Description Ryan O'Hara 2014-06-06 13:58:40 UTC 
The 'clustercheck' helper script should read all variables from /etc/sysconfig/clustercheck. This file contains information required to check mariadb-galera cluster state, such as username, password, port, etc. If clustercheck cannot read variables from /etc/sysconfig/culstercheck, it will use default values which will almost certainly fail.

Running clustercheck on RHOS-5.0, RHEL-6.5 currently gives:

# clustercheck
HTTP/1.1 503 Service Unavailable
Content-Type: text/plain
Connection: close
Content-Length: 44

Percona XtraDB Cluster Node is not synced.

In this particular case this is wrong. The node is an synced member of the mariadb-galera cluster. The expected result is:

# clustercheck 
HTTP/1.1 200 OK
Content-Type: text/plain
Connection: close
Content-Length: 40

Percona XtraDB Cluster Node is synced.

Using 'bash -x' to run clustercheck makes the undelying mysql command visible, and clearly shows that the default values are being used, not the values in /etc/sysconfig/cluster.
Comment 1 Ryan O'Hara 2014-06-06 14:03:10 UTC 
I actually fixed this upstream a while back:

https://github.com/rohara/percona-clustercheck/commit/d0f366eeb91b72aaf022342b886062366a4e5f63

But it never got pulled into a RHOS-5.0 build. Easy fix, just requires rebuild.
Comment 2 Ryan O'Hara 2014-06-06 21:52:29 UTC 
The clustercheck script in rhos-5.0-rhel-7 branch is already up to date. This bug only exists in rhos-5.0-rhel-6 branch.
