Took me some time to get back around to this, and I definitely found a couple of corrupted files while attempting to backup the drive, but the reformat cleared the scrub errors. Thanks for the help!

I've attempted to run the scrub command, however it seems to be aborting and not completing it's run.

Ran Memtest and passed. Then ran the btrfs rescue command and restarted and that seems to have fixed the issue as the disk has mounted itself again. Updated diagnostics attached just in case there are other issues lurking in the background I should be aware of. unraid-diagnostics-20250306-2219.zip

I recently updated my machine from the 7.0 stable release to 7.0.1. Upon restarting, my cache drive (a single NVMe drive formatted with BTRFS) would no longer mount complaining of "Wrong or no file system". I attempted rebooting the machine, no luck. I then started the array in maintenance mode and ran a file system check from the WebUI. The reported errors were significant in number and various (checksums not matching, ref check failures, unresolved ref dir). The official documentation is a bit light on next steps as the recommended usage of the scrub command isn't possible without a mounted file system. Happy to provide more details if required but unsure of what the next steps should be to try and recover the drive unraid-diagnostics-20250305-2250.zip
