/storage/log partition full due to cloudvm-ram-size.log file rotation is not working in vCenter Server Appliance

Products

• VMware vCenter Server

Issue/Introduction

Symptoms:

• In VCSA 6.0, the /storage/log/vmware/cloudvm/cloudvm-ram-size.log file size increases without log rotation.
• The available space in the /storage/log directory reduces gradually.

Environment

VMware vCenter Server Appliance 6.0.x

Cause

This issue occurs due to the absence of log rotation configuration for the cloudvm-ram-size.log file.

Resolution

This issue is fixed in vSphere 6.5.

For previous vSphere versions, work around this issue by manually configuring log rotation for the cloudvm-ram-size.log file.

To manually configure log rotation for the cloudvm-ram-size.log file:
 

1. Log into the vCenter Server Appliance.
2. Navigate to:
   
   /etc/logrotate.d
    
3. To create the cloudvm_ram_size.log file, run this command:
   
   touch /etc/logrotate.d/cloudvm_ram_size.log
    
4. Open the cloudvm_ram_size.log file created in step #3 using a text editor.
5. Enter these entries:
   
   /storage/log/vmware/cloudvm/cloudvm-ram-size.log{
   missingok
   notifempty
   compress
   size 20k
   monthly
   rotate 5      
   create 0660 root cis
   }
    
6. Save the cloudvm_ram_size.log file.
    
7. To enable log rotation for the cloudvm-ram-size.log file and all the other log files, run this command:
   
   logrotate -f /etc/logrotate.conf
   
   Notes:
    
   • You may see some errors while running the logrotate command, which can be ignored.
   • You can keep the latest cloudvm-ram-size.log-xxxxxxxxx-.bz2 file.
   • It is recommended to do periodic cleanup of older .bz2 files in the /storage/log/vmware/cloudvm location.
