Im facing a problem with one server with OpenVZ7 + Virtualizor. After running yum update and rebooting the server the server no longer booting into OS, but in rescue mode we can mount boot partition, /vz partition and / partition without any problem.
The server currently showing unable to find boot drive during boot.
The server having raid1 array mirror and its working perfectly. Both of the storage are in healthy state.
Im looking for a sysadmin who can fix the OS boot issue or, recover the server to another server from rescue mode.
root@rescue ~ # cat /proc/mdstat

do you have vnc access.
try to see the boot logs, maybe a mount is missing?
I have IPMI access and RESCUE mode. How can I fix this, if you can guide me. I want to hire someone to fix the problem.
open up the IPMI and boot into the bootable disk "without rescue"
do you get a non bootable device or what messages do you see?
Im getting > non bootable device after bios screen.
root@rescue ~ # mount /dev/md126 /mnt
root@rescue ~ # mount /dev/md124 /mnt/boot
root@rescue ~ # mount /dev/md127 /mnt/vz
