I am using Ubuntu Gutsy, which is the in-development branch heading for
their next stable release.
I have noticed that since some kernel release post-2.6.20 I have been
unable to mount my /boot partition:

All other block devices (all LVM LVs) seem to mount with no problems.
Certainly I leave open the possibility of pilot error (by either me or
Ubuntu) but I don't know how to even see why/where/what could be going
wrong.
/proc/mounts does not show the device mounted:
$ grep hda /proc/mounts
$
and fuser and lsof doesn't show anything using the mount point:
$ fuser /mnt/foo
$ sudo lsof | grep /mnt/foo
$
Nor does lsof show /dev/hda (device 3,1) in use:
$ sudo lsof | grep -e hda -e 3,1
$
So I'm kind of perplexed as to what to try next in how to debug
this?
Any ideas? Thanx in advance.

Indeed. Very unfortunate. I did re-post with a subject but I have not
seen it show up yet, which I have been waiting for to post the solution.
Maybe I will just do that here and again if it shows up with the subject
posted.
The crux of the problem is that the real partitions are being
mapped/managed by device mapper, which is being used by LVM:
$ ls -l /dev/mapper/
total 0
crw-rw---- 1 root root 10, 63 2007-08-08 04:56 control
lrwxrwxrwx 1 root root 7 2007-08-08 04:56 hda1 -> ../dm-0
lrwxrwxrwx 1 root root 7 2007-08-08 04:56 hda2 -> ../dm-1
lrwxrwxrwx 1 root root 7 2007-08-08 04:56 hda3 -> ../dm-2
This is of course causing those partitions to be opened exclusively,
preventing any further uses (i.e. sys_mount()) from being able to use
them. Only hda3 of those above is actually an LVM PV. hda1 is an ext3
filesystem (/boot) and hda2 is a FAT32 (could even be FAT16) filesystem.
Of course, mounting /dev/dm-0 instead of /dev/hda1 solves the problem.
Why this started with Ubuntu's 2.6.22 kernel in Gutsy, I'm not sure.
Whether it's a new DM feature or some change in the way Ubuntu handles
devices, I don't know. Whatever the case, they need to fix
their /dev/disk/by-uuid mappings anyway:
$ ls -l /dev/disk/by-uuid/ | grep hda
lrwxrwxrwx 1 root root 10 2007-08-08 08:56 12b8250a-d031-4ee1-b486-5e67478d06b4 -> ../../hda1
Cheers,
b.

Probably something to do with either LVM or the Device Mapper having
the raw partition already "open" for some remapping purpose.
There was a note about that around here somewhere quite recently..

Indeed, that was it. I posted a followup "Re: [SOLVED] problems while
mounting /boot partition" reporting such.
Thanx for the heads up though!

Actually, given the volume on LKML, a line without a subject is making
the most attention since all others do have one. :)
