[SOLVED] Remove (removable) datastore

[Elleni]

I would like to know the correct way to remove a removable (external usb disk) datastore from PBS correctly. After removing it by

proxmox-backup-manager datastore remove datapool

I cannot export the pool.

zpool export poolname
umount: /poolname: target is busy.
cannot unmount '/poolname': umount failed
zfs unmount poolname umount: /poolname: target is busy.
cannot unmount '/poolname': umount failed

So how is the correct procedure before physically detaching the external usb disk?

at the moment, you have to reload/restart the services 'proxmox-backup-proxy' and 'proxmox-backup' so they release the lock. after that you should be able to unmount

we plan to have some kind of enable/disable or export/import datastore function, but for now this is not implemented

Thanks for your information. How would I do that precisely? service proxmox-backup-proxy restart && service proxmox-backup restart? Tried the first command but it nothing happening. Cursor stalling in pbs console webinterface.

you can go to Administration -> Services on the GUI to restart the services.

if you prefer CLI then systemctl restart proxmox-backup proxmox-backup-proxy should work

Thanks. That worked. After that I could export the removable disk pool. And thanks that you are planing to have some kind of enable/disable or export/import datastore function.

I'm confused by the above instructions. If the backup and backup-proxy services have things locked, how will restarting them help? You'll still be locked, no? I'm backing up to a hotplug SSD, and if I do the restart command above, I'm still unable to export the pool (granted, export is different from unmount, but still...) I found I have to do this:

systemctl stop proxmox-backup proxmox-backup-proxy

import or export pool

systemctl start proxmox-backup proxmox-backup-proxy
