How run e2fsck on pve installation ssd

[DLuke77]

Hi all!
I'm trying to do an image of my BM installation of Proxmox with Clonezilla, but it fails saying that there are some error on some partition and suggest to check the integrity.
But i don't know how, because if i try with e2fsck on dev/nvme01 says that it's in use ad so every other partition/disk related to proxmox.
I tried also with a Ubuntu Live cd to do the same, but with no luck, or tell that are in use or that i'm not root so i can't access (obiouvsly i'm logged like root)
What can i do?
Thanks very much!

That should always work. Maybe the disk was automaticalls mounted? Please check and umount everything. You should get a root shell if you have problems with sudo, so please just run sudo su - to get a root shell and try again from there.
