I believe this is normal behavior for LVM. LVM has to build an overlay layer from all of the blocks contained in the snapshot so they are available via access to the "parent" LV at any time.
The larger the snapshot, the longer it takes to read in all of the blocks and build the overlay layer. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/360237 Title: cannot boot root on lvm2 with (largish) snapshot To manage notifications about this bug go to: https://bugs.launchpad.net/lvm2/+bug/360237/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
