(but io errors indicate something more serious - what exactly it says?) Whatever, seems you are doing several mistakes, lets try this: /dev/sda5 is LUKS device for sure, you have to first activate: 1) cryptsetup luksOpen /dev/sda5 sda5_crypt does it work and device is properly unlocked? If so, then 2) please paste output of: "blkid /dev/mapper/sda5_crypt" I guess it will be LVM PV. If so then run 3) vgscan ; vgchange -a y 4) paste here output of "blkid /dev/mapper/*" Maybe you can add also "blkid /dev/sd*" so we can be sure what's type of partitions you have there - the grub entry you mentioned does not match the device on /dev/sda5. (I would say paste here output of "lsblk -f" but this command is not yet in CentOS5.)
