[Bug 1396213] Re: LVM VG is not activated during system boot
I've generated the report and I'm trying to use what the linked tutorial
suggests:
$ ubuntu-bug -c 1396213.apport -u 1396213
Usage: ubuntu-bug [options] [symptom|pid|package|program path|.apport/.crash file]
ubuntu-bug: error: -u/--update-bug option cannot be used together with
options for a new report
That tutorial must be outdate, and I couldn't figure out how the syntax
changed to make it send the report and file it under this existing bug.
I get the same with "apport-cli". What is the correct command to use if
I have the report file, and want it to be attached here?

Title:
LVM VG is not activated during system boot
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
Hi all,
I open this report based on the linked conversation I had on the linux-lvm mailing list, and the Ask Ubuntu question I posted regarding this case.

http://askubuntu.com/questions/542656/lvm-vg-is-not-activated-during-system-boot
I have 2 VGs on my system, and for some reason, only one of them gets
activated during the initrd boot sequence, which doesn't have my root
LV, so my boot sequence halts with an initrd prompt.
When I get to the initrd BusyBox prompt, I can see my LVs are inactive
with "lvm lvscan" – then, "lvm vgchange -ay" brings them online. The
boot sequence continues as I exit the BusyBox prompt. The expected
behaviour would be that both VGs should activate automatically.
On LVM mailing list, I've been advised it may be a problem with Ubuntu
initrd scripts, hence I report this problem here. (I'm not sure if I'm
reporting it to the correct place by assigning it to "linux", but I
didn't find a package directly related to the initrd only, so I
assumed initrd scripts are maintained by the kernel team. If you think
it's an error, and know the correct package, please reassign!) Our
suspicion is, initrd prematurely issues "vgchange -ay" before all the
PVs come online. This makes sense.
I already tried to set the "rootdelay" kernel parameter to make initrd
wait longer for the boot LV to come up, but it didn't work. Note
however, it worked with previous kernel versions.
The problem came up when I upgraded to Utopic, and got kernel
vmlinuz-3.16.0-23-generic. When I boot with the old kernel from Trusty
(vmlinuz-3.13.0-37-generic), it works fine.
