Well yes you have a lot of RTFM to do.

This setup looks very wrong and there is a lot of work on the storage
side you need to do.

I am not even sure where to start, but a few simple points:

1) you need to use proper shared storage. AOE is fine, but use the real
one. not 2 local disks exported, because that's never going to work.

2) if you want to use clvmd, all nodes *must* see the same storage

3) you need a cluster filesystem such as GFS2. ext3 and reiserfs are not
cluster fs. If you mounted any of those on both nodes, I strongly
recommend recreateing the fs and restore data from a backup.
