Is there anything that can be done? While googling some things I saw another unraid post mention running the command "btrfs fi show /dev/sde1" which outputs the following, it still shows used space.

iarp Posted August 3, 2021 Author Share Posted August 3, 2021 (edited) The 3rd command listed under the read-only section "ro,notreelog,nologreplay" worked and I'm copying as we speak. It's unclear to me if this is a failing drive or something else happened and i'm safe to just reformat and put it back into service. I grabbed diagnostics before shutting it down the first time, according to my emailed errors this happened at exactly 9AM my time. Edited August 4, 2021 by iarp Quote Link to comment
JorgeB Posted August 3, 2021 Share Posted August 3, 2021 Drive looks fine, could still be hardware related, like a RAM or similar issue, not bad idea to run at least one pass of memtest. Quote Link to comment
iarp Posted August 3, 2021 Author Share Posted August 3, 2021 (edited) I reconnected the drive to the system and ran memtest which found no errors. Upon restarting into unraid the cache drive is randomly back. Should I trust this is ok? Edit: I didn't trust it and attempted to rm the appdata folder because i had already restored that using a backup directly to the array and i didn't want things to get mixed. I'm hit with the following message on hundreds of files rm: cannot remove 'appdata/jellyfin/dlna/system/Sony Bravia (2014).xml': Read-only file system rm: cannot remove 'appdata/jellyfin/dlna/system/Sony PlayStation 3.xml': Read-only file system rm: cannot remove 'appdata/jellyfin/dlna/system/Sony PlayStation 4.xml': Read-only file system rm: cannot remove 'appdata/jellyfin/dlna/system/WDTV Live.xml': Read-only file system rm: cannot remove 'appdata/jellyfin/dlna/system/Xbox One.xml': Read-only file system rm: cannot remove 'appdata/jellyfin/dlna/user': Read-only file system But other files on the system can be deleted without issue. Edit 2: I'm now hunting for a way to somehow verify every bit of an ssd to see if it catches some kind of error? I'm not sure if thats possible. Edited August 4, 2021 by iarp Quote Link to comment
