zfs discuss - Jul 2008 - offlining a slice in a raidz not allowed

I''ve a raidz1 made up of 2 partitions. One is on a disk which is
failing and
i want to replace it... cfgadm does not allow me to unconfigure it since
''device busy'', so i am trying to offline the slice from the
raidz1 vdev but
got this error:

 

# zpool offline swap c3t2d0s0

cannot offline c3t2d0s0: no valid replicas

 

given i have 2 partitions in this raidz1, i expected that this vdev acts
similar to a mirror and allows to offline it

 

thanks

justin
