Migrated disk from NFS to iSCSI - Unable to Boot
This is a new one. I migrated from an NFS share to an iSCSI share on a small single node oVirt system (Currently running 4.3.10). After migrating a disk (Virtual Machine -> Disk -> Move), I was unable to boot to it. The console tells me "No bootable device". This is a Centos7 guest. I booted into a CentOS7 ISO and tried a few things... fdisk -l shows me a 40GB disk (/dev/sda). fsck -f tells me "bad magic number in superblock" lvdisplay and pvdisplay show nothing. Even if I can't boot to the drive I would love to recover a couple of documents from here if possible. Does anyone have any suggestions? I am running out of ideas.
I think I figured this one out. Looks like the disk format changed when moving to block storage. The VM template could not cope with this change. I deleted the VM, and attached the disk to a new VM, and everything worked fine. On Tue, Oct 27, 2020 at 8:41 AM Wesley Stewart <wstewart3@gmail.com> wrote:
