BTRFS Commands For Deleting Pools

I dropped the top of my desk on one of my external hard drives when moving it. Interestingly enough, I thought the disk might survive it. But no, it is DOA.

Luckily Rockstor is one backup of many. I start up the Rockstor machine, but everything is stalled. I can’t really view or delete the pools or anything like that in the web UI.

I removed the disk in question because it is going to have to go into the bin. But really what I want to achieve is removing the pool that is broken.

If I drop out into the command line I get this,

[root@nas ~]# btrfs fi show

Label: ‘rockstor_rockstor’ uuid: 7c01412f-5b44-4f2a-bb79-37c661976ded
Total devices 1 FS bytes used 5.81GiB
devid 1 size 1.81TiB used 9.08GiB path /dev/sda5

Label: ‘NewPool’ uuid: b9224dec-dae5-4c07-ab6d-eb8b96dc02af
Total devices 4 FS bytes used 4.47TiB
devid 1 size 1.82TiB used 448.01GiB path /dev/sdb
devid 3 size 2.73TiB used 1.35TiB path /dev/sdd
devid 4 size 3.64TiB used 2.26TiB path /dev/sdc
*** Some devices missing

How in the command line can I delete the NewPool?

An additional question I suppose as an alternative, can I install Rockstor on a USB stick?
