No space left on device

Hi

I have getting error like below Warning: session_start() [function.session-start]: open(/home/snaturgold/domains/wearekrabi.com/tmp/sess_ea2eaffca6b8aa7768ea64d2b0df2727, O_RDWR) failed: No space left on device (28) in /home/snaturgold/domains/wearekrabi.com/public_html/header.php on line 2

I dont think my drives are full but when deleted some files it seems to be working again but eventhough i uploaded no new files, after a while the error came back. Since the server was a sub server, I tried converting it to parent server, now the website is inaccessible but the files are all there. I'll paste the info on the move below.

I read some posts that has the same errors and run some command so here is the result
