Prob more of a BTRFS question than Rockstor par se. Our Rockstor has a pool with a share. It can no longer be browsed by an NFS or Samba client. Just freezes. This started after deleting some old snapshots using the Rockstor UI and then doing a test replication (more likely instigated by the former). The share is pretty big - 5tb.
It seems to be related to the fact there's a process that's usually at 100% utilisation: btrfs-transacti, because occasionally this drops to near 0%, and I can briefly browse the share again. I've tried rebooting Rockstor, but the same happens. Are BTRFS snapshots a bit like VMWare, in that if you delete many of them, you can expect a long wait while a merge-with-parent operation occurs? Is it possible I have a corrupt pool or will this eventually sort itself out? It's been 3 - 4 hours so far.
If corrupt, some googling suggests I should try booting off a USB stick and running command: btrfs check --repair /dev/sdXX I assume, I'd run it against Pool1's /dev/sdXX path? If so how do I discover what this is? Is running this command destructive?
