phobos13013,

Your root is /dev/sda5 - no LVM is in use.
As krinn says, try booting a liveCD/USB and running fsck on /dev/sda5.

root is checked to be clean every boot and fixed if possible.

Keep a backup of /home before you run fsck, since fsck can make a bad situation worse.
All it does is make the filesystem data structures on disk self consistent.
That says nothing about any user data that may be on the filesystem.
/home is where your user data is. Everything else can be recreated.

If you want to be a bit more adventureous, you can try to remount root using a backup superblock.
If a corrupt primary superblock is the issue, this will fix it. If not you will still see the error in dmesg.

Code:
man mount
find the options for ext2, they apply to ext4 too.
See the sb=n entry.

Hello all! Sorry for the delay in response but I was called out of town unexpectedly and was not able to attend to this until today. But during the time away it gave me lots of opportunity to think about the issue. In addition, I can confirm NeddySeagoon you did it again; you are the finest of all Scots (no true Scotsman my ARSE!). I kid!

But seriously folks, I did an e2fsck on the disk unmounted and it found innumerable issues. Not sure if its a drive thats on the way out (it is super old), or if its that filemanager i was using to shuffle lots of files around, but anyway, I went the simple route and just did e2fsck since I didnt want to invest any more time into the superblock method and luckily it fixed all isues with no apparent irreprable harm to the fs. that said I did save /home just in case.

Consider this HAPPILY CLOSED!
