I upgraded a 6 drive RaidZ2 set from 4TB drives to 10TB drives. This is what I used to swap out the last drive:

# zpool replace logrus diskid/DISK-PK1334PBG6AWBSp1 diskid/DISK-2YJ7LSZD

This is the result:
# zpool status logrus

Code:
  pool: logrus
state: DEGRADED
status: One or more devices has experienced an error resulting in data
        corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
        entire pool from backup.

errors: 275 data errors, use '-v' for a list
I'm really confused what all the different error counts are. Nothing seems to agree, and I've never seen checksum errors on the raid name and "raidz2-0" part before. Any ideas?


# uname -a
FreeBSD suhuy.local 12.0-RELEASE FreeBSD 12.0-RELEASE r341666 GENERIC amd64

using -v flag on zpool status:
Code:
