Re: [zfs-discuss] Proper wayto do disk replacement in an A1000 storage array and raidz2.
Hi-- I'm not quite sure about the exact sequence of events here, but it sounds like you had two spares and replaced the failed disk with one of the spares, which you can do manually with the zpool replace command. The remaining spare should drop back into the spare pool if you detached it. Check your zpool status output to confirm the spare status. If you need to add it back to the pool, then you can use zpool add. You can review more about managing spares, here: http://docs.sun.com/app/docs/doc/817-2271/gcvcw?a=view Your questions have reminded me that we need a better example of the failed disk--spare replacement scenario in this guide so I will add one. Thanks, Cindy Demian Phillips wrote: Thanks. I have another spare so I replaced with that and it put the used spare back to spare status. I assume at this point once I replace the failed disk I just need to let solaris see the change and then add it back into the pool as a spare (to replace the spare I took out and used in the replace)? I see some odd behavior related to the FC array and controller but that is not ZFS related so I will have to post elsewhere about that fun.

Re: [zfs-discuss] Proper wayto do disk replacement in an A1000 storage array and raidz2.
Hi-- You can replace the failed disk and then detach the spare using the general scenario described below. Some steps might be optional but I'm pretty cautious about disk replacement, even when its this easy. Cindy 1. Physically replace the failed disk. 2. Let ZFS know that you replaced the failed disk. If you replace the failed disk with a disk in the same position, say for example, c1t0d0, then use syntax similar to this command: # zpool replace pool-name c1t0d0 2. Run zpool status to confirm the replacement is successful and the resilvering is complete. 3. Detach the spare, like this: # zpool detach pool-name spare-disk 4. Run zpool status again to confirm that the spare is back in the pool. Cindy Demian Phillips wrote: I'm using ZFS and a drive has failed. I am quite new to solaris and Frankly I seem to know more about ZFS and how it works then I do the OS. I have the hot spare taking over the failed disk and from here, do I need to remove the disk on the OS side (if so what is proper) or do I need to take action on the ZFS side first?

Thanks. I have another spare so I replaced with that and it put the used spare back to spare status. I assume at this point once I replace the failed disk I just need to let solaris see the change and then add it back into the pool as a spare (to replace the spare I took out and used in the replace)?

I'm using ZFS and a drive has failed. I am quite new to solaris and Frankly I seem to know more about ZFS and how it works then I do the OS. I have the hot spare taking over the failed disk and from here, do I need to remove the disk on the OS side (if so what is proper) or do I need to take action on the ZFS side first?
