Snapraid missing files that exist

  • Hello,
    I am having an issue w/ snapraid. i have added in 5 more disk to my pool (it was AUFS, but when i added in the new disk i changed over to mergerFS) the pool appears to be work fine. But when snapraid cron job runs i get an email.
    WARNING! All the files previously present in disk '5tb01a3' at dir '/media/d60d3cc6-162e-46b3-9e9a-0e9019dc6aaa/'
    are now missing or rewritten!
    This could happen when restoring a disk with a backup
    program that is not setting correctly the timestamps.
    If you want to 'sync' anyway, use 'snapraid --force-empty sync'.
    when ssh into the machine and check that drive everything is there, and i am still able to access the files that would be on that drive via mergerfs file share.
    I know i should not have changed two things when i did my upgrade (adding disk and changing drive pool method).
    Thanks you for any information.

  • Are you adding the mergerfs pool to snapraid or the individual disks in the mergerfs pool to snapraid?

  • edited.
    The 5tb01a3 is not having issues as far as i can tell I can access all the files on it via the MergerFS share though. I will check the SMART logs on 5tb01a3

  • minor update. I ran "snapraid -E sync" then "snapraid touch" in an SSH section and that appears to have fixed the issue and errors (i hope)
