Description

When we have a single voting file CSSD report the file offline, but thre is no IO error or hung condition
previous to taking the voting file offline:

[    CSSD][29](:CSSNM00018:)clssnmvDiskCheck: Aborting, 0 of 1 configured voting disks available, need 1
[    CSSD][29]###################################
[    CSSD][29]clssscExit: CSSD aborting from thread clssnmvDiskPingMonitorThread
[    CSSD][29]###################################
[    CSSD][29](:CSSSC00012:)clssscExit: A fatal error occurred and the CSS daemon is terminating abnormally

Rediscovery Notes:

If there is no IO error or IO hung that caused to set the voting file offline, then we may be getting this bug.

Workaround
Use more than 1 voting file.
