Disk Full || Help needed

[banditti]

I show my disk as being full. I don't know where though. It happened when one of my NFS mounts went offline. When it came back up, my local disk was at 100%

10.04 64bit server, no GUI


root@FlexBack:~# df -Th

Thank you in advance!

The response to your df command shows -
/dev/mapper/FlexBack-root ext4 14G 14G 0 100% /

Could you possibly boot up with a live CD and check what the dev/mapper/FlexBack-root contains?

[banditti]

That would be hard, it is a production system.

If you had another partition unmounted and performed a backup that would normally go to that device the backup may have ended up in the / mountpoint. The the contents of the mountpoint contents with the external unmounted.
