Description
How to manually increase the swap space of a GMS Virtual Appliance (VA) to the recommended 2GB value?
Resolution
This procedure is for SonicWall Technical Support only! Do not publish to external.
To manually increase the swap space of a GMS Virtual Appliance:
- Add the following script snippet to the end of the start() function in /opt/GMSVP/bin/S999sgms
# Add swap space
if [ ! -e /opt/GMSVP/data/swapfile ]; then
dd if=/dev/zero of=/opt/GMSVP/data/swapfile bs=1024 count=2097152
/sbin/mkswap /opt/GMSVP/data/swapfile
fi
/sbin/swapon -e /opt/GMSVP/data/swapfile
- In the above case, we created a swap file and allocated additional 2GB to the swap. (bs=1024: block size - 1KB; count=2097152: 1024x1024x2 – MB->GB->2GB)
- Check the swap space.
- top (example below)
top - 14:03:58 up 24 min, 0 users, load average: 0.00, 0.02, 0.09
Tasks: 93 total, 1 running, 92 sleeping, 0 stopped, 0 zombie
Cpu(s): 1.8%us, 0.0%sy, 0.0%ni, 98.2%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st
Mem: 8186032k total, 3255448k used, 4930584k free, 53924k buffers
Swap: 4057032k total, 0k used, 4057032k free, 713060k cached
- cat /proc/swaps (example below)
[root@aman-esxi-testunit bin]# cat /proc/swaps
Filename Type Size Used Priority
/dev/sda5 partition 1959888 0 -1
/opt/GMSVP/data/swapfile file 2097144 0 -2
- It takes a while to create the swapfile (the first time) and swapon the space. So please check the status few minutes after the boot.
