[ClusterLabs] Triggered assert at xml.c:594

[Patrick Zwahlen]

Replying to myself,

This seems to be related to the latest drbd RA (8.9.4+).

Still, is it something we should worry about ?

Regards!

Subject: [ClusterLabs] Triggered assert at xml.c:594

Hi,

Short:
I'm getting asserts in my logs and wonder if I should worry.

Long:
I'm Running a lab on CentOS 7.2:
  pacemaker-1.1.13-10.el7.x86_64
  corosync-2.3.4-7.el7_2.1.x86_64

Since my latest "yum update", I see the following errors in my logs:

Feb 13 15:22:54 san1.local crmd[1896]:    error: pcmkRegisterNode: Triggered assert at xml.c:594 : node->type == XML_ELEMENT_NODE

I see these logs during cluster start and when moving DRBD resources from one node to the other. Everything seems to work, though.

Strange thing is, I didn't update any pacemaker related RPMs:

Could the new kernel be the reason for those asserts ?

Thanks for your input on this one. - Patrick -
