Hi folks, probably not CentOS specific but any help appreciated:
One of our CentOS4 servers crashed and when checked there was a disk problem which turned out to be a faulty SATA cable on one of the RAID 1 drives. This was sorted and the server brought back up after the usual disk checks and all has been well for the last week. Today, however, I tried 'df -h' and got:
Filesystem Size Used Avail Use% Mounted on df: `': No such file or directory
I can't recall whether I tried the command just after the server was restarted (ie: whether this is a new problem) but any pointers towards possible causes/fixes would be appreciated.
Thanks
Hi folks, I actually managed to find a message in an old forum somewhere about a corrupt /etc/mtab file and how to fix it: cat /proc/mounts > /etc/mtab, but when I tried it I was informed that the filesystem was read only.
Further checks revealed lots of disk channel errors being logged so I guess the hard disk may be on the way out after all. I'll be on site with a spare tomorrow.

Are there problems with any other commands like mount, lsof or du? Do the contents of /etc/mtab match what mount is showing as mounted?
Is there anything in /var/log/messages ? Does "strace df -h" give any indication where the problem lies? Are you sure it's /bin/df you're running? Does the binary have the same size and md5sum as a working df on another machine with the same version of the coreutils package?
Will.
