I have a DELL server with Proxmox 5.2 installation and all disk on ZFS. 4 Disk on raidz2 for VM and storage, then 2 disk on RAID1 for OS. One of the 4 storage disks on raidz2 failed and I have to put it offline with the plan to change disk and then do a zfs replace after reboot.

On restart the system no longer boot. It just stucked on "Booting from hard disk C".

There was no issue on the ZFS RAID1 for the OS so I am wondering what could be the issue.

Please how do solve this?
 
Hi,

please correct me if I'm wrong, but I assume you Dell sever has a Raid Controller.
ZFS is not compatible with raid controllers.
 
Hi @wolfgang, this is true. However, have disabled RAID and have Proxmox with ZFS running over a year already on this machine with no issues.

Anyways, I was eventually able to reboot with the proxmox ISO in boot rescue mode.

It appears the system have messed up the disk labels /dev/sda - sdd so an export and import by-id have resolved this issue.
