I followed this guide on Unraid7.beta4, which i had to upgrade to because my pool had a zfs feature flag unraid 6 can't handle.
When i try executing zpool export backup i get "cannot export 'backup': pool is busy" and if i ignore this for now and try starting this pool i get: "Unmountable: no file system"
Oct 27 15:46:54 bastion emhttpd: mounting /mnt/backup Oct 27 15:46:54 bastion emhttpd: backup: mount error: no file system
What could i try ?
