[SOLVED] How to use a new logical volume for VM / Container backup

[bond347]

Hi All,

I have created 2 logical volumes (data and backup) from the pve2 volume group.
I converted the data lv to a thin pool and on proxmox mgmt gui add it as storage called local-lvm. This local-lvm content type was disk and container image.

Question is, how could i create storage on proxmox mgmt gui for backup lv and mark the content type for backup, iso, etc.?

Hope someone can help me out.

Hi, in order to store files such as isos or backups you will have to create a filesystem, meaning a directory based storage on top of your LVM.

Hi Chris,

Thanks for your reply.
I'm still new to Proxmox and Linux. Hope you don't mind guiding me. Do the following steps are correct? and please add should i missed the filesystem check or other steps.

1. # mkfs.ext4 /dev/pve2/backup
2. # mkdir /mnt/pve2backup
3. # mount -t ext4 /dev/pve2/backup /mnt/pve2backup/
4. Create Directory-based storage from proxmox mgmt gui

Hi,
yes these steps are right... The only further step to consider is to add a fstab entry for the filesystem to be mounted on boot, otherwise you will have to do this manually every time you reboot
