I just ran into this with a cleanly installed 17.04. Figured it out myself, added "copy_exec /usr/sbin/cache_check" to /usr/share/initramfs- tools/hooks/lvm2 in order to fix it.
Can we PLEASE get this bug -- which renders systems UNBOOTABLE after attaching a cache -- fixed, especially since there are good and reasonable patches available already (#12)? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1423796 Title: Unable to mount lvmcache root device at boot time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1423796/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
