Have you ever received the “/dev/sda has a holder” error on your Proxmox server when trying to erase/wipe it? We have a solution below
You get the “/dev/sda has a holder” error when you try to erase a disk that was previously part of an LVM Volume Group. You can verify this by running
pvs on the terminal which should return something like:
root@prox:~# pvs PV VG Fmt Attr PSize PFree /dev/sda hack-stor lvm2 a-- <465.76g 215.75g /dev/sdb3 pve lvm2 a-- 231.88g <16.00g
As you can see, /dev/sda is in fact part of the hack-store VG group.
If you are confident you want to wipe the disk, issue the following command to remove the volume group:
root@prox:~# vgremove hack-stor Do you really want to remove volume group "hack-stor" containing 2 logical volumes? [y/n]: y Do you really want to remove active logical volume hack-stor/vm-101-disk-0? [y/n]: y Logical volume "vm-101-disk-0" successfully removed Do you really want to remove active logical volume hack-stor/vm-101-disk-3? [y/n]: y Logical volume "vm-101-disk-3" successfully removed Volume group "hack-stor" successfully removed
That’s it, you’re done!
