Hi all,

I setup proxmox, and liked it very much, and as everything was working like a charm, i setup our servers and everything., and today that we are going live, my system does have a serious problem, and I really hope, there is a way to recover, as in some hours my coworkers come here, and during this weekend we changed all our systems depending to this proxmox installation.

I have a raid1 zfs proxmox that was working fine, until last night, I wanted to make a full backup, thus pluged in an external usb disk. As it was not recognized by the vm when adding it to it to the vms, I tried and added it as pci device. Soon after proxmox did was not reachable anymore, so I went back to my workplace and now I see that proxmox boots but soon after root login prompt, there are the following messages. Failet to set apst feature (-19), then usb devices are deregisterd/disconnected and there are zio poolpool=rpool ... error=5 messages. then there are warnings pool rpool has encountered an uncorrectale i/o failure and has been suspended, soon after there is a kernel panic, if I interpred that correctly.

Now I am really panicing. Please tell me there is a way to recover, as I am in big trouble. Is there a way to see from booted proxmox install cd if there is a change to not loose all my work? I have a prompt root@proxmox from proxmox installer cd.
 
Does the VM autostart on boot? If so, then you will need to boot into the debug mode of the Proxmox VE install ISO, abort the wizard and import the zpool. Once the pool is visible you will need to chroot into the alternative root. Then start the pve-cluster service to get /etc/pve mapped. There you can find the config of the VM and remove the line with PCI.

The probable cause might be that you selected the wrong PCI device for passthrough. And ZFS loses its disks when the VM starts.
