70ca1c94f1 Make sure it compiles if gulm is NOT selected AND using an old libcman.h 2006-03-15 08:36:11 +00:00

e7f55bb4c0 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.

fe6c78629d clvmd no longer takes out locks for non-clusteed LVs, 
and non-clustered LVs are only activated on the local node.

4bb7474e8a 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 ?

2b7e4013cd Make clvmd work around some "limitations" in gulm's node state notifications. 
Also make clvmd debuglog timestamps a little more helpful.

a6c23d8b8b 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.

3329bbfdf3 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.

ce1aa2c3ff Always manipulate both locks in sync_lock() otherwise they get left 
hanging around and cause trouble.

c9808c329d 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)

work yet.

2cf7b80d8f Make clvmd use the command library rather than popen() to 
preload the lock state.

6f4d25ec7f 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.

5c7fc7c4f7 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.

b1098701ec Can now build a gulm version of clvmd instead of a cman one. use 
./configure --with-clvmd=gulm

The default is still cman, and you can't have both - sorry.

3d4159b6bf Make clvmd -V display the lvm version number too rather than just 
the protocol version (which is not that useful and doesn't change very often).
