Public bug reported:
After upgrading one of my machines from 14.04 to 16.04 and switching
back to upstart the system stopped booting. It turned out that after
initramfs inovokes /sbin/init system hangs on mountall job waiting
indefinitely for LVM devices to appear.
Problem affects all 16.04 installations (both 14.04 upgrades or fresh
ones) where LVM devices are included in /etc/fstab. Below are example
log entries that are filling /var/log/upstart/mountall.log when
"init=/sbin/upstart --debug" is added to kernel command line:
try_mount: /var/lib/postgresql waiting for device
try_mount: /var/spool/bacula waiting for device
try_mount: UUID=886c73fd-8392-4361-956e-9cda47b0eb65 waiting for device
My system is:
Description: Ubuntu 16.04.2 LTS
Release: 16.04
All devices in fstab are referenced by UUIDs.
To workaround the problem simple script executing "lvm vgchange -ay"
must be created and placed in /etc/initramfs-tools/scripts/local-top
Problem doesn't exist when using systemd.
