[OpenIndiana-discuss] replacing a failed drive?

[Dan Swartzendruber]

Trying to help someone on a public forum.  He is trying out OI per my 
advice.  He has a two-vdev raidz2 pool, with one spare drive.  One drive 
apparently died, so it is showing as removed.  He was surprised the 
spare didn't kick in.  I told him to do 'zpool replace POOL OLDDEV 
NEWDEV'.  He did and got "cannot replace c5t7d0 with c2t1d0: devices 
have different sector alignment".  I had him do a 'prtvtoc' on both 
devices, and they look absolutely identical!  This doesn't look right, 
does it?  I'm having him try a couple of things: 1) use the '-f' flag to 
try to force it, or 2) power off, unplug the dead drive, plug the spare 
into the same slot and reboot (possibly doing 'zpool replace POOL 
OLDDEV'.  Any thoughts?
