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 Do not publish to external.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:

1.  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

2.  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)

3.  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

4. 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.
