Cannot replace disks in pool

[Dariusz1989]

Code:

zpool replace -o ashift=9 ggmtank01 gptid/<faulty-rawuuid> gptid/<new-rawuuid>

You most likely don't want shift=9 here... ashift9 means its 512 block and you probably want 4096 which is ashift=12...
There is a command to read which ashift ur pool is configured at that you should follow I think?

@Dariusz1989 You are right - and zpool status tells me so! But for the moment i take the non-degraded fully resilvered RaidZ2 VDEV over performance!

Code:

# zpool status -v ggmtank01
  pool: ggmtank01
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.

thankyou for posting the detail and fix for this issue.

Had a failing disk in a vdev mirror. The disks in that vdev had a different ashift value to the rest of the pool (how???).

Resilver is now in progress
