Summary should say it all - I'm running a VG with two crytped PVs, and /etc/init.d/dmcrypt is able to decrypt them, but unfortunately it's too late to get recognised by /etc/init.d/lvm which already ran before, so I need to run "vgchange -a y" manually after the dmcrypt-init-script.
I don't know much about gentoo init scripts and how this problem is best resolved, so my quick workaround was to add "lvm" to the depend-section in /etc/init.d/dmcrypt .
Steps to Reproduce:
1. configure /etc/conf.d/dmcrypt to decrypt LVM Physical Volumes
Crypted LVs are not usable at system startup
/etc/init.d/lvm runs after /etc/init.d/dmcrypt
This is going to always have to be a manual one because many people use encrypted LVs instead of encrypted PVs so they need dmcrypt to start after LVM.
Inside of /etc/conf.d/lvm put:
And that should make it depend on dmcrypt being started.
