In that case, can you reboot and do a screen record (or just use phone), then attach that video?

Are you aware of your RAID config, how it was before? How many and which disks?

Are you able to have ANOTHER alternative boot method (Live CD/USB)?

I have booted to rescue mode. Please let me know if you need any file configuration.

I'm interested in your fstab (probably at /etc/fstab) and your lvm.conf (probably at /etc/lvm/lvm.conf)

The difference in hardware is what is keeping it from booting... The initrd has drivers for the old hardware, and not for the new.

Try this if you can do it on your remote hardware...

Hi,

I have to agree with Scott as it detected 'new usb hardware'.

Cheers

Hello experts,
First of all I have to say sorry for not replying as I had too much hectic last two days because of this problem. I install fresh OS and took my web expert help to configure the website again. As in rescue mode , I had the access to data partition and could able to mount some samba partition, I copied all my data back. The Hetzner guy said that when the motherboard was not working, he swap the disk to other similar server with same hardware. I don't know if he should do this or not. He should have just replaced the faulty motherboard instead of swapping the disk to new server (if I am right !!). He told us that the new server is same as old which only God knows of this. To me and other experts it seems like the hardware was not similar and this is where the server stopped booting.
I want to know if similar things happens in other case, how to make changes in OS so I could boot with new hardware.
Thanks and regards.
