I was experiencing the same issue as describe in this bug report and, as
pointed by Harrison Metzger, the bug was probably introduced after
kernel 3.16-3-amd64 because for sure it was working until that version.
I don't get what causes the problem. It could be interesting to test if
the problem is affect only if the mirror is a type raid1 or also if it
is a type "mirror" (legacy). I don't know neighter if there is a problem
while shutting down (is it the same if the OS reboot or it before
rebooting the mirror is deactivate?).
But the funniest thing is that if you activate lvmetad (switch to option
"use_lvmetad = 1" in /etc/lvm/lvm.conf) the lvm with mirror type as
raid1 starts to work again after reboot (at least tested on squeeze
Linux 4.9.0-0.bpo.2-amd64 #1 SMP Debian 4.9.13-1~bpo8+1 (2017-02-27)
x86_64 GNU/Linux). I don't know why nor it seem documented. Hope that
this will save some headache to you as well.
Cheers,
