kern/145712: [zfs] cannot offline two drives in a raidz2 configuration (8.0-stable)

Synopsis: [zfs] cannot offline two drives in a raidz2 configuration (8.0-stable)

State-Changed-From-To: open->suspended
State-Changed-By: pjd
State-Changed-When: czw 13 maj 2010 22:26:48 UTC
State-Changed-Why: 
This problem is fixed in recent ZFS, but the fix is too intrusive to
back-port it. It has to wait for new ZFS import.

BTW. This issue also exists for N-way mirrors where N > 2.
