I’ve just created two pools on a freshly partitioned disk, using 11.0 amd64,
and the shift appears to be 9:
# zpool status -v host
pool: host
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.
scan: none requested
config:
NAME STATE READ WRITE CKSUM
host ONLINE 0 0 0
gpt/host0 ONLINE 0 0 0 block size: 512B configured,
4096B native
errors: No known data errors
# zdb host | grep ashift
ashift: 9
ashift: 9
But:
# sysctl vfs.zfs.min_auto_ashift
vfs.zfs.min_auto_ashift: 12
Of course, I’ve noticed this only after restoring all the backups, and getting
ready to put the box back into production.
Is this expected behaviour? I guess there’s no simple fix, and I have to start
over from scratch?
