On a remote server, I replaced a dead 2TB disk with a new one that had
4096K sectors.
2014-12-11.22:40:30 zpool replace -f tank1 16144392433229115618 /dev/ada0
My ZFS pool then warned me after
pool: tank1
state: ONLINE
status: One or more devices are configured to use a non-native block size.
Expect reduced performance.
action: Replace affected devices with devices that support the
configured block size, or migrate data to a properly configured
pool.
Camcontrol and smartctl confirm the 2TB drive was indeed 4096. (All my
previous ones were 512, so didnt think to check)
# camcontrol identify ada0 | grep secto
sectors/track 63
sector size logical 512, physical 4096, offset 0
LBA supported 268435455 sectors
LBA48 supported 3907029168 sectors
# smartctl -a /dev/ada0 | grep -i 512
Sector Sizes: 512 bytes logical, 4096 bytes physical
So, with a new drive, I replaced the 4096 drive
2014-12-16.17:07:14 zpool replace tank1 ada0 ada11
# smartctl -a /dev/ada11 | grep -i 512
Sector Size: 512 bytes logical/physical
# camcontrol identify ada11 | grep -i sector
sectors/track 63
sector size logical 512, physical 512, offset 0
LBA supported 268435455 sectors
LBA48 supported 3907029168 sectors
yet, zfs is still complaining
# zpool status
pool: tank1
state: ONLINE
status: One or more devices are configured to use a non-native block size.
Expect reduced performance.
action: Replace affected devices with devices that support the
configured block size, or migrate data to a properly configured
pool.

This is RELENG_9 r275680
Any ideas if the reporting is cosmetic ? Or there is an issue
Sorry for the xpost as this is sort of both a hardware and config issue.
