436cd05156 Fix unlocks in clvmd-corosync. 
The DLM unlock returns EUNLOCK in the lksb on success, not 0

fe3a28e2cc Fix possible increasing in memory allocation if refreshing_context 
(for example when CLVMD_CMD_LOCK_VG for is called during vgscan).

If clvmd calls LV lock, it calls
    /* clean the pool for another command */
	dm_pool_empty(cmd->mem);
to clean up memory pool after command.

Unfortunately, do_refresh_cache() do not call this
and because during it operation it allocates some memory,
the pool increases.

Also do_refresh_cache should use lvm_lock
(it manipulates with lvm internal data).

The same applies for lvm_backup command.

0296197999 Create global is_static() to eliminate from the library init function. 
Very simple / crude method of removing 'is_static' from initialization.
Why should we require an application tell us whether it is linked
statically or dynamically to libLVM?  If the application is linked
statically, but libraries exist and dlopen() calls succeed, why
do we care if it's statically linked?

c5c13fe776 Remove struct arg * from struct cmd_context and create_toolcontext(). 
This allows us to remove one argument from create_toolcontext() and
moves it closer to a generic library init function.

In the arg_*() functions, we just use _the_args() directly.
For now we leave the first parameter to these
arg_*() functions (struct cmd_context *) because
of the number of files involved in removing the
parameter.

f059ab7150 Remove redundant set_activation() call after create_toolcontext() calls. 
Very similar argument to removal of init_debug() and other calls.

create_toolcontext() calls _process_config() which sets
cmd->default_settings.activation, then calls
set_activation(cmd->default_settings.activation).  Later, create_toolcontext()
sets cmd->current_settings = cmd->default_settings.  So these calls
set_activation(cmd->current_settings.activation) are redundant.

a51b3f838d Remove backup_enable() calls after create_toolcontext() calls. 
Identical argument to previous patch which removed archive_enable() calls.
We add a new parameter to backup_init() which sets the enable value based
on the cmd->default_settings.backup value.  This value was used to set
cmd->current_settings.backup, used in the removed backup_enable() call.

4fa2c7f8b6 Remove archive_enable() calls after create_toolcontext() calls. 
_init_backup() calls archive_init(), which originally set 'enabled' to
a hardcoded '1' value.  This seems incorrect based on my read of other
areas of the code so here we add a 'enabled' paramter to archive_init().
We pass in cmd->default_settings.archive, which is obtained from the
config tree.  Later in create_toolcontext, cmd->current_settings is
set to cmd->default_settings.  The archive_enable() call we remove
here was using cmd->current_settings to set the 'archive' enable
value.  The final value of cmd->archive_params->enabled should thus
be equivalent to the original code.

6f4c0fb93d Remove init_verbose() calls immediately after create_toolcontext() calls. 
The rationale for removing init_verbose() call is very similar to removing
init_debug() call.  create_toolcontext() calls _init_logging() which
makes these calls:
        /* Verbose level for tty output */
        cmd->default_settings.verbose =
            find_config_tree_int(cmd, "log/verbose", DEFAULT_VERBOSE);
        init_verbose(cmd->default_settings.verbose + VERBOSE_BASE_LEVEL);

And being that create_toolcontext() copies default_settings into
current_settings at the bottom, the init_verbose() call we are removing:
        init_verbose(cmd->current_settings.verbose + VERBOSE_BASE_LEVEL);

is redundant.

fb19b83ff2 Remove init_debug() calls immediately after create_toolcontext() call. 
We can safely remove because create_toolcontext() calls _init_logging(),
which makes these calls:
        /* Debug level for log file output */
        cmd->default_settings.debug =
            find_config_tree_int(cmd, "log/level", DEFAULT_LOGLEVEL);
        init_debug(cmd->default_settings.debug);

Then at the bottom of create_toolcontext() we do this:
        cmd->current_settings = cmd->default_settings;

So the call we are removing from init_lvm() functions (clvmd and lvmcmdline):
        init_debug(cmd->current_settings.debug);

Just sets the value of debug based on 'cmd->current_settings.debug'.
Since cmd->current_settings is equivalent to cmd->default_settings, and
init_debug() was called with cmd->default_settings, the call we remove is
redundant.

746e7dc42e The attached patch is a try to make clvmd work correctly on openais stack. 
It does 2 things.

1. The cpg_deliver_callback make a compare between target_nodeid and our_nodeid.
It turns out openais set target_nodeid to 0 sometimes. for broadcasting ? I change the behavior so that lvm will process_remote also on target_nodeid == 0

2. The joined_list passed to cpg_confchg_callback doesn't include the already exist nodes in the group, which leads to an incomplete node_hash. I simply add all other nodes in member_list to node_hash also.

Thanks to Xinwei Hu for this patch.

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.

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=cman

When clvmd with both included is run, it will automatically detect the cluster
manager in use.
