How to mount a LVM?

Hey all,

I got it to work ONCE, but for the life of me I can't figure out how to do
it again.

This is what I think I did the first time, but for the second time it just
doesn't work.

root@dotcom:~# mdadm --assemble --scan
mdadm: /dev/md/2 has been started with 1 drive.
mdadm: /dev/md/3 has been started with 1 drive.

---OK, good so far. Now let's find the LVs

root@dotcom:~# lvmdiskscan
  /dev/loop0 [     213.51 MiB]
  /dev/loop1 [     206.55 MiB]
  /dev/sda1  [      30.00 GiB]
  /dev/loop2 [     220.89 MiB]
  /dev/md2   [     926.91 GiB] LVM physical volume
  /dev/loop3 [     208.05 MiB]
  /dev/md3   [     926.91 GiB] LVM physical volume
  /dev/sda5  [       2.00 GiB]
  /dev/sda6  [      30.00 GiB]
  /dev/sda7  [     200.00 GiB]
  /dev/sda8  [     203.76 GiB]
  /dev/sdb1  [       2.37 GiB]
  /dev/sdb2  [       2.00 GiB]
  /dev/sdc1  [       2.37 GiB]
  /dev/sdc2  [       2.00 GiB]
  /dev/sdd1  [     465.76 GiB]
  /dev/sde1  [     149.05 GiB]
  0 disks
  15 partitions
  0 LVM physical volume whole disks
  2 LVM physical volumes

---Still looking good. Now I'm supposed to find the logical volumes,
---but lvdisplay simply doesn't show anything.

root@dotcom:~# lvdisplay
root@dotcom:~#

---Now I'm stuck. All LVM instructions I find on the Internet say that I
find the path of the LVM device by using lvdisplay. Also I know that one
hour ago I had my volumes mounted and was copying data from them. After
properly syncing and unmounting them, and stopping the LVM and md thingys,
I'm stuck now.

Any suggestions?
