[Linux-cluster] Using cmirror

Hi James and Brassow,

Thank you for the replies on using cmirror. I'll try the configuration
(below) on my test servers, and post the findings here.

Regards,
Bernard Chew

I had no problems creating such a setup.

Where I did have problems was when one of the iscsi disks "went away".
At that point the iscsi layer appeared to hang and lvm locked up :(

(You need three separate PVs to create a mirrored LVM volume, btw).
