Possible to create a normal fat LVM along side lvm thin for Proxmox

[nadrigo]

Hi there,

Is it Possible to create a normal fat LVM along side lvm thin for Proxmox? I have set it up but I have two more hard drives I want to combine into one LVM. This way I can create a VM with 2TB drive in it as a file server. I want to use two 1.8TB drives into one LVM. I tried adding them to the LVM thin pool but it didn't work. I used old instructions which didn't work in the end so I reinstalled Proxmox and started over. I already have a NAS that acts as the true file server. This VM would be a back up of the NAS etcs... Anyone?

Thanks.

Hi,

yes this is working but I would recommend you to make two different pools.
One for LVM and one for Thin-LVM.
There are situation where it can make trouble .
Is there is are real reason to have a single pool?

Thanks for the reply... I could not add the new drives. I tried using these instructions below and then found out that they are outdated so I started again.

Is there newer documentation to add two drives to the thin-lvm? When I got to the end of the instructions I could not resize the volume I got this error:

resize2fs: Bad magic number in super-block while trying to open /dev/mapper/pve-data
Couldn't find valid filesystem superblock.

Then I was told to use:
lvresize --poolmetadatasize +<size[M,G]> <VG>/<LVThin_pool>

I could not get that to work... My knowledge in LVM is very limited so that doesnt help.

Again I would recommend you to create a new pool.

Yes your correct this is very outdated and has not much to do with your problem.
I will take care about it.
