[Linux-cluster] CLVM performance

[Andrew Holway]

Hello,

Ive been doing some testing.
I have an iSCSI device that I have set up with CLVM. 
I have 4 physical hosts, all with top of the range xeons and 144GB ram. 
I have 12 KVM machines per physical machine with a total of 48 VMs.
Each KVM is mounted on a LV.
The performance is not very good.
I am not a fish.

Could CLVM be the bottleneck? Especially with so many LV's?
I though I would ask before I set up 48 physical luns on the iSCSI device :)

Thanks,

Andrew
