First you'll need this recent fix: https://sourceware.org/git/?p=lvm2.git;a=commitdiff;h=f611b68f3c02b9af2521d7ea61061af3709fe87c --force was broken at some point, and the option is now --lockopt force. To change between lock types, you are supposed to be able to change to a local VG, then from local to the other lock type. The man page sections: changing a lockd VG to a local VG changing a local VG to a lockd VG But it looks like a fix is needed in those instructions. I believe "vgchange --lock-type none <vgname>" needs to include --lockopt force. If you could verify this for me, I'll update the man page.
