Lots of snapraid errors

  • Hi,


    I may have done something stupid. A few days ago, my OMV NAS was unresponsive (no Web UI, no ssh, no Samba), and so I rebooted it after a few minutes (later I found some mails about exceeded resource limits, so that probably was the reason).


    Now I did the first "snapraid sync" since the reboot, and I get lots of errors:


    Code
    Data error in file '/srv/dev-disk-by-label-Data4/file1.mkv' at position '1064', diff bits 73/128
    Data error in file '/srv/dev-disk-by-label-Data3/file2.mkv' at position '232', diff bits 69/128
    Data error in parity 'parity' at position '7632915', diff bits 1/2097152
    Data error in parity 'parity' at position '7634385', diff bits 1/2097152
    Data error in parity 'parity' at position '7635226', diff bits 1/2097152
    Data error in parity 'parity' at position '7635622', diff bits 2/2097152
    Data error in parity 'parity' at position '7638365', diff bits 1/2097152


    and even


    Code
    Verifying /srv/dev-disk-by-label-Data1/snapraid.content...
    Verifying /srv/dev-disk-by-label-Data2/snapraid.content...
    Verifying /srv/dev-disk-by-label-Data3/snapraid.content...
    Verifying /srv/dev-disk-by-label-Data4/snapraid.content...
    DANGER! Wrong file CRC in '/srv/dev-disk-by-label-Data3/snapraid.content.tmp'
    Verified /srv/dev-disk-by-label-Data4/snapraid.content in 10 seconds
    Verified /srv/dev-disk-by-label-Data1/snapraid.content in 10 seconds
    Verified /srv/dev-disk-by-label-Data2/snapraid.content in 17 seconds


    Since the errors are on different disks and the disks are all healthy according to the SMART info, my guess is the problem is with the snapraid data (maybe I intererrupted the "snapraid sync"?).


    fsck also looks good:



    Now my questions are: Am I right in thinking the data is OK, it's just the parity that's fucked up? If so, how do I fix it?
