We use an mdadm raid-config consisting of 4 or more SSD's/Disks where we use part of the disks for a raid1,raid10 or raid5. We create volumes on 2 nodes and use DRBD to keep these 2 volumes in sync and we run a virtual machine (using KVM) on this volume.
I've used DRBD for an almost identical setup, except only raid1 - we were even cheaper that you. :-> I would first suspect DRBD hanging - and you should check the queue stats to see if there is a backlog. If you are using the paid version with a userland smart buffering process, check whether that has died. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
