fron 1 month I have always problems with my VPS. Before it was file system, it told Can't create/write to file '/tmp/ - error 30.
My host had fixed the problem but today tried to upgraded Webmin and now doesn't work more:

I tried to restart MySQL but now also MySQL is dead and I can't do backup of my database...
I can still connect via SSH and FTP to server.
Just I connect to SSH I have various errors:

How can at least I backup my database?? :( So I'll can reinstall all VPS.
I tried with: mysqldump -p -u userdb namedb > dbname.sql -bash: dbname.sql: Read-only file system
But nothing, server is in read-only mode now..I can't do something..
SQL Error: 2002 - No such file or directory
Query: [READ] Unable to connect to MySQL server
Thank you in advance and sorry for my bad English
