May 16, 20251 yr Not unraid literate yet, but server was up and running for some time. However, upon a reboot (nothing changed on my end) I get the error shown below. Also is a pic of my setup, as well as the zpool import command data, and config file attached. The slog says corrupted, but I believe that is just because the slog is an intel optane drive while the motherboard does not support it, and I haven't taken it out, because I'm still a n00b and don't even know how to safely do that. Though it has been working with it in since I built it several months ago. I've read that you can unassign all the drives, start array, stop array, reassign all drive then start again to fix, but that just gives me more errors. My USB stick may be going bad, as now it seems the motherboard only finds it about half the times on a reboot. tower-diagnostics-20250516-1316.zip Edited May 17, 20251 yr by jlwitherell clarity
May 17, 20251 yr Community Expert The special sub-pool has the wrong config, you can just reimport the pool: on main click on the first device for that pool and then "remove pool" back on main, create a new pool with the same name and 8 slots assign the pool devices all together, don't create sub-pools, leave the filesystem set to auto start the array to import the pool
May 17, 20251 yr Author Thank you, that let me start the array but it looks different now (see pic), though Plex seems to be working fine. The cache not installed is the unsupported optane drive as the write cache. The other, now showing as cache 2 is the read cache. Is this right now, even though it looks different than before - not showing "slots"? Sorry for my ignorance on the matter. and thank you again! Edited May 17, 20251 yr by jlwitherell clarity
May 18, 20251 yr Community Expert One of the cache devices may have an issue, post current diagnostics.
May 18, 20251 yr Author For sure there is an issue with the Optane drive I tried to set up as slog, my motherboard doesn't support Optane drives. I have a pcie optane coming and will replace that. Diagnostics attached. What is the process to replace the slog vdev drive? Thank you so much for the help! tower-diagnostics-20250518-0959.zip
May 19, 20251 yr Community Expert The GUI doesn't support replacing devices from non-redundant subpools, like cache, I would recommend removing both devices from the cache subpool, you can see here how: https://forums.unraid.net/topic/46802-faq-for-unraid-v6/page/4/#findComment-1512308 Then reimport the pool without that subpool, and you can then add one or mode devices to create a new cache subpool.
