31672ff60e Stop clvmd from automatically doing lock conversions. Now, if a lock
is granted at one mode and an attempt to convert it wthout the LCK_CONVERT
flag set then it will return errno=EBUSY.

This fixes a pretty bad bug in which an LV could be activated exclusively on
one node and lvchange -ay on another would convert it to shared!

It might break some things in other areas, but I doubt it.

115d48497e Add daemons/cmirrord files to git - somehow got messed up with cvs rename.
When clogd was renamed to cmirrord, somehow git got the remove of the old
files but not the add of the new files.  This patch adds the new files.

827480b9d6 Add some code to clvmd to look in the corosync confdb to see what cluster
interface it should be using, it can still be overriden with -I.

If corosync isn't running or there is no information then the usual
checking will happen.

This code only builds if corosync is available.

9dd273626a Cluster log daemon (clogd): use LVM bitops in place of ext2 bitops
Eliminate dependency on outside library, since the same functionality
exists in our tree.

[It is important that the bitops work in the same way, as the bitmaps
must remain backwards compatible.  I haven't tested every architecture,
but the x86* archs work.  My test involved using the old ext2fsprogs
bitops, memcpy'ing the bits over to the LVM bitset array and ensuring
that only the bits set via the old methods were set.]

cecc0e9dc8 Fix locking in clvmd
The changes to remove LCK_NONBLOCK from the LVM locks broke clvmd because the
code was clearly wrong but working anyway! The constant was being masked rather
than the variable that was supposed to match against it.

3f76b672f2 Making adjustments to go along with the changes to the kernel.
A patch to the kernel, adding the 'luid' field to dm_ulog_request,
will allow us to properly identify log instances.  We will now
be able to definitively identify which logs are to be removed/
suspended/resumed.  This replaces the old faulty behavior of
assuming the logs were the same if they had the same UUID and
incrementing/decrementing a reference count.

31b3571d31 Change exit() to _exit() in the child process. exit flushes stdio file buffers,
_exit doesn't. If there were some open files, an error in exec and subsequent
exit() would cause the buffers to be flushed twice.

Example:

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/wait.h>

int main()
{
	printf("buu");
	if (!fork()) {
		execl("/bin/true-not-exists", "/bin/true", NULL);
		exit(1);
	}
	wait(NULL);
	return 0;
}

for now.

It replaces bad behaviour in one set of circumstances with bad behaviour
in a different set.  We think the behaviour needs to be more configurable.

ba856910e0 Add infrastructure for queriying for remote locks.
Current code, when need to ensure that volume is not
active on remote node, it need to try to exclusive
activate volume.

Patch adds simple clvmd command which queries all nodes
for lock for given resource.

The lock type is returned in reply in text.

(But code currently uses CR and EX modes only.)

86b4b128a9 Use lvconvert --repair in dmeventd DSO (mornfall)
This means two things:

1) Non-mirrored LVs will be no longer affected by mirror monitoring. (Before,
if you had a LV that went partially missing on a VG where a mirror leg failed,
this LV would be removed automatically by dmeventd... Probably not an
unrecoverable dataloss bug, but still quite unpleasant.)

2) If enough parallel PV space is available at the time of the mirror failure,
the failed devices will be automatically replaced using this spare space. Which
(and whether) free space may be used is still not configurable, but is a
planned feature. Since it is relatively easy to undo the action by converting
the mirror manually, I don't consider this to be a showstopper. In fact, I
think the compromise is much better than what we have now.

d57543b220 Introduce lvm2_install target.
Buildsystem support device-mapper only install,
but generic install tagret includes both dm+lvm2.

For distribution which uses separate install_device-mapper,
there is no way how to install lvm2 only
(so after installing lvm2 for packaging purposes
built system must remove installed device-mapper files).

Fix it by allowing lvm2_install target, similarily like
install_cluster for clvmd.

(install = install_device-mapper + install_lvm2)
