Thanks I looked up the issue and found that the hard drive could be dying I have a backup and am running one now is there any way to see if the backup has started?
Which backup method did you use?
The server is using a single disk image
And no backups? Oh lord....
You are almost certainly going to lose data with those read errors. Your backup may not complete, and if it does data may be lost.
One thing you might try if the backup doesn't complete properly is to try a backup of configs only. You can then build a new server, restore the configuration, and copy over whatever data you can get.
There is info on the wiki how to do it.
There is possibly another method but we'll leave that for now.
In the meantime go and buy a pair of drives and run a mirror at least. That gives you one level of protection. Backup regularly for a second, and don't use just one backup disk... get a couple and rotate them so you always keep one good one.
Might seem expensive, but then how much is this disaster going to cost you?
Keep us posted so we can help if possible.
