Symptoms

NOTE: The NetWorker VMware Backup Appliance (VBA) is no longer supported. VMware protection is now performed using the NetWorker VMware Protection (NVP) vProxy appliance.

The VBA /var file system is full. 
admin@VBA-Name:~/>: df -kh
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda2             7.9G  5.7G  1.8G  77% /
udev                  3.9G  136K  3.9G   1% /dev
tmpfs                 3.9G     0  3.9G   0% /dev/shm
/dev/sda1             130M   38M   86M  31% /boot
/dev/sda7             1.5G  1.4G     0 100% /var
/dev/sda9              70G   13G   54G  20% /space
/dev/sdb1             256G   20G  237G   8% /data01
/dev/sdd1             256G   13G  244G   5% /data02
/dev/sdc1             256G   12G  245G   5% /data03
When analyzing the /var file system consumption, it is then determined that the majority of the disk space is consumed by the logs located in the "/var/log/apache2."

Cause

Tomcat listens to port 9443 and also, whenever tomcat service does not run and simultaneously when anyone tries to access tomcat services, the errors regarding tomcat not running gets flooded in /var/log/apache2/mod_jk.log.

Note: The default web services configuration does not limit the number of logs retained or the size of each log. In environments with large activity the default tomcat web services configuration may lead to the var file system becoming full.

 

Resolution

Perform the following on the vProxy appliance.

1. Open an SSH session to the VBA, log in as admin, then switch to root:

2. Change the directories to the apache2 directory:

cd /var/log/apache2/

3. Confirm disk space usage with the following du command:

root@ VBA-Name:/var/log/apache2/#: du -sh
1.3G

4. Run the following ls command to review the file size and disk usage:

root@ VBA-Name:/var/log/apache2/#: ls -lhtr
    total 1.3G

NOTE: The mod_jk.log file accounts for most of the apache2 disk usage.

5. Stop services:

root@ VBA-Name:/var/log/apache2/#: website stop
===Shutting down website
Shutting down httpd2 (waiting for all children to terminate)                      done
            6.   Remove the mod_jk.log file from the appliance. Once the website services are started a new mod_jk.log would be generated. 
root@ VBA-Name:/var/log/apache2/#: rm mod_jk.log

7. Start the website service:

root@ VBA-Name:/var/log/apache2/#: website start 
===Starting website 
Starting httpd2 (prefork)                                                      done

8. Confirm that that disk space usage has reduced:

root@ VBA-Name:/var/log/apache2/#: df -kh
    Filesystem            Size  Used Avail Use% Mounted on
    /dev/sda2             7.9G  5.7G  1.8G  77% /
    udev                  3.9G  136K  3.9G   1% /dev
    tmpfs                 3.9G     0  3.9G   0% /dev/shm
    /dev/sda1             130M   38M   86M  31% /boot
    /dev/sda7             1.5G  172M  1.2G  13% /var
    /dev/sda9              70G   13G   54G  20% /space
    /dev/sdb1             256G   21G  235G   9% /data01
    /dev/sdd1             256G   13G  244G   5% /data02
    /dev/sdc1             256G   12G  245G   5% /data03

9. Verify if the new mod_jk.log has been generated.

root@ VBA-Name:/var/log/apache2/#: ls -lhtr | grep -i mod_jk.log
    -rw------- 1 root root  600 Nov  8 14:32 mod_jk.log
