[SOLVED] Need Help - vgremove removes my machines ?

[Tarek Damak]

Hello Evrybody ,

I'm new with proxmox but i really liked it , but now i have a little problem :
snapshots are disabled (can't even click it) for some VMs (who are located in a virtual disk ab1 that i made using vgcreate so he's not in the pve disk) but in the machines on the pve disk can be snapshoted .

I'm trying to remove the virtual disk ab1 and then extend the pve and i think that will let me able to do snapshots ,
but i wanna know if i remove my ab1 disk , will i lose all my machines who are in ab1 disk or they will be found directly in the pve storage after extending it ? because they are already in the production so i don't want to stop them for 1 or 2 days

Thank You

if you remove a lvm volume group, all disks on it are lost

the disks on the default storage can be snapshotted because there we use an lvm thinpool by default

please make yourself familiar with lvm

man lvm
man lvmthin

Thank You Dominik ,
i'll start reading about it

So the solution that i have is to make my second storage uses lvm thinpool ?
But can i do it when it's created or i have to delete all my data and recreate my storage ?

If you deliberately remove it, this will not solve the problem. Just do not remove stuff :-D
