Hi,
I upgraded now a FreeBSD 9 to version 10.
Now my zpool says:
pool: zroot
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: scrub repaired 0 in 42h48m with 0 errors on Mon May 5 06:36:10 2014
config:
NAME STATE READ
WRITE CKSUM
zroot ONLINE 0
0 0
mirror-0 ONLINE 0
0 0
gptid/504acf1f-5487-11e1-b3f1-001b217b3468 ONLINE 0
0 0 block size: 512B configured, 4096B native
gpt/disk1 ONLINE 0
0 0 block size: 512B configured, 4096B native
My partition are aligned to 4k:
=> 34 3907029101 ada2 GPT (1.8T)
34 6 - free - (3.0K)
40 128 1 freebsd-boot (64K)
168 8388608 2 freebsd-swap (4.0G)
8388776 3898640352 3 freebsd-zfs (1.8T)
3907029128 7 - free - (3.5K)
But it seems that the ZFS pool is not aligned correctly.
Is there a possibility to correct that online without taking the pool
offline?
Gruß
Matthias
