Root Filesystem (/) Mounts as Read-only


Can someone tell me what did I do to my filesystem, and how I can get it back?

I am configuring a RHEL5 system and I had some file system problems, including superblock errors. I followed a correction found here Surviving Filesystem Failures

After many reboots and fsck executions, it still will not mount on boot to read-write. However now it will let me remount to read-write after boot.

My /etc/fstab looks like:

Quote:
LABEL=/boot /boot ext3 defaults 1 2
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
/dev/VolGroup00/LogVol01 swap swap defaults 0 0
/dev/VolGroup00/LogVol00 / ext3 defaults 1 2
/dev/VolGroup00/LogVol02 /usr ext3 defaults 1 2
/dev/VolGroup00/LogVol03 /tmp ext3 defaults 1 2
/dev/VolGroup00/LogVol04 /var ext3 defaults 1 2
/dev/VolGroup00/LogVol05 /home ext3 defaults 1 2
/dev/VolGroup00/LogVol06 /more ext3 defaults 1 2
Running the command cut /proc/mounts -f 2,3,4 -d " " gives me:
Quote:
/ rootfs rw
/ ext3 ro,data=ordered
/dev tmpfs rw
/proc proc rw
/sys sysfs rw
/dev/shm tmpfs rw
/dev/pts devpts rw
/usr ext3 rw,data=ordered
/tmp ext3 rw,data=ordered
/var ext3 rw,data=ordered
/home ext3 rw,data=ordered
/more ext3 rw,data=ordered
/misc autofs rw,fd=6,pgrp=3015,timeout=300,minproto=5,maxproto=5,indirect
/net autofs rw,fd=12,pgrp=3015,timeout=300,minproto=5,maxproto=5,indirect
Notice that the rootfs is mounted rw, but the next one is ro.

Doing df -h gives me:
Quote:
Filesystem Size Used Avail Use% Mounted on
/dev/VolGroup00/LogVol00
10G 1.1G 8.5G 11% /
/dev/sda3 10G 1.1G 8.5G 11% /boot
Notice that the /dev/sda3 and the /devVolGroup00/LogVol00 have the same information, which is suspicious. Also, I am missing my other Logical volumes. (They are mounted but they don't show up unless I do a df -h /dev/VolGroup00/LogVol02). I have a another RHEL5 box with a similar setup and these volumes are listed with a simple df -h.

Anybody have any ideas on what's going on?

Thanks for any advice,

Eric

Hi eric. Your post is very complete. If all first posts here were like yours.

This possibility is a long shot, but do you have hal working?
Can you reboot and init on runlevel 3 without hal and check again.

You can change your default runlevel by edit the default /etc/inittab
Code:
# Default runlevel.
id:3:initdefault:

Thanks, I appreciate for your response. I set to runlevel 3 and rebooted, haldaemon off and I get the same problem.

I also tried booting to single user and got an error that /usr/bin/id not found. I am trying other things. I am also wondering if I made a mistake in setting the superblock.
