Comment 133 for bug 290153

Ok, my symptoms resolved: 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

/sbin/lvm lvremove vg/snapshot

/sbin/lvm vgchange -a n
/sbin/lvm vgchange -a y

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, or head over to bug #332270... I'm still 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).

Regards,
Seth
