Well
I make some POC but doesn't seems to me any advantage in use VDO.
Without VDO I have created a single Ubuntu VM Server, and the SO just
used 3.6G.
But using VDO I noticed that the underlay used the very same 3.6G.
Perhaps I am doing something wrong.
I had have used the following command in order to create VDO:
vdo create --name=vdo1 --device=/dev/sdb --emulate512=enabled
--vdoLogicalSize=200G
Thanks for any advice.
Well, I use VDO on RHEL based backup server and here is how it looks like:
vdostats --si
Device Size Used Available Use% Space saving%
/dev/mapper/vdo1 3.8T 2.3T 1.6T 59% 54%
df -h
/dev/mapper/vdo1 7,5T 4,6T 3,0T 61% /BACKUP
As you can see I saved 1/2 of space.
On filesystem level file sizes will be the same , of course...

Are you sure you did enable the '--emulate512' when creating VDO ?
I'm sure we did not add this option.
Thank you, we'll try .
