Comment 123 for bug 332270

I had similar trouble, removing 'watch' didn't change a thing for me (can't seem to get any of these updates while in jaunty_beta?). I realize therefore my problem is not related to this bug, still I realize that more people will find this bug when searching for heir answer later; let me explain how I solved my issue for reference:

FWIW I found out that 'lvchange -a y' was taking ages on my volume group that contained a snaphot of 18Gb that was 50% full. Ages measuring in minutes, it would prevent successfull boot. I found out by doing repeated

/sbin/lvm vgchange -a n
/sbin/lvm vgchange -a y # takes ages

/sbin/lvm lvremove vg/largish_snapshot

/sbin/lvm vgchange -a n
/sbin/lvm vgchange -a y # takes seconds

Of course I made a backup of the data in the snapshot that I actually wanted to keep :)

Anyone seeing prolonged disk activity while failing boot, check this. I'm considering to file this as a bug against lvm2 (unless I find some documentation on lvm2 that I should have read, stating that this behaviour is by design).
