85ac11b69b If the pre_command fails then go back and wait patiently for the next 
pre function rather than retrying it until we get stuck!

471ab92bbb Allow clvmd debug to be turned on in a running daemon using clvmd -d 
You can do with cluster-wide too, by adding -C

01fdf84d69 Remove system LV code from clvmd. It's never been used and never should be 
used! It's removal tidies a number of code paths inside clvmd.

f91aadbea8 Fix hang in clvmd if a pre-command failed. The pre/post thread was getting 
out of sync in this instance and would not quit.

b9ba9ffad2 clvmd ia64 alignment fixes etc. (pjc) 2006-12-01 23:10:26 +00:00

1cd8c849b8 Always compile debug logging into clvmd as it's too useful to 
restrict to just developers.
-d will switch it on and run the daemon in the foreground

d2b7cfa2d1 Add -T (startup timeout) switch to clvmd 2006-11-30 09:44:07 +00:00
Patrick Caulfield
4e2f240c98 Add clvmd call to return the cluster name. 2006-10-09 14:11:57 +00:00
Patrick Caulfield
8233cfd371 Vastly improve the errors returned to the user from clvmd. 
It now captures the error messages that are generated and returns them
in the reply packet rather than just telling the user to check syslog.
 2006-10-05 13:55:50 +00:00
Patrick Caulfield
f1604c3e69 Add -R switch to clvmd. 
This option will instruct all the clvmd daemons in the cluster to reload their device cache
 2006-10-04 08:22:16 +00:00

c561addc94 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.

7a8ea2ac93 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 ?

ca4e0c973a Log an error if clvmd can't resolve a host name got from CCS 
Fix potential spin loop in clvmd

8e526ba1bf Don't defer closing of FDs in clvmd as it can cause trouble. 2005-06-13 10:16:21 +00:00

901f7c5c36 Tidy clvmd's SIGHUP handler so it doesn't do all that work. 2005-04-19 10:36:42 +00:00
Patrick Caulfield
6102a5d2b0 Make clvmd work around some "limitations" in gulm's node state notifications. 
Also make clvmd debuglog timestamps a little more helpful.
 2005-04-13 13:50:07 +00:00

5ac1c69710 Don't allow user operations to start until the lvm thread is fully up. 
Hopefully finally nails bz#146056

701c05ce96 Tighten signal handlers. 2005-03-21 14:16:16 +00:00
Patrick Caulfield
b982232cc5 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
6a0dcd7f0e 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

6dba6cd78d 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

522db1bf01 Fix thread shutdown race which could cause clvmd to hang in pthread_join. 2005-02-08 09:05:58 +00:00
Patrick Caulfield
ee20fa97c2 Make clvmd announce it's startup and cluster connection in syslog. 2005-01-24 15:31:13 +00:00
Patrick Caulfield
32e175752c 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

5529aec0d6 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.

8b170dc2bf Fix off-by-one error in cluster_locking that could case read hangs. 2005-01-07 14:22:49 +00:00
Patrick Caulfield
86046445ed Improve clvmd failure message if it's already running. 
Allow user to kill clvmd during initialisation.

6f4e93dc90 Configure/makefile tidy. 2004-11-26 18:07:17 +00:00

2affe53727 Tidy the socket callbacks so that all the work is done outside the 
main loop.

20f3408d96 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
d48f8bf5cc 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
99d97754a6 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
e3ef54f99b 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

6533aa865a 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
953f4838dd Make the thread handling a little less cavalier. In particular, calling 
pthread_exit in a signal handler was a /really/ bad idea.

858a2b1b88 Add cluster support. 2004-06-24 08:02:38 +00:00
