Missing access to hard drive

[allanl]

I added two drives in my Dell server and configured them to be seen before booting back into Proxmox 8.3. Everything came back including allowing setting up the two new drives, but one drive had a ? against it as it didn't mount.

I thought that I could mount it in a shell, but I don't know how to do that, copy off all of the files to another drive, delete it and rebuild to allow copying back and then reboot the system. Is that the best way to do it, or...? And how do I find the missing UUID or other information to mount the drive, since it's not in the fstab file? It's possible that the Dell location of that drive moved so couldn't mount.

And is there are way to create a Proxmox backup for restoration purposes. The is the contents of the fstab file -

# <file system> <mount point> <type> <options> <dump> <pass>
/dev/pve/root / ext4 errors=remount-ro 0 1
UUID=921A-D078 /boot/efi vfat defaults 0 1
/dev/pve/swap none swap sw 0 0
proc /proc proc defaults 0 0

Thanks for the advice.

If you need the UUID for that disk, you can use the blkid command, then update/add it to the fstab file. I like to backup config files, snippets, etc. to an NFS share if I am doing any kind of reprovisioning work on the host itself.

Maybe mount the drive from CLI, and look to see what is on it, then copy off what you need. I assume you aren't rebuilding the boot drive, so your milage may vary.
