Error in proxmox, suddenly I can't enter the web interface, but the VPS seems to still work correctly.

Hello!

I just had a "dumb" problem.

I was doing some tests to measure the speed of the disk and suddenly I can't access the web interface, but it seems that all the servers are still working.

I get these errors:

root@prox3:~# dd if=/dev/zero of=/dev/md2 bs=64k count=16k conv=fdatasync

How can I fix it?

Greetings!

Um yeah you succesfully wiped the first 1gb of your drive, which is enough to break the whole system...

How does it come its md2 ? mdraid isnt supported by proxmox afaik. Nevertheless if this was your rpool as it seems you are screwed.

Reinstall proxmox and restore from backup, there is not much else you can do.

Yes, I've realized I have a serious problem.

I saw that the VPS is on the road:

/var/lib/vz

I've already lost access to the server. By moving those files, can I recover the servers in a new proxmox installation?
