Hi @Ksahil !

Can you check with :  #rpm -qa | grep -i vdo 

                                   #which vdo 

                                   #systemctl daemon-reload 

                                   #systemctl start vdo

I have not ever used or tried VDO before. 

Is there an actual service that needs to run? The documentation for RHEL 8 and 9 suggests that there is not -> https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/deduplicating_and_comp...

VDO was a service in RHEL 8 (we taught it that way). Here's my slide for this (again RHEL 8 not 9):

It doesn't appear to be a service in RHEL 9; there is no vdo.service unit file. Instead, it has become an option that is used with LVM. For example:

Yeah, that's what I was expecting too, based on the documentation.

Yes you are right, starting RHEL 9 VDO is now part of LVM. You can refer to this documentation explaining use of VDO on RHEL 9
