Fix Cisco LMS Filesystem Errors

We have in the past run into problem where our Cisco LMS 4.2 would not boot after a crash or power outage.  This problem is due to filesystem errors and inconsistencies due to an ungraceful shutdown.  We run ours in a VM guest. Here is how to fix this problem:

• Power off the Cisco LMS VM guest
• Add the disk from the LMS VM to a Linux (either Ubuntu or Debian) VM
• Login to the Linux VM and run the following to add LVM support

1. modprobe dm-mod
2. vgchange -ay
3. lvscan
4. lvscan | grep ACTIVE |awk -F”‘” ‘{print “fsck -t ext3 -y “$2}’ | sh

This will fsck every volume and clean any errors.  After it is finished:

• Remove the LMS VM disk from the Linux VM
• Power on the Cisco LMS VM

That should be it.
