, I have found that the cause of this issue was that I had a proxy configured and forgotten to input my local domain in the exclusion list. Disabled the proxy problem resolved!

    Mmmmmhhh.

    Shutting down the Xsan and full restart after the SetFile command solved the issue.
    Curious that the previous times i didn't needed to do it.

    Anyway, this is solved.

    no i didn't make the arrays via script but through web gui. Will try with script as well. Thanks

    So in short, i add the second volume, i create the new profile of the Xsan and install it on the clients, mounting both volumes, then i unmount manually the volume i want on the single client.

    Understood correctly?

    Have you used the script provided by Apple to configure it?
    https://support.apple.com/it-it/HT200273

    Have you perhaps tried to connect it in DAS mode to a workstation with 2x fibre cable, doing a Raid 50 of the two Raid 5 LUNs anche check the performance? (in dual channel 4G you should obtain around 600 MB/s)

    My vtrak model is E610f. Two years ago I've changed the complete arrays and made 1 raid1 of 2hdds, 2x.raid5 of 6 hdds with 2 spares. Tried the same settings this time too but it didn't work so I tried different. Vtrak is fully updated and arrays are well configured. Sent the system report of vtrak to promise week ago and they confirmed that hardware and configurations are good. For controllers I've dedicated ctrl1 for metadata and one data luns and 2 for 1 data lun. Yesterday night again my volume crashed so now I am again going to make a volume today with metadata in different vtrak and data arrays in different arrays.

    Hi.

    Hi.
    One more question.
    You said you rebuilt the xsan 2 years ago changing the HDD, but you changed the HDD in an old backplane, or you changed the array completely? You spoke about Promise. What model is it? Is the front of a silver color, or the old dark grey?
    Also, you said your r/w results are 50/200 which is extremely low (on a single fc 4g cable you should obtain at least 350 in both r/w).

    Have you checked the battery status of your array?
    Have you tried changing the Lun configuration from 4x 3hdd raid 5 to 2x 6hdd raid 5?
    Are you in a "read ahead" and "write cache" status?
    Is the lun affinity to the controllers (I hope it's a dual controllers) correct, splitting the load on both?
    You should check it in a DAS configuration if you can.
    Let me know about it.

    and the system logs of both mdcs

    Hi trevor,
    I've attached mdcs summary.

  • Reply to: xsan volume interrupted while deleting data or moving data   3 weeks 6 days ago

    need logs. system and summary.

  • Reply to: xsan volume interrupted while deleting data or moving data   3 weeks 6 days ago

    I think its a network issue.
    Following is the timeline how my SAN is crashing:
    1) DAY1: SAN created from scratch (including RAID building) and tested on mdcs only
    2) DAY2: Added 1 client on fibre only and starting moving data on SAN
    3) DAY3: Deleted the data from SAN placed in 24 hours, after deletion SAN remains perfectly fine
    4) DAY4: Added other 11 fibre clients on SAN and users started using it, shared to 8 ethernet clients as well via SMB/AFP/FTP.
    5) DAY5: Volume interrupted while deleting/moving data from SAN. MDCs don't provide remote screen sharing and are in abnormal situation. Even when i directly connects to MDC and try anything on it (unmount, force failover etc) nothing happens, not even mdc restarts itself. Have to give the MDCs a power recycle and after that they starts the SAN Volume.

    Now i think network is not stable but my networking incharge is requiring a prove. What logs should i provide him to give him a prove :(

  • Reply to: xsan volume interrupted while deleting data or moving data   4 weeks 8 hours ago

    Yes it did stop the volume first than sudo cvfsck -j Volumename
    sudo cvfsck -nv Volumename
    sudo cvfsck -wv Volumename

    and did until it says clean but the above mentioned error remains their.
    What do think is it the problem of hardware or configuration?

    hmmm have you tried to repair using cvfsck -wv VOLNAME

    or does it go fatal there too. remember volume need to be stopped.

    also run cvfsck -j before doing the checks.
