bc1024812a Replicator: check open_count for parents of presuspend_node
For deactivation of Replicator check in advance that all heads
have open_count == 0. For this presuspend_node is used as all
head nodes are linking this control node.

451be927a8 Replicator: support deactivate of replicator-dev nodes
Introducing dm_tree_node_set_presuspend_node() for presuspending child
node (i.e. replicator control target) before deactivation of parent node
(i.e. replicator-dev target).

This patch presents no functional change to current dtree - only
replicator target currently sets presuspend node for dev nodes.

874d697f4c API change for args of process_each_lv_in_vg()
Patch adds failed_lvnames to the list of parameters for process_each_lv_in_vg().
If the list is not NULL it will be filled with LV names of failing LVs
during function execution.

Application could later reiterate only on failed LVs.

d3ce80e544 Add lvm2app interfaces to lookup a vgname from a pvid and pvname.
lvm2app forces applications to start with a volume group name,
open the volume group, then operate on individual pvs.  In some
cases the application may want to start with a device name rather
than the volume group name.  Today, if an application wants to
do this, it must iterate through all the volume groups to find
the volume group that the specific device is attached to.
These new interfaces allow the application to avoid such overhead.
Bump the lvm2app version number to 3.

ea956b4f6c Update pvchange to always obtain a vg handle for each pv to process.
Earlier patches added some infrastructure to lookup a vgname from
a pvname.  We now can cleanup some of the pvchange and other code
by requiring callers that want to modify some pv property:
1) lookup the vgname by the pvname
2) use the vgname to obtain a vg handle
3) get the pv handle from the vg handle

This should work going forward and be a much cleaner interface,
as we move away from pvs as standalone objects.

ada4c61860 Add find_vgname_from_{pvname|pvid} functions.
Some commands start with a pvname, but we'd like to force users to
start with a vg handle to obtain a pv handle.  Our best option seems
to be providing a way to look up the vgname from the pvname, and then
require them to use vg_read/vg_open.

In addition to the pvname lookup function, this patch also provides a
lookup by pvid.  The lookup by pvid can be used in conjunction with
lvmcache_get_pvids to process all pvs in the system.

The pvid find function first calls lvmcache_vgname_from_pvid, which may
cause the label to be read if it is not in the cache.  If the vgname is
returned is an orphan, we then check to see if there are metadata areas,
and if not, we scan every PV on the system by calling scan_vgs_for_pvs().
In most cases we should not need to do this, and by using the info->mdas
count, we avoid calling pv_read() as prior code did.  So this patch is a
bit cleaner and should allow us to refactor more of the pv code.

0d272a6964 Disallow toggling the cluster attribute of a volume group if there
are active mirrors or snapshots.

We don't have the mechanisms in place to change the device-mapper
tables for those targets that have behavioral differences between
cluster and single machine instances.  Allowing users to change
the attribute but not changing the target's behavior can lead to
data corruption.

The following bugs are fixed/avoided by this patch:
235123 - vgchange -c [ny] do not change target types when necessary
289331 - RFE: switching from cluster domain to local domain needs to deactivate volume somehow
289541 - when changing from local to cluster, volumes can not appear to be deactivated

5ee39f1a1d Currently if clvmd is running and user issues vgscan,
the device cache file is dumped both in vgscan and clvmd process.

Unfortunately, clvmd calls lvmcache_label_scan,
it properly destroys persistent filter, but during
persistent_filter_dump it merges old cache content back!

This causes that change in filters is not properly propagated
into device cache after vgscan on cluster.
(Only new devices are added.)

1ad6e72ade Revert the "repeat failed tests with -vvvv" feature. Instead, dump debug logs
to a file using log/file, with log/overwrite set and dump this file in
STACKTRACE. The overall effect is that only the command that ran last before
the failure has been triggered will get its debug output logged. This is
similar to how we treat coredumps.

d7eaafe9c1 A fairly extensive refactor of the mirror testing code. The exhaustive
lvconvert testing is now in its own test, t-lvconvert-mirror-basic ... it
doesn't do anything fancy but it does run lvconvert through a lot of
combinations.

I have also merged the remaining t-mirror-lvconvert tests into
t-lvconvert-mirror and abolished the former. The latter will be split again
later into more thematic divisions. (The previous split was rather arbitrary,
may I even say random...)
