Database problem

My site has been running fine for months but I've not had need to login to the admin for about a month. I see the have been a great number of updates installed. I now have problems;

Can't list databases or database users either in root or user.
Can't add a new database

Also the backup is not backing up databases.

Hi driftwood,

Check your disc space, sounds like you don't have enough space.
Login in SSH and type df -h.

Yea maybe space in disc, if not maybe need see websites to biggest

you should have some error displayed so we could answer you correctly.
