[Linux-cluster] falied to implement HA-LVM with clvmd rhcs5.6

[Dominic Geevarghese]

Hi,

I am not sure about the error you are getting but it would be great if you
could try the preferred method

locking_type = 1
volume_list [ "your-root-vg-name" , "@hostname" ]

rebuild initrd

add the <lvm> and <fs> resources in cluster.conf , start the cman, rgmanager
.


Thanks,
