Strange issue. I lost multiple folders after power outage

    Hi All


    I hope that you guys can help.


    I have a small setup with a RP4 with 2*4TB USB disk connected, the 2 disk are created as a singe disk via Union Filesystems, and because one disk are full, all new files are written to disk 2.

    Everything have been running fine, but after a power outage last night, I've seems to have lost multiple folders that have been created after end of July.


    I've disconnected disk 2, and did a fsck -v on the disk on a Linux PC, just to make sure that there didn't were any issues with the filesystem. It did find some issue, but I don't think they are related to this issue.


    I think it's strange, that it seems like all files that have been added after a given point is gone, all other files are fine. Have you seen this kind of issue before, could it be an access issue to the file, so I can't see them?


    Best regards

    If you are looking in the mergerfs mount folder, try looking on the actual disk that the files were written to instead.

    A backup strategy is worthless unless you have a verified to work by testing restore strategy.


    OMV AMD64 7.x on headless Chenbro NR12000 1U Intel Xeon CPU E3-1230 V2 @ 3.30GHz 32GB ECC RAM.

    OMV AMD64 8.x on headless Tyan Thunder SX GT86C-B5630 1U Server with Intel Xeon Silver 4110 CPU @ 2.10GHz & 32GB DDR4 ECC RAM.

    I'ved disconnected the disk, and connected it to my laptop. That's also how I ran fsck -v, and I can't see the folders.


    But it would be strange if OMV should corrupt so many folders just because the server crashed, I haven't seen that issue before.
