Description Christian Geier 2012-11-04 17:50:01 UTC 
I did a fresh install of FreeBSD 9.1-RC2 and imported an originally 4 disk zraid pool with only 3 disks attached in readonly mode (via zpool import -o readonly=on storage). On replacement of the missing disk via zpool replace storage ada1 the machine reboots instantly (with no messages in the system logs). I repeated the procedure five times with the same outcome. On importing the zpool without the readonly option, resilvering starts and works fine.

How-To-Repeat: Mount a degraded raidz with '-o readonly=on' and than do 'zpool replace poolname newdisk'

^Triage: I'm sorry that this PR did not get addressed in a timely fashion.

By now, the version that it was created against is long out of support.
As well, many newer versions of ZFS have been imported.

Please re-open if it is still a problem on a supported version.
