Hi,
I have cluster setup with 4 nodes and a FC-SAN Shared storage with LVM, which was working perfect for 2 years. We have 29 VMs, all KVM (7 windows 2008 r2 server, 3 windows 2003 server and the rest of them are debian).Yesterday I upgraded the nodes. Then most of the VMs started to show high loads and 3 of them froze with %100 load(debian). Stopping and then starting VMs solve the freeze issue but they froze again and again after working 10-15 mins. These VMs have very very low load and usually idle most of the time.
Booting the nodes with 2.6.32-4-pve kernel solved the problems immediately.
