Hi,
yesterday i moved my ZFS pool from 2 SSD (S-ATA) to 2 brand new NVMe Disk. I used the "zpool replace -f" command to move the data. When moving the first disk it seems to be all right and zpool status showed no error. After resilvering was done i moved the next disk and suddenly checksum failure came up on disk1. I didn't want to interrupt the resilvering of disk 2 so i decided to let it run until the end.
Today i run zpool scrub and got this:
I'm not shure what do do now. Delete the ZFS and restore from yesterday Backup? On the new disk or on the old disk? Is it possilbe to repair the ZFS?
What do you think?
Kind regards
Jochen
