[Pacemaker] Cannot create more than 27 multistate resources

[Colin Mason]

I have run into this issue with greater than 55 resources when using pcs-0.9.90-2.el6.centos.2.noarch.

The other workaround is to run the pcs command with --debug. Take the whole XML text that pcs is trying to run cibadmin with and place it into a text file. Now convert the cibadmin command from --xml-text (-X) to --xml-file (-x) and use the XML file you just created. Fixed.

I grabbed your debug file and did some tests and it looks like the issue is caused by earlier version of pcs (0.9.90 is affected) which try to pass the entire cib on the command line to cibadmin.  This has been fixed upstream (and should be built in the next release of RHEL/CentOS).

As a workaround, you can use the upstream sources here: 
https://github.com/feist/pcs (just run pcs from the directory that is cloned).

Thanks!
