Default Re: Waiting for /dev/sda2 to appear

subman,

thois problem might be related to the disk device names.
sd<x> indicates scsi disk number x in your system.

The linux system has configured in the /etc/fstab which filesystems should be mounted at boot time. They might not be defined there as sd<x> in newer linux versions. It was found that sd device make problems especially in SAN environments and therefor the fstab was changed to use the /dev/disk/by-id names of the disks. This new names are now hardware dependent because they contain the id that is read from the physical disk. In your case you might have taken the image from one system and deployed it to a different one, now those by-id devices do not match anymore and the mounts in fstab cannot be done.

To check that, you can boot the restoired image with a rescue system, mount the root partition that might contain the /etc folder and check the fstab. If you have there the by-id deviecs, you can chnage to the correct ones on this hardware or change back to the sd<x> names.
