Environment

vSphere vCenter Server 7.0.x

Cause

Some authz logs are being redirected to stderr causing storage issues on VCSA

Resolution

Workaround:

1. Make a backup copy of the wcpsvc-vmonconfig.json config file

cp /etc/vmware/vmware-vmon/svcCfgfiles/wcpsvc-vmonconfig.json /tmp/wcpsvc-vmonconfig.json.bak

Note: Files in /tmp are removed once vCenter is rebooted. Therefore, you might want to save this in your computer.

2. Edit the wcpsvc-vmonconfig.json file 
 
vim /etc/vmware/vmware-vmon/svcCfgfiles/wcpsvc-vmonconfig.json

3. Remove the line beginning with StreamRedirectFile and save the file.
 
{
    "Name" : "wcp",
    "StartCommand" : "/usr/lib/vmware-wcp/wcpsvc.launcher",
    "StartCommandArgs": ["--port", "8920", "--logfile", "/var/log/vmware/wcp/wcpsvc.log",
                         "--configfile", "/etc/vmware/wcp/wcpsvc.yaml",
                         "--audit-logfile", "/var/log/vmware/wcp/wcp-audit.log",
                         "--incident-logfile", "/var/log/vmware/wcp/wcp-incident.log"],
    "PreStartCommand" : "%VMWARE_PYTHON_BIN%",
    "PreStartCommandArgs" : ["/usr/lib/vmware-wcp/wcpsvc-prestart.py"],
    "StreamRedirectFile" : "/var/log/vmware/wcp/stdstream.log",                                -----------------------> # line to be modified
    "RecoveryActionProfiles" :
    {
        "DEFAULT" :
        {
            "CRASH" : ["RESTART_SERVICE", "RESTART_SERVICE", "RESTART_SERVICE", "RESTART_SERVICE", "RESTART_SERVICE", "NO_ACTION"],
            "HEALTHFAIL" : ["NO_ACTION"]
        }
    },
    "WorkingDir" : "/usr/lib/vmware-wcp/",
    "DependsOn" : ["vpxd", "eam", "vmware-vpostgres", "lookupsvc", "cis-license", "vapi-endpoint", "sts", "trustmanagement"],
    "ApiHealthCommand" : "%VMWARE_PYTHON_BIN%",
    "ApiHealthCommandArgs" : ["/usr/lib/vmware-vmon/vmonApiHealthCmd.py", "-n", "wcp", "-u", "/wcp/health", "-t", "10"],
    "StartTimeout" : 120,
    "StopTimeout" : 30
}
 

4. Restart wcp service
 
service-control --stop wcp && service-control --start wcp
