2019-04-05T13:48:10.596570+02:00 sles12cluster1 IPaddr2(admin_addr)[5003]: ERROR: Interface label [eth0:testtesttest] exceeds maximum character limit of 15
2019-04-05T13:48:10.602892+02:00 sles12cluster1 lrmd[1281]:   notice: admin_addr_monitor_10000:5003:stderr [ ocf-exit-reason:Interface label [eth0:testtesttest] exceeds maximum character limit of 15 ]

From /usr/lib/ocf/resource.d/heartbeat/IPaddr2:

The kernel allows alphanumeric labels up to a maximum length of 15
characters including the interface name and colon (e.g. eth0:foobar1234)

Hence the total number of characters must not exceed 15 characters.


The total number of characters for devicename, colon and iflabel (e.g. vlanXXXX:somelabel) was exceeded.
