I''m running snv_95 ----- pool: tank state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 raidz1 ONLINE 0 0 0 c1t1d0 ONLINE 0 0 0 c3t0d0 ONLINE 0 0 0 c2t0d0 ONLINE 0 0 0 c3t1d0 ONLINE 0 0 0 ----- I''m trying to replace c3t0d0, so far i have tried a number of ways... 1. offline the disk, unconfigure with cfgadm, hotplug new disk and zpool replace.
