[Pacemaker] About the difference in handling of "sequential".
Hi All,
There is difference in two between handling of "sequential" of "resouce_set" of
colocation.
Is either one not a mistake?
static gboolean
unpack_colocation_set(xmlNode * set, int score, pe_working_set_t * data_set)
{
xmlNode *xml_rsc = NULL;
resource_t *with = NULL;
resource_t *resource = NULL;
const char *set_id = ID(set);
const char *role = crm_element_value(set, "role");
const char *sequential = crm_element_value(set, "sequential");
int local_score = score;
const char *score_s = crm_element_value(set, XML_RULE_ATTR_SCORE);
if (score_s) {
local_score = char2score(score_s);
}
/* When "sequential" is not set, "sequential" is treat as TRUE. */
if (sequential != NULL && crm_is_true(sequential) == FALSE) {
return TRUE;
(snip)
static gboolean
colocate_rsc_sets(const char *id, xmlNode * set1, xmlNode * set2, int score,
pe_working_set_t * data_set)
{
xmlNode *xml_rsc = NULL;
resource_t *rsc_1 = NULL;
resource_t *rsc_2 = NULL;
const char *role_1 = crm_element_value(set1, "role");
const char *role_2 = crm_element_value(set2, "role");
const char *sequential_1 = crm_element_value(set1, "sequential");
const char *sequential_2 = crm_element_value(set2, "sequential");
/* When "sequential" is not set, "sequential" is treat as FALSE. */
if (crm_is_true(sequential_1)) {
/* get the first one */
for (xml_rsc = __xml_first_child(set1); xml_rsc != NULL; xml_rsc =
__xml_next(xml_rsc)) {
if (crm_str_eq((const char *)xml_rsc->name, XML_TAG_RESOURCE_REF,
TRUE)) {
EXPAND_CONSTRAINT_IDREF(id, rsc_1, ID(xml_rsc));
break;
}
}
}
if (crm_is_true(sequential_2)) {
/* get the last one */
(snip)

Re: [Pacemaker] [Question:crmsh] About a setting method of seuquential=true in crmsh.
Hi Kristoffer,
Thank you for comments.
I tested it.
However, the problem seems to still occur.

I ended up attaching the trace to an existing bug listed in the CentOS bug tracker: http://bugs.centos.org/view.php?id=6853 This looks like something to do with clvmd and its locks, but dlm appears to be operating fine for me, I don't see any kern_stop flags for clvmd at all when the node is being fenced.

Re: [Pacemaker] resource is too active problem in a 2-node cluster
Yes, we have cman (version: cman-3.0.12.1-49). We use manual fencing ( I know it is not recommended). There is an external monitoring and fencing service that we use (our own). Perhaps subject line "resource is too active problem in a 2-node cluster" was misleading. Real problem is that resource is *NOT* too active, but pacemaker thinks it is. Which leads to undesirable recovery procedure. See log lines below Feb 04 11:27:38 [45167] gol-5-7-0pengine: warning: unpack_rsc_op: Processing failed op monitor for GOL-HA on gol-5-7-0: unknown error (1) Feb 04 11:27:38 [45167] gol-5-7-0pengine: warning: unpack_rsc_op: Processing failed op monitor for GOL-HA on gol-5-7-6: unknown error (1) Feb 04 11:27:38 [45167] gol-5-7-0pengine:error: native_create_actions: Resource GOL-HA (ocf::script.sh) is active on 2 nodes attempting recovery On 02/10/2014 09:43 PM, Digimer wrote: On 10/02/14 09:13 PM, Aggarwal, Ajay wrote: I have a 2 node cluster with no-quorum-policy=ignore. I call these nodes as node-0 and node-1. In addition, I have two cluster resources in a group; an IP-address and an OCF script. Turning off quorum on a 2-node cluster is fine, in fact, it's required. However, that makes stonith all the more important. Without stonith, in any cluster but in particualr on two node clusters, things will not work right. First and foremost; Configure stonith and test to make sure it works. Pacemaker version: 1.1.10 Corosync version: 1-4.1-15 OS: CentOS 6.4 With CentOS/RHEL 6, you need cman as well. Please be sure to also configure fence_pcmk in cluster.conf to "hook" it into pacemaker's real fencing.

[Pacemaker] display order in crm_mon output
Hi List, we've recovered a cluster after a failure and used a previously exported cib.xml. Everything is back to normal state. The strange thing is, that the order in the output of crm_mon is not like before. Can anyone bring some light into this please? What is affecting the order of the displayed ressources? Can we rearrange it somehow?
