so that we output the same list of keys in "catdb" as "tdbdump".
when traversing a persistent database, as an optimization, only
traverse on the local node (and thus skip checking if we are
dmaster or not). If the local node is not part of the vnnmap and thus
would not be guaranteed to have an uptodate persistent database
we instead traverse it on one of the other nodes that are in the vnnmap.

CTDB_SAMBA_SKIP_CONF_CHECK and CTDB_SAMBA_CHECK_PORTS.
The first is used to tell ctdb to no longer monitoring if the smb.conf file is consistent or not.
The second specifies which ports to check that smb is listening on
instead of using testparm to figure this out.
Since the net, testparm and smbstatus may block indefinitely in some configurations
we must have a way to configure ctdb to NOT use any of these three commands
in the scripts. These commands should thus never be used in scripts.

memory if ctdb_run_eventscript() would be called
during processing of ctdb_event_script_timeout() for
user unvoked eventscripts. (eventsccripts invoked by "ctdb eventscript ...")

address/name. To implement this stderr has redirected to stdout -
this doesn't need to be done but is the simplest implementation.
Remove -t option since it doesn't seem to accomplish much but causes
spurious messages to be displayed by ssh. Add explicit -h and --help
options. Make style of usage message consistent with documentation.
Document new features in doc/onnode.1.xml.

Do not assume all nodes are members of LVS so always deciding the recmaster will be lvsmaster wont work.
Instead,
Create the set of active LVS nodes as those nodes that are LVS capable and
also HEALTHY.
Except if ALL LVS capable nodes are unhealthy in which case we allow the unhealthy
nodes to be part of the active set.
In the active set, pick one of the active nodes as being the lvsmaster
which will receive all incoming traffic and distribute it across
the active lvs nodes in the cluster.

lvs: which shows which nodes are active LVS servers
lvsmaster: which shows which node is the lvs master multiplex node
pnn: which prints the pnn of the local node

when monitoring the node health.
this might be useful to skip for environments with thousands of shares

nfs should never stop spontaneously so trying to restart it is
just counterproductive and at best a workaround to
hide real bugs.

Kevin Collins noticed that RHEL5 grep-2.5.1-54.2.el5 built for
x86 does not handle \s while the exact same RHEL5 package for amd64
does!
[[:space:]] is more portable. Even across the same package version ( different architecture ) from the same vendor :-)

This reverts commit bfba5c7249eff8a10a43b53c1b89dd44b625fd10.
revert the waitpid changes. we need to waitpid for some childredn so should
refactor the approach completely

to "ping" the local nfs daemon.
Once it has failed more than 3 times in a row it will attempt to restart the nfs service.
(This used to be ctdb commit a4e89f57a8d733ea74df7b0de31eb977d6d37388)
so we should not call it from the main daemon.
1, set SIGCHLD to SIG_DFL to make sure we ignore this signal
2, get rid of all waitpid() calls
3, change reporting of event script status code from _exit()/waitpid() to write()/read() one byte across the pipe.

If the event script that timed out was for the "monitor" event, then
even if it timed out we still return SUCCESS back to the guy invoking the eventscript.
Only consider the eventscript for "monitor" to have failed with an error
IFF it actually terminated with an error, or if it timed out 5 times in a row and hung.
