6027-2794 [E] Invalid content of disk paxos sector for disk diskName.
Explanation
In an environment where tie-breaker disks are used,
the contents of either one of the tie-breaker disks or the ballot
files became invalid, possibly because the file has been overwritten
by another application.
User response
Examine mmfs.log file on
all quorum nodes for indication of a corrupted ballot file. If 6027-2793
is found then follow instructions for that message. If problem cannot
be resolved, shut down GPFS across
the cluster, undefine, and then redefine the tiebreakerdisks configuration
variable, and finally restart the cluster.
