all file system went suddenly Read Only
 

I am Working on a fedora server with cpanel,
suddenly all the file system become unwritable,
and when trying to run anything that write to files , i see this messages
"Read-only file system"

and of course there is no logging working for anything , Now i cant see any reason for the problem.

mount -l shows that all are r,w

what should i DO ?

and why did that happen from itself , does anybody faced something like that before ? could it be a hack ?

Do a 'df' to make sure your drive hasn't filled up!

Run dmesg, chances are the filesystem detected and error and went read-only to protect itself.
