Hi, this is my first mail here, so hi all :) i have corosync 1.3.3, openais 1.1.4 and lvm2 2.02.88, on top of gentoo. in lvm.conf i have locking_type = 3, and lvm2 were built with flag --with-cluster=corosync. corosync is started with "OPENAIS_SERVICES=yes". clvmd require corosync at start (otherwise refuse to setup properly) and when i make a `lvs` to list all volumes i can see correctly a shared AOE volume (vgAOE20), with c flag on it (clustered). i also see, with clvmd in debug mode, communications between nodes on lvs (log attached) but when i mount a volume in that vg, there is no communications between the nodes. any hints, faq, documentation, debug procedure to suggest?
That's quite correct, clvmd does not do device locking. When you activate a volume it will take out a (shared) lock on the device. What you do with the device after that is up to you. It doesn't have to be a filesyste, it could be a raw volume used for perhaps a database.
