May 6, 20233 yr SO i got a warning that my ZFS pool was degraded. Luckily im running ZFSZ2 but i need to replace these drives and thats the part i need help with. I have all 8 drives on one card, and need to replace the 2 drives that are faulted. I keep searching for an answer online, but its for other things like FreeNAS or whatever. Im just trying to figure out can i just bring the drives offline , swap the new drive in its place and replace it? is there a good guide to do this? any help would be appreciated im fairly new to ZFS, and was lucky enough to get this going a few years back.
May 6, 20233 yr Did u try replace command ? Try a zpool status -xv mulgore for more details Try to repair: zpool scrub mulgore (can be long) zpool clear mulgore request after with zpool status For replace : zpool replace mulgore bad_device new_device

May 6, 20233 yr Anyway yours disks are dead (zfs point of view). I'll suggest to remove one failed disk and replug a new one, normally zfs should resilver it. I m more familiar with solaris version of zfs. What about the scrub command? Edited May 6, 20233 yr by coxifred

May 7, 20233 yr SMART looks OK for both disks, but both are showing some UDMA CRC errors, so you should replace the SATA cables, then type zpool clear mulgore and run a scrub. Also note that you can upgrade Unriad to 6.12, import the pool and then use the GUI to manage it.
