February 17, 20242 yr Hello, Today I woke up to a failed backup and and errors on my ZFS raid0 pool. I destroyed the latest snapshots and am left with 1 error: The drive in question reports: Yet smart tests pass without issue. The error is in an active windows VM vdisk. The VM in question seems to be running without issues. What should I do to fix tis? Is the drive still reliable? Edited February 17, 20242 yr by Laov
February 17, 20242 yr Suggest running memtest first, but since the errors are limited to one device it could be a device problem, what brand/model are the NVMe devices? You can then try a scrub, if error remains file should be restored from a backup.

The drive in question is Samsung SSD 970 EVO Plus 1TB Other 2: KINGSTON SKC2500M81000G XPG GAMMIX S50 Lite Basically random SSDs that I had laying around. That samsung SSD came extra with the used threadripper I got cheaply. Might be faulty Is snapshot considered a backup? The file itself is a VM vdisk and the VM seems to have no issues. I run the backups monthly so rolling back to 1 month ago is not desirable...

Yes, if it's also not corrupt. 19 hours ago, Laov said: The file itself is a VM vdisk and the VM seems to have no issues. The vdisk is almost certainly corrupt, but it could be a small corruption and in a place that doesn't have any data, or place that is not frequently accessed, it would still be preferable to restore from a backup if possible,.
