Wrong disk

On my first setup I had only one ssd disk on which I installed a MC server. Worked fine until I put 2 more mirrored disks in the server and now ProxMox thinks MC is installed on the NEW disks. Can't find any where to tell ProxMox that it is using the wrong disk and set it back to the first disk, How do I do that?

Getting this message: TASK ERROR: unable to activate storage 'VDisk1' - directory is expected to be a mount point but is not mounted: '/mnt/pve/VDisk1'

Why did you post the error if you don't think it is related?

ETA: You have given just about zero information about your configuration so whatever people offer will be a guess. Show us the output of "lsblk" for example. What steps have you taken and what output did you get? How did you create the mirror?

Have NO idea if it is related. It sure shouldn't be. Only put more disks in the server and after reboot ProxMox can't find my first vdisk.

Never said I created a mirror. Said I put 2 more mirrored disks in it. This is normally possible without interfering with existing disks.
Said I got an error message on my first disk after installing these new disks. The message says that the VM can't start. This means NO lsblk.

I haven't taken any other steps than what I described. I asked because I hoped to figure out what steps to take.
 
Well, that is a little new info. Proxmox can't find your first disk and the VM won't start.

It really sounds like the disks were mounted by name (e.g. /dev/sda) rather than by id and adding new disks changed the enumeration. That or the administrator got confused and mounted things in the wrong place.
 
Did you have declared your mountpoint with uuid partition ? If not, do that before all.
 
I created the VM a few months ago and it worked fine until I put more disks in the server. What can I do/try?

Hey,
how did you have initiated your disk??
you haven’t any gpt schemas on your vdisk

Please log in to your server command line (console or ssh) and post the output of "lsblk" and "cat /etc/fdisk". Then we can help figure out what goes where. If you can't do that it is very hard to help you.

Want to say /etc/fstab I think x')

As I mentioned earlier - The VM won't start so this is not really an option.

I did a setup in the BIOS and ProxMox recognized it when I created the VM so I just selected it and used a part of it as a virtual drive in the VM and it worked fine for a few months until I put more disks in it.

No. I didn't know you were talking PVE host. Would naturally have gone there if I knew.

on pve host, please post the output of "fdisk -l" ans the return of cat /etc/fstab
 
Yeah, I would like to see the outputs @Pifouney asked for. Because it really looks like you have done more than you let on. You've got a couple of disks mounted but no storage defined for them, plus the disk you do have a storage defined for seems to either not exist or be mounted somewhere else. Maybe /mnt/pve/one-tb used to be /mnt/pve/VDisk1?

I am not seeing any disks that are not mounted, which is what I would expect if you had just "plugged in a disk".

OK.
2 choices for U:

- Create a directory storage in your WebUI and select yours mountpoint (/mnt/1tb /tree-tb)
-Destroy actual partition, and initialise them with lvm.
DO NOT INITIALISE them with zfs, you gonna loose yours data.(perc h710)
