I wanted to make a few comments. 1. The mount command basically just shows a prettified version of /etc/mtab. If your / partition has changed from rw to ro, that file is no longer current. You're better off doing 'cat /proc/mounts' to see for sure what is mounted where and with what status. 2. In this case, undoubtedly the kernel found something wrong with the filesystem and decided that to not totally screw things up, it just changed it to ro. The kernel dmesg ring buffer will have output about what happened that made the kernel choose to do that. Normally it would also be in /var/log/messages, but since / went read-only, syslog couldn't write to the logfile so it's not going to be there (unless by some miracle the customer also had remote logging enabled, but if he's a newbie, it's very unlikely). You've already had to reboot the machine so you've lost that dmesg buffer. 3. In my experience, when this happens, the drive or controller or cable is bad, but it's usually the drive. Regards...
