I made no changes to the machine, and there are no errors being displayed, which is rather weird: # zpool status nm pool: nm state: DEGRADED scrub: none requested config: NAME STATE READ WRITE CKSUM nm DEGRADED 0 0 0 raidz1 DEGRADED 0 0 0 c0t2d0 ONLINE 0 0 0 c0t3d0 ONLINE 0 0 0 c0t4d0 ONLINE 0 0 0 c0t5d0 ONLINE 0 0 0 c0t6d0 ONLINE 0 0 0 c0t7d0 REMOVED 0 0 0 What would your advice be here? What do you think happened, and what is the smartest way to bring this disk back up? Can you send the output of "zpool history nm" ? It consists of a ton of renames and snapshots as executed by my ZFS snapshot cronjob that runs every night. If you want I can setup a job to grep for lines that are not snapshots and renames, but there is nothing other than snapshots and renames on my last page of results. What sort of thing were you expecting to find, anyway? Since there are no errors I'm inclined to throw it back into the pool and see what happens rather than trying to replace it straight away. Thoughts? Sounds like a reasonable plan to me. How would I do so? Attach? Replace? Some other command? I'm not sure how to add a disk to an already established Raid-Z pool safely. In fact, I didn't think it could be done... -- richard -- Joe Auty, NetMusician NetMusician helps musicians, bands and artists create beautiful, professional, custom designed, career-essential websites that are easy to maintain and to integrate with popular social networks. www.netmusician.org j...@netmusician.org
