Re: Restore from Backup
In your previous environment, you had this in your fstab:
#/dev/vdb /opt ext4 defaults,noatime 12
UUID=6d930f71-6993-4442-926a-be1a23b20f4f /opt ext4 defaults,noatime 1 2
UUID=9b046257-af4e-45c5-b1db-8461f8bc6980 /opt/ZBack/backup ext4 defaults,noatime 1 2
In your new environment /home/opt has been populated from the contents of those 2 disk mounts and is now part of the same disk partition. Is that correct?
If that is the case, you can comment out both those UUID lines in /home/etc/fstab and you no longer have other partition to mount at /opt and /opt/ZBack

Re: Restore from Backup
I am thinking add this to /boot/grub/grub.conf below the other entry
Make the changes to /home/etc/fstab that I mentioned ... Ooops just saw this. Comment this line out also. /dev/vda1 /boot ext4 defaults 1 2 ... you now have this /home/boot which is included in your disk but was previously a partition.
reboot and choose this second kernel
WAIT..... just realized that grub.conf appears to be out of order... need to figure out last kernel you guys used.

Re: Restore from Backup
You are defaulting to the entry I chose but did you pick another kernel each time?

Re: Restore from Backup
Guess you could add 2 entries /boot/grub/grub.conf if you don't know why you had a newer kernel that wasn't the default.
This would give you a few options to try on reboot. I am thinking 20% it boots - What do you think of our chances? If it fails pick the first choice (what we have now) and we go back to the drawing board depending on the messages for the fail.

Re: Restore from Backup
I got a bit lost with your surge of posts... sorry...
so you want me to modify the /boot/grub/grub.confi and add these lines to it?
if yes, where do I put them? at the top?

I opened this file /boot/grub/grub.confi

and modified it to look like this... is that what you want?

Re: Restore from Backup
Put them below your current kernel entry... Each group is a kernel to boot from. We leave what you have so you can get back to this current configuration should it fail. The other 2 entries represent choices of kernels to pick on boot up.
Does that make sense? You can show me what you have by doing this after you are done if you are not sure:
