vmdk of pfsense esxi is much larger then the actual space used
-
Hi,
I had installed pfsense for openvpn in esxi. i recently took its backup in vmware and its size was around 60GB. but when i looked pfsense using df -h it was not using this much space as shown below. i checked on various sites. they recomend to zero out the unused space in the guest vm and then use vmwar tools to shrink vmdk file.What tool should i use in pfsense to zero out unused space so that i can reduce the vmdk size.

https://supratim-sanyal.blogspot.com/2016/12/zero-out-free-disk-space-on-virtual.htmldoes this code to zero out disk looks good ?
pfSense (freeBSD)On my pfSense open-source router virtual machine, I run this script:
#!/bin/sh -x # # --- # zerofree.sh (pfSense) # # Zeroes Out Ununsed Disk Space for subsequent compacting of virtual hard disk # Tested on pfSense 2.3 / FreeBSD 10.3 # To execute: nice -19 ./zerofree.sh # # Supratim Sanyal - supratim at riseup dot net # See http://supratim-sanyal.blogspot.com/2016/12/zero-out-free-disk-space-on-virtual.html # --- # cd / cat /dev/zero > zero.delete-me rm -v zero.delete-me -
Do you have SWAP enabled? What size is it if so?
