BTRFS warning (device loop2) - again

[pballs]

Getting:  BTRFS warning (device loop2): csum failed root 368 ino 4162 off 53346304 csum 0xbf0b209e expected csum 0x20aadd8c mirror 1 warning

 

I had this issue a while ago - recreated docker.img and re-installed all apps - and it ran fine for a month or so, and its happened again now - is there something else i should be doing to fix this?

 

Diags attached and thanks in advance

looks like the issue happens immediately after a CA Backup/Restore Operation:

Don't see any issues before the checksum error, but if it keeps getting corrupt you might have a hardware issue, if it's an option try recreating the image on a different device.

oddly, a restart of the docker service cleared the issue..

It will very likely happen again, once it tries to read the corrupt blocks.
