It appears that there's corruption on the cache drive / nvme  @JorgeB is the best to respond / offer up suggestions.  Wait for him to reply.

Thank you I'll wait for him to respond before trying anything.

It is a cache pool with 2x 1TB nvme by the way

[JorgeB]

Yes, the pool is making Unraid crash, cannot see why though, unassign both pool devices, start the array and then see if you can mount them using the recovery options here, if the first options doesn't work best bet is to use btrfs restore.

[Johann]

Good news, I was able to brtfs restore onto a spare hard drive I have, and I unassigned the pool devices, erased one and copied the files onto there, boots right up. I kept the second pool device as backup. I didn't try the first option since I already started the second.

 

I made it into a single drive cache, with xfs and I'll probably do very frequent backups of it. I've read that others have issues with btrfs as well...

[Johann]

Thank you both for the help!
