I use LVM with full disk encryption. I also use LVM snapshots, currently I have a 70GB snapshot.

Now the only problem is that the boot times when LVM snapshots are present are extremely long.

I boot my machine, enter my encryption passphrase and then wait for about 3 minutes. It is only after that long wait does my machine boot.

This only happens if snapshots are present, if no snapshots are present, boot is almost instantaneous after I enter my passphrase.

Will adding --skip-mappings help ?

Is there any way this can be solved ?
