We have 5 Dell server collocated running CentOS 4.x and 5.x server operating system. Sometime my file system (ext3) goes read-only. I’d like to know what could be causing such a problem?

Sometime by mistakes all file permissions get changed and you need to restore file permission. For example a shell script or some sort of corruption could change the permissions for packages (installed files), it may be necessary to reset them.

For example a long time ago my shell script run chmod and chown commands on /usr and changed the permission. Luckily rpm command can reset package permission. Sun Solaris pkg command and IBM can also reset permissions.
