It crashes when I activate dmeventd for both snapshots and non-snapshots
--- i.e. place this into lvm.conf:
dmeventd {
mirror_library = "libdevmapper-event-lvm2mirror.so"
snapshot_library = "libdevmapper-event-lvm2snapshot.so"
}
and then activate the volume group with both snapshots and mirrors with
vgchange -ay and vgchange -an.
When I activate volumes one-by-one with lvchange, it is somehow more
stable.
