2a7f7fc1c9 Vastly improve the errors returned to the user from clvmd.

Patrick Caulfield
13583874fc Add -R switch to clvmd.

Patrick Caulfield
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.
 2005-08-16 08:25:09 +00:00

Patrick Caulfield
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 ?

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

779b7713cf Tighten signal handlers. 2005-03-21 14:16:16 +00:00
Patrick Caulfield
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.
 2005-03-09 14:08:11 +00:00
Patrick Caulfield
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.
 2005-03-07 17:03:44 +00:00
Patrick Caulfield
eb3037ddbd Fix clvmd-gulm node up/down code so it actually works. 
clvmd-gulm now releases locks when shut down.
 2005-02-22 16:26:21 +00:00
Patrick Caulfield
a00bfcc8b2 ./configure --enable-debug now enables debugging code in clvmd 2005-02-21 15:58:06 +00:00
Patrick Caulfield
ce1aa2c3ff Always manipulate both locks in sync_lock() otherwise they get left 
hanging around and cause trouble.
 2005-02-21 14:36:09 +00:00
Patrick Caulfield
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)
 2005-02-18 15:31:32 +00:00

65c591696a Fix gulm->errno error number conversion. 2005-02-17 12:56:19 +00:00

ceda2b1426 Fix thread shutdown race which could cause clvmd to hang in pthread_join. 2005-02-08 09:05:58 +00:00
Patrick Caulfield
5937664052 Revert last clvmd patch. More testing reveals that this just doesn't 
work yet.
 2005-02-07 14:45:38 +00:00
Patrick Caulfield
2cf7b80d8f Make clvmd use the command library rather than popen() to 
preload the lock state.
 2005-02-07 10:04:27 +00:00
Patrick Caulfield
d9656543ee Make clvmd do a quick sanity check on the clustering bits of lvm.conf 2005-02-02 11:42:29 +00:00

Patrick Caulfield
4e224cf079 Remove superflous & 
Gulm clvmd no longer hangs trying to talk to a rebooted node.

Patrick Caulfield
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.
 2005-01-21 11:35:24 +00:00
Alasdair Kergon
5d0b9f475a fix clvmd lv_info_by_lvid open_count 2005-01-19 18:10:09 +00:00
Patrick Caulfield
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.
 2005-01-13 13:24:02 +00:00

a057a834b7 Use new CCS key names for nodes in the GULM version of clvmd. 
based on a patch from Mike Tilstra

a266258f4c Configure/makefile tidy. 2004-11-26 18:07:17 +00:00
Patrick Caulfield
bb7b7c6d5f Tidy the socket callbacks so that all the work is done outside the 
main loop.
 2004-11-16 10:55:01 +00:00

badd6fb7ba Report detailed errors in cluster initialisation to syslog, and point the user 
at syslog if clvmd fails to intialise.
 2004-11-11 14:51:23 +00:00
Patrick Caulfield
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.
 2004-11-03 10:45:07 +00:00
Patrick Caulfield
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).
 2004-10-06 12:36:47 +00:00
Patrick Caulfield
bfd4b01407 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.
 2004-10-06 10:12:34 +00:00
Patrick Caulfield
8d81a737a4 Change some perror() calls to log_error() so they'll appear in 
syslog when we're a daemon.
 2004-10-06 10:02:25 +00:00
Patrick Caulfield
e5011ba8bf Check the UUID length when readingthe output of the "lvs" command at startup. 
This way we should not get quite so confused by any debugging output
that may come our way.
 2004-10-04 09:23:52 +00:00
Patrick Caulfield
cf54177475 Make clvmd cope with large gaps in nodeIDs 2004-09-30 14:18:29 +00:00
Patrick Caulfield
896318f475 Fork a little later in the startup sequence so that we can return 
an error code if the cluster infrastructure isn't there.
 2004-09-30 14:16:28 +00:00
Patrick Caulfield
8ef0b7b9ef Keep client locks (VG locks usually) in their own hash table so 
we can actually have more then one of them per client.
 2004-09-24 09:39:57 +00:00
Patrick Caulfield
985f52fe34 Make the thread handling a little less cavalier. In particular, calling 
pthread_exit in a signal handler was a /really/ bad idea.
 2004-09-23 12:51:56 +00:00
Patrick Caulfield
421bb2e9bf Don't use hold_lock for VG locks as that doesn't stop processes contending 
on the same node, only across the cluster.
 2004-09-23 12:29:35 +00:00
Patrick Caulfield
56942c3f2a Put some locking round the LV hash table as it could be accessed by 
different threads concurrently.
