Backups, replications are running just fine, queue info is good.

Would reboot of appliance help ?

... Thanks

    I think you didn't get a quick response because there wasn't much to go on - i.e. no appliance logs (e.g. storaged, spoold), no output from any of the crcontrol query commands, no other description of symptoms, no nbdevquery of storage server and pool and volume, version not specified.  You found the MegaCli64 command to check BBU, but did you also use MegaCli64 to check parity group, disks, adapters - and what about checking VxVM too?  Do come back with more info, and someone might try to help more quickly next time.

    1. manage>storage>scan

    Storage> scan
    - [Info] The scan operation can take up to 15 minutes to complete.
    - [Info] Refreshing the storage devices...
    - [Info] Succeeded.

    2. monitor

    Storage> monitor
    - [Info] Performing sanity check on disks and partitions... (5 mins approx)
    - [Warning] The 'MSDP' partition '0' is not mounted...
    - [Info] Mounting the 'MSDP' partition '0'...
    - [Error] Failed to mount the 'MSDP' partition '0'. A full file system check (fsck) needs to be performed on this partition.

    3.comment out entry in fstab for 'pdvol', reboot make sure that 'pdvol' is not mounted, run:

    fsck -t vxfs /dev/vx/dsk/nbuapp/pdvol –y

    fsck from util-linux-ng 2.16
    pass0 - checking structural files
    pass1 - checking inode sanity and blocks
    pass2 - checking directory linkage
    pass3 - checking reference counts
    pass4 - checking resource maps
    au 184321 summary incorrect - fix? y

    ...

    4. rebooted appliance (mounted pdvol after it corrected itself) -  didn't have to but just want to be clean

    Glad you got it fixed.

    Are you able/willing to show the commands and output used to demonstrate/detect that it was a corrupted VxFS file system?

    Can I ask, how did you go about validating that the higher layer constructs of application folder structures and files and data (i.e. MSDP) had themselves not been corrupted by the VxFS corruption?

    Thanks.

    It was a corrapted vxfs file_system, unmounted, and run a full fsck.

    rebooted appliance after and we are back into a normal usage numbers.

    still the same:

    Reserved space                   : 4879383494656 bytes (4.44TB)
    Reserved space percentage        : 4.0%

    I was hoping that 'forum' might have a 'quicker' response, I'll open call with support see what they have to say.

    thx

    Doesn't look good.  It shouldn't need a reboot, as you've just cold booted it following a BBU replacement.  If it's still showing as zero, might be best to place a call with support.

    What's ths current status?

    What version of appliance?  You might be on an older version which used to take some time performing checks before the 'disk pool' would come online and 'up', and then be ready for backups/restores.
