Using lvm only on specific drives (Reading all physical volumes. This may take a while…)

July 1st, 2009
On our kvm hypervisor we have several vm’s using fibre channel for storage. The hypervisor has to see all the devices, but each device has it’s own lvm so when the hypervisor boots, it tries to read all of them. Read the rest of this entry »
