Cache Rebuilding?

[fiore00713]

Long story short some sort of oops happened last night and one of my drives was removed from the Cache pool. Figured no big deal, re-add the second drive, start the array and it would go to work.

It appears to have done so, but I'm also suspecting something might be going on that's not so right.

 

My log is flooded with:

Oct 29 15:47:39 unRAID kernel: BTRFS info (device sdad1): found 1 extents

 

The size of the cache pool is reporting incorrectly as 1.5tb (this has been changing since last night) and running 

 

btrfs fi usage -T /mnt/cache   looks a little odd to me but I'm not versed enough to know what exactly might be up

 

I feel like I may need to run a rebalance to get things back to RAID1 happy status but I wanted to get some input first before I went willy-nilly screwing around with it.

 

Diags attached. 

 

Thank You

I don't know how you did it but you have the same device (sdab1) as multiple devices in the pool, no idea how to correctly recover form that, recommend backing up current pool and re-format.

Is there a 'best practice' way you'd recommend to do this?

So for what it's worth I rebooted and now one of them says they're missing >_>

Move anything important from cache to array and re-format pool.
