Bug#247780: partman LV filesystem detection problem
Rather than repartition, this time I chose to leave my partitioning as it
(/dev/hda2 = ext3
/dev/hda3 = swap
/dev/hda4 = LVM)
and reactivate the existing VG. This worked fine, and the partitioner showed
the partition arrangement as it should.
When I then went to each LV, and went to mount them, the partitioner said
that no filesystem was detected on the LV, and only gave me the choice of
formatting it, not leaving it as it was and mounting it.
I suspect something's amiss with the filesystem detection code.
