Can't get sudo vgchange -a y to work anymore

[mrblotto]

Hey hey everyone!

Part of my job is to 'refresh' or 'migrate' peeps laptops to a supported version. We've begun using RHEL 7.5 for a couple months.

I've been getting requests to migrate folks from RHEL 6.9 to 7.5. As far as I know, there is no easy upgrade path. More likely, a total rebuild is required

Anyhow, I used to be able to
-Slave out HD to my own RHEL lappy
-Enter the LUKS pwd when prompted
-Go to a terminal and type in 'sudo vgchange' followed by 'sudo vgchange -a y' in order to backup peeps data prior to rebuilding
But that no longer seems to work

Is it simply a problem between RHEL 6 and 7? I had talked with someone and they suggested using the 'chown' command, but I'm not entirely sure how to do that

Thx for listening!
Blah-Toe

Update: OK I think I got it

I used the info from this url:

https://access.redhat.com/documenta...ep_by_Step_Guide/s1-navigating-ownership.html

In a nutshell I used chmod 666 -R on the slaved out drive to give me all permissions. The HD is going to be wiped out anyhow. I'm backing up the stuff now. It's much faster than waiting days for the cloud restore to happen
