Get clvmd to use libcman rather than cman ioctl calls. This makes
...
it forward-compatible with the new userland CMAN in cluster head.
To build it you will need the libcman header & library installed.

Don't send a signal to kill threads that are idling nicely as it upsets them.

This seems to cure bz#159727 on SMP systems.
Alasdair, can you include this patch in the lvm2-cluster package please ?

Also make clvmd debuglog timestamps a little more helpful.

Don't take out the lvm_thread_lock at startup - it only protects the jobs list.
...
DEBUGLOG() message now print threadid rather than PID which is more useful.

make clvmd FDs close-on-exec, to avoid warnings when running lvm via popen.

clvmd-gulm unlocks VG & orphan locks at startup in case they are stale.
clvmd-gulm now unlocks VG & orphan locks if client dies.

Cope with more than one message arriving at the TCP socket, also

fix some instances where the length in the message was wrong (cman
code didn't notice this because it is packet-based comms anyway)

Fix clvmd startup bug introduced in cman/gulm amalgamation. bz#145729

Improve reporting of node-specific locking errors so you'll get
somthing a little more helpfiul than "host is down" - it will now tell
you /which/ host it thinks is down.

You can now build clvmd with cman & gulm support in the same binary.
...
./configure --with-clvmd
wil do this by default. Or you can choose which you want with
./configure --with-clvmd=gulm or
./configure --with-clvmd=cman
When clvmd with both included is run, it will automatically detect the cluster
manager in use.

Revert the fork back to where it was as it seems to confuse pthreads.
...
Instead, the parent now waits for the daemon to signal that it has
completed successfully (or not) so it can return status to the user.
