This sounds like your /dev directory went bad. I don't know what version of Linux you are running. Does it use udev? Did udev fail to start?
-----Original Message----- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of Joell Chockley Sent: Monday, January 14, 2008 6:54 AM To: [email protected] Subject: Linux not recognizing file systems I've got a strange problem with a Linux guest. The only indicator we've come up with so far is that /dev/null had it's file permissions changed on Friday afternoon to -rw-r--r-- 1 root root 81 2008-01-11 15:03 /dev/null (we don't know how this was changed). One of our admins changed it back to 666, but it was still missing the character file attributes. Everything still worked fine, until it was rebooted on Sunday evening. Now, it comes up under VM, but the connections that allow us to putty to it aren't working. It's only mounting / and when I sign on as root and try to change null to a character file, it tells me the file system is read-only although the permissions for /dev are drwxr-xr-x. It's also not mounting /opt which is what is on /dev/system/lvm1. doing the mount command, we see this output. proc on /proc type proc (rw) (none):/ # mount -a mount -a mount: devpts already mounted or /dev/pts busy mount: /dev/system/lvm1 is not a valid block device We're in the process of trying to restore back to the last good full volume backup, but I'm really curious if changing /dev/null could have this strong of a impact and if there's any ideas of what we might be able to do to fix the problem without restoring.
