Florian + Dejan,
here the version with terse output. The code got terser as well.
It looks good, just a few notes. The check function should move
to the CibObjectSetRaw class and be invoked from
semantic_check(). There's
rc1 = set_obj_verify.verify()
if user_prefs.check_frequency != never:
rc2 = set_obj_semantic.semantic_check()
The last should be changed to:
rc2 = set_obj_semantic.semantic_check(set_obj_verify)
set_obj_verify always contains all CIB elements (well, that means
that its name should probably be changed too :). Now, the code
should check _only_ new and changed primitives which are
contained in set_obj_semantic. That's because we don't want to
repeatedly print warnings for all objects on commit, but only for
those which were added/changed in the meantime. On the other
hand, verify is an explicit check and in that case the whole CIB
is always verified.

[Pacemaker] restart only a particular service in group if it fails
Hi, I have setup a group where in , it has many resources configured say res1 , res2 , res3 , res4 , res5. To test if monitor is working or not, I stopped manually the res2 service When monitor command found res2 is stopped , it stops res3 , res4 and res5 and then tries to start res2. After it successfully start res2 , it then starts res3 , res4 and res5. My question is , Is it possible to just start res2 only without stopping other services that follows the resource(res3 , res4 , res5) which has been stopped.

It was much better and more thorough in testing than the other shell ra ldap link I found. That would be the first python RA. BTW, there was recently posted slapd RA (implemented in shell), which I should review, but haven't done that yet. /At any rate, that RA does not support multi-state resources which I think would be essential. Did you plan to do that? At any rate, I'd suggest that you check that code too and then see if you need to do your own implementation. The thread starts here: http://marc.info/?l=linux-ha-devm=129666245428850w=2 Great stuff and very thorough. But it doesn't look like it will work in our config because the files won't exist on the DRBD slave. I will use this as my new example. I'm not sure what you are referring to with multi-state resources. Is this in relation to promote,demote, migrate_to, migrate_from in the guide, i.e. master vs slave or is there more to it? I plan to support a master and slave later on down the road -- under pressure to get this rolled out now. Is there a good discussion / resource other than the dev guide? I had planned to try to wade through the DRBD RA scripts to figure it out. migrate_to/from are for something else. It's just promote (slave-master) and demote (master-slave). Why python? Because shell is harder for me to read and I have to make a good clear verbose example for some others who will also be doing some RA's (in python) for our custom apps. No problem with python. Actually, there was an idea to provide a python class (RA or so) which would make implementing resource agents easier. The config file for OpenLDAP is stored in /etc/ldap/slapd.d/cn=config.ldif. This is on a DRBD active-passive system and the /etc/ldap directory is actually a symlink to the DRBD controlled share /vcoreshare/etc/ldap. The real config file is at /vcoreshare/etc/ldap/slapd.d/cn=config.ldif. What about the old style configuration? I assume that there are still quite a few installations/distributions using those. Yes, I have some code for that, using the example slapd init script and the other examples I found, but no test environment for that. IIRC, the old configuration style is quite easy to parse. So I'm trying to be very judicious with every function and validation, checking file permissions, etc. But the problem is that /etc/ldap/slapd.d/cn=config.ldif is only present on the active DRBD node. My validate function checks that the file is readable by the user/group that slapd is to run as. Now, as soon as I start ldap in the cluster, it starts fine, but validate fails on the standby node (because the DRBD volume isn't mounted) and crm_mon shows a failed action: On probes (monitor with interval 0), some parts of validation which concern the local node and not the configuration should say OCF_NOT_RUNNING instead of error. This is exactly that case. No worries, because if the next action is start validation is invoked again. Probes are issued by pacemaker to establish if the resource is running and normally it is expected to be not running (for instance on node startup). Ah! I have a function that checks for probes but wasn't using it because I didn't quite understand the semantics. OK, hope that it's clear now.

rc2 = set_obj_semantic.semantic_check(set_obj_verify)
set_obj_verify always contains all CIB elements (well, that means
that its name should probably be changed too :). Now, the code
should check _only_ new and changed primitives which are
contained in set_obj_semantic. That's because we don't want to
repeatedly print warnings for all objects on commit, but only for
those which were added/changed in the meantime. On the other
hand, verify is an explicit check and in that case the whole CIB
is always verified.
+ra_class = prim.getAttribute(class)
+ra_provider = prim.getAttribute(provider)
+ra_type = prim.getAttribute(type)
+ra_id = prim.getAttribute(id)
+
+ra = RAInfo(ra_class, ra_type, ra_provider)
There's a convenience function get_ra(node) for this.
I did not use this as I need all ra_XXX value anyhow later in the code
for building k.
+if ra == None:
+return
+ra_params = ra.params()
+
+attributes = prim.getElementsByTagName(instance_attributes)
+if len(attributes) == 0:
+return
+
+for p in attributes[0].getElementsByTagName(nvpair):
+name = p.getAttribute(name)
+if ra_params[ name ]['unique'] == '1':
+value = p.getAttribute(value)
+k = (ra_class, ra_provider, ra_type, name, value)
+try:
+clash_dict[k].append(ra_id)
+except:
+clash_dict[k] = [ra_id]
+return
+
+clash_dict = {}
+for p in cib_factory.mkobj_list(xml,type:primitive):
This would become:
for p in all_obj_list: # passed from _verify()
if is_primitive(p.node):
+process_primitive(p.node, clash_dict)
Or perhaps to loop through self.obj_list and build clash_dict
against all elements? Otherwise, you'll need to skip elements
which don't pass the check but are not new/changed (in
self.obj_list).
The typical occurrences of clashes will originate from old objects and
new/changed objects.
I think I have to loop over all objects to build clash dict and
then ...
+
+no_clash = 1
+for param, resources in clash_dict.items():
+if len(resources) 1:
... only emit a warning if the intersection of a clash set with
changed objects is not empty.
+no_clash = 0
+msg = 'Resources %s violate uniqueness for parameter %s:
%s' %\
+(,.join(sorted(resources)), param[3], param[4])
+common_warning(msg)
+
+return no_clash
+
I will submit an updated version later this week.

Install that package and this should help. And there is no e2fsprogs-libs-devel for that distro (package naming scheme seems to be broken in this particular case).
