I have upgraded my server from 11.04 to 11.10 (64 bit) using sudo do-release-upgrade

The machine now halts during boot because it can't find certain logical volumes in /mnt. When this happens, I hit "m" to drop down to a root shell, and I see the following (forgive me for inaccuracies, I'm recreating this):

$ lvs

  LV       VG   Attr   LSize   Origin Snap%  Move Log Copy%  Convert

  audio    vg   -wi--- 372.53g                                      

  home     vg   -wi-ao 186.26g                                      

  swap     vg   -wi-ao   3.72g                                      

The corresponding block devices in /dev are missing for "audio".

If I run:

$ vgchange -a y

$ lvs

  LV       VG   Attr   LSize   Origin Snap%  Move Log Copy%  Convert

  audio    vg   -wi-ao 372.53g                                      

  home     vg   -wi-ao 186.26g                                      

  swap     vg   -wi-ao   3.72g                                      

Then all LVs are activated and the system continues to boot perfectly after exiting from the root maintenance shell.

What is going on, and how would I set the LVs to always be active on boot up?

Update to answer questions raised:

There is one volume group:

# vgs

  VG   #PV #LV #SN Attr   VSize VFree

  vg     1   6   0 wz--n- 1.68t    0 

# pvs

  PV         VG   Fmt  Attr PSize PFree

  /dev/md2   vg   lvm2 a-   1.68t    0 

Over a RAID1 MD array consisting of a matched pair of SATA hard disks:

 # cat /proc/mdstat 

 Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] 

 md2 : active raid1 sda3[0] sdb3[1]

       1806932928 blocks [2/2] [UU]



 md1 : active raid1 sda2[0] sdb2[1]

       146484160 blocks [2/2] [UU]



 md3 : active raid1 sda4[0] sdb4[1]

       95168 blocks [2/2] [UU]



 unused devices: <none>

So:

 # mount

 /dev/md1 on / type ext4 (rw,errors=remount-ro)

 proc on /proc type proc (rw,noexec,nosuid,nodev)

 sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)

 none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880)

 none on /run/shm type tmpfs (rw,nosuid,nodev)

 /dev/md3 on /boot type ext3 (rw)

 /dev/mapper/vg-home on /home type reiserfs (rw)

 /dev/mapper/vg-audio on /mnt/audio type reiserfs (rw)

 rpc_pipefs on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)

 nfsd on /proc/fs/nfsd type nfsd (rw)

Update with full lvdisplay - as suspected the partitions that work are first in the list. Can't see anything odd myself. I've included the full list here - this is all my LVM partitions.

This is from the running machine, if output from the broken state is useful that'll need some time to obtain.

Update 2012/01/28: a reboot has given an opportunity to look at the machine in its broken state.

I don't know if relevant, but the machine was shut down cleanly but the file systems were not clean on starting up again.
