  • Hello. After reboot of the installation complex. Has ceased to mount one of the volume:
    Xsanadmin (utro_02) > fsmlist
    FSM Processes on tp-mdc.tp

    utro[0]
    State: STOPPED (generated too many core files) 2017-05-19 17:03:33
    Last Admin: START 2017-05-19 17:03:02
    Last Termination: signal(6)+core 2017-05-19 17:03:33
    Launches 4, core dumps 4, flags

    utro_02[0] port 59966, pid 68612
    State: REGISTERED (no substate) 2017-05-19 11:28:14
    Launches 1, core dumps 0, flags

    When I run through the console, the volume starts but after a while it stops again and in the logs the following errors:
    20.05.17 08:47:35,885 fsm[24293]: Xsan FSS ‘utro[0]’: PANIC: /System/Library/Filesystems/acfs.fs/Contents/bin/fsm ” The stripe group “MetadataAndJournal” size is 4194240, expected 3686390.

    I tried to run the cvfsck utility, but the error is all inherently flawed:
    bash-3.2# cvfsck -wn utro
    Checked Build disabled – default.
    *Fatal*: Stripe group ‘MetadataAndJournal’ size has changed from 4194294 blocks to 3686390 blocks
    *Warning*: Error initializing shared metadata stripe group ‘MetadataAndJournal’ – Invalid argument

    *Critical*: File System Read-Only Check finished – with errors.

    cvfsck total elapsed time: 0.07 seconds total
    bash-3.2#

    Whether prompt it is possible as that to restore volume or at least as that to restore the data? I will be very grateful for any advice and help…
