fsck.ext3: No such file or directory while trying to open /dev/dm-1 [FAILED]

I was mucking around with my Storwize V7000 storage array that was connected to my Red Hat Linux server. Then I went back to my Red Hat server and started configuring couple of applications on it, and then rebooted the machine.

The boot process stopped, and I got the message:

Checking filesystems
fsck.ext3: No such file or directory while trying to open /dev/dm-1 [FAILED]
*** An error occurred during the file system check.
*** Dropping you to a shell; the system will reboot
*** when you leave the shell.
Give root password for maintainance
(or type Control-D to continue):

I realised  that in the processing of mucking around with the storage I had removed then volume(LUN) that I had created, and then mapped onto the Red Hat server. I had then created a ext3 file system on that volume.

It was this volume(LUN) that the boot process was complaining about.

To fix the issue, I logged into the machine in single user mode with my root password. The fix is rather straight forward, uncomment the mount point line in the /etc/fstab file.

You will see that you won't be able to do that, so what you need to do is mount / in read write mode.

#  mount -o remount,rw /

# vi /etc/fstab

comment out the line, and then reboot the machine. There you go, it's fixed!!!
