July 14, 2025Jul 14 Alright, I am in sticky situation that is entirely my own fault.A few weeks ago I had a drive bay die I thought, but only noticed today that the drive while still showing as emulated, also appeared in unassigned devices.I messed around with getting it to recognize that the drive was installed, but then could not mount the Array.I was receiving errors due to corruption issues on one of my cache drives. I have 3 x 2tb M.2 cache drives.I removed the cache drive which was causing issues. I wanted to format the one bad cache drive and drop it back in.Currently, the remaining 2 cache drives (which IN THEORY shouldn't have lost any of the data) are showing Unmountable: Unsupported or no file systemI cannot mount using unassigned devices because I get (Jul 14 14:08:28 Tower kernel: BTRFS error (device sdk1): devid 1 uuid 68407192-fbc8-44ff-9e01-1adfbc4a79f3 is missing)Is there anyway that I can repair or be able to pull data from the 2 remaining drives? tower-diagnostics-20250714-1402.zip

July 15, 2025Jul 15 Author Of the original pool of 3 cache devices.1 - I thought this was the problem device. It has been wiped and is functioning as the current cache drive alone.2 & 3 - They are sitting in unassigned devices. Neither appear as mountable. I understand that I have definitely made the situation worse. I'm only trying to browse and pull files if possible.
July 15, 2025Jul 15 Community Expert 1, 2 and 3 dosn't really tell me which devices. I assume they were sdj, sdk and sdl?
July 15, 2025Jul 15 Author I apologize. SDK and SDL are currently sitting in unassigned devices. SDJ was the device that was initially throwing errors.Current diagnostics attached. tower-diagnostics-20250715-1123.zip
July 15, 2025Jul 15 Community Expert sdj was reformatted, correct? And sdk is not being detected as part of that pool, so I'm afraid that a 3 pool device with two devices missing won't mount.Possibly, the pool was already degraded before with just sdj and sdl, now that sdj is also not present, it won't work.
July 15, 2025Jul 15 Author SDJ has been reformatted. SDL and SDK are detected in unassigned devices, but neither will mount.
July 15, 2025Jul 15 Community Expert 5 minutes ago, EMAN4705 said:SDL and SDK are detected in unassigned devices, but neither will mount.Nope, because it's a 3 device pool missing 2 devices, it cannot mount.
July 15, 2025Jul 15 Author Damn. Well I really appreciate your help.I should've sat still and waited for the experts.
