When using volumes in clustered volume groups, there is a need to convert
cluster locks between shared and exclusive.
Shared lock is needed to be able to perform live VM migration,
exclusive lock is needed to take LV shapshot (and just for safety).
Also, to use clvm as a locking mechanism for libvirt/qemu, there is a need to
be able to perform LV lock conversion on a remote node (because last phase
of live VM migration, when 'source' qemu process is actually killed and LV
becomes not opened, is performed on a migration source node and there is no
event available on a destination node to do local shared->exclusive conversion).
Vladislav Bogdanov (10):
lvchange: Allow cluster lock conversion
clvmd: Fix buffer size
clvmd: Allow node names to be obtained from corosync's CMAP
clvmd: fix positive return value is not an error in csid->name
translation
clvmd: use correct flags for local command execution
clvmd: additional debugging - print message bodies
locking: Allow lock management (activation, deactivation, conversion)
on a remote nodes
lvchange: implement remote lock management
man: document --force option to lvchange, provide examples
man: document --node option to lvchange
