vSphere Client is displaying a warning "Log Disk Exhaustion on <vcenter-name>" on the summary page for the vCenter Server Upon investigation the folder /var/log/vmware/wcp is found to be one of the or the largest folder on the /storage/log partition looking in the folder, there is one or more very large stdstream.log files, similar to the example below: # ls -althrS /var/log/vmware/wcp | tail -5 1.4M -rw------- 1 wcp lwisRegReader 1.4M <DATE> <TIME> stdstream.log-1.stderr 34M -rw------- 1 wcp lwisRegReader 34M <DATE> <TIME>stdstream.log-4.stderr 111M -rw------- 1 wcp lwisRegReader 111M <DATE> <TIME> stdstream.log.stderr 1.1G -rw------- 1 wcp lwisRegReader 1.1G <DATE> <TIME> stdstream.log-3.stderr 1.6G -rw------- 1 wcp lwisRegReader 1.6G <DATE> <TIME> stdstream.log-0.stderr
to prevent disk space exhaustion in the /storage/log partition
The stdstream.log.stderr logs are currently not rotated by size, but only when the wcp service restarts. When wcp runs for longer amounts of this, their size can therefore grow quite large, thus allocating large portions of the space available in /storage/log, and potentially resulting in the space getting exhausted.
Currently there is no permanent solution available.VMware engineering is aware of this issue and working towards a fix in a future release
To mitigate this problem, please take a fresh backup of the vCenter Server Appliance, then remove all stdstream.log* files from the folder and restart the wcp service: # service-control --stop wcp; rm /var/log/vmware/wcp/stdstream.log*; service-control --start wcp
