Public bug reported:
After installing xenial using the daily ubuntu-server installer,
creating an LVM volume for the root filesystem, I lvconverted it into a
raid1 mirror for redundancy over the pair of SSDs installed (as separate
LVM PVs):
sudo lvconvert -m 1 --type raid1 bonk/bonk1 /dev/sdc1 /dev/sdd1
After a reboot, the lvm2-monitor.service fails. Relevant lines from
journalctl:
$ sudo journalctl | grep -iE '(lvm|dmeventd)'
