I have recently built a mini home system, raidz2, with five 3TB drives resulting in about 7TB ZFS pool. I have added a sixth drive as a spare. The cabinet has room for eight drives. Does the forum have a recommendation for the number or ratio of spare drives? If experience says zero, then...

Just had a data drive fail. The Hot Spare kicked in. The good drive was resilvered without errors. However, the pool is still showing as DEGRADED. What additional steps do I need to take? I did try to put /dev/gptid/a7296f03-9690-11e9-ac10-3cfdfecf5af8 OFFLINE. It's currently OFFLINE now...

Running 11.1-U6. My pool consists of: Four 11-drive RAID-Z3 vdevs Two striped L2ARC SSDs One hot spare Last week one drive in one of the vdevs had a self-test log error count increase from 0 to 1, so today I went ahead and offlined it and initiated an RMA for that drive. However, I had...

Hi Guys, Looks like I have a pool in a degraded state, I think because the hotspares kicked in. This system is running FreeNAS 11.1-U4. Please take a look at this zpool status. I assume I need to detach the faulted drives and the spares will become permanent from what I have read...

I have one drive starting to report bad sectors, so I need to swap it... I have identified it, and taken it offline. My pool dropped to a degraded state as it should, but my glorious "hot spare" is just sitting there showing "available". If I click the "replace" button on my offline disk...

So I'm gearing up to add more drives to my server and redo my RaidZ to a RaidZ2 but I'm unsure how I want to go about doing my spare drive. My plan is to do a 6 drive RaidZ2 with 4TB drives and having one Spare. I'm not sure if I want to have a hot spare or a cold spare. What does everyone think...

I have a failing disk in one of my volumes that has unreadable/pending sectors. This is not a problem though as I have two hot spares sitting in the machine ready to go. The two hot spares are sitting in a spares volume. When I select the failing disk, da6, and select replace and select one of...

Running FreeNAS 11 on a new machine that I am testing. I have a pool with 6 disks, 5 drives plus a spare (hotspare?) I meant to add a drive to the 7th bay, but accidentally popped the 6th bay. No drama, I waited for the pool to resilver, shut down, popped the drive in, and then "replaced" the...

Hi all, Help! We currently have a spectacular zpool status which contains the following: state: DEGRADED status: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected. action: Determine if the device needs to be...

I am currently in the process of setting up my new NAS, and I want to implement a hot spare that automatically rebuilds my RAID array (4x3tb RAID 10) when a disk fails. If I understand correctly, FreeNAS doesn't do this? Apparently you have to manually tell the hot spare to kick in, and the hot...
