So, I've done a bit of research and RTFM, and haven't found an answer. If I've missed something obvious, please point me in the right direction.
Is there a way to manually fail a drive via ZFS? (this is a raid-z2 raidset) In my case, I'm pre-emptively replacing old drives with newer, faster, larger drives. So far, I've only been able to come up with two solutions to the issue, neither of which is very graceful. The first option is to simply yank the old drive out of the chassis. I could go on at-length about why I dislike doing that, but I think it's safe to say everyone agrees this isn't a good option. The second option is to export the zpool, then I can cfgadm -c disconnect the drive, and finally gracefully pull it from the system. Unfortunately, this means my data has to go offline. While that's not a big deal for a home box, it is for something in the enterprise with uptime concerns. >From my experimentation, you can't disconnect or unconfigure a drive that is part of a live zpool. So, is there a way to tell zfs to pre-emptively fail it so that you can use cfgadm to put the drive into a state for a graceful hotswap? Am I just missing something obvious? Detach seems to only apply to mirrors and hot spares. --Tim
