@Emmanuel_perez Thanks for the update and glad you got it sorted. Always a worry this kind of thing.
Yes, Rockstor has to wipe all subvols and the pool when you request a pool delete and if the drives are no longer attached then it errors out on trying to comply. But a warning to folks doing this. It does not just removed db (database) entries, it does what the warning before-hand states, it removes the data from the drives. But if the above procedure of copying over the data has completed successfully, and it’s been verified, then all should be OK. Plus of course we all have those essential 2 backups I’m sure (fingers crossed) .
Thanks again for the update.
@Flox I think we may still have some very old technical/developer wiki entries that suggest otherwise re pool removal that are overdue for an update. We should probably schedule an update to those soon.
