Updated my unraid to 6.12.6 shortly after bringing the array up noticed then that the cache pool disk is showing an Unmountable disk present (See screenshot)

 

 

 

 

I also noticed that disk 7 in my array is offline - oddlyenough. Might be that i just need to replace it, and the timing is just coincidental. 

 

 

Attached the diag - this is mostly used as a plex server, so if i need to format/rebuild its not the end of the world, but hoping to recover this. Thanks for any help.

Looks like I messed up by adding a 2nd device to the cache pool, stopped array, removed 2nd device, started array and looks good? Whats the best way to add a 2nd device to the cache pool?

 

I'm also fighting a dead drive - might just need to replace it. 

 

Pool is reporting a missing device, post the output of:

btrfs fi show

 

 

 

Here's an updated diagnostic

Pool mounted after starting with just sdb, which is what I was going to suggest, so let the balance finish and post new diags to confirm it was successful, also change the docker network to ipvlan since there are already macvlan call traces.
