[RndTbl] LVM import question

[Kevin McGregor]

We're aiming for an off-line scan; I'll look into sysresccd as an option.

As for mounting the LVs, I get this sort of result:
root at cowsvplav01:~# pvs
  PV         VG        Fmt  Attr PSize  PFree
  /dev/sdb5  ubuntu-vg lvm2 a--  14.76g 268.00m
root at cowsvplav01:~# vgs
  VG        #PV #LV #SN Attr   VSize  VFree
  ubuntu-vg   1   2   0 wz--n- 14.76g 268.00m
root at cowsvplav01:~# lvs
  LV     VG        Attr      LSize    Pool Origin Data%  Move Log Copy%
 Convert
  root   ubuntu-vg -wi------   13.50g
  swap_1 ubuntu-vg -wi------ 1020.00m
root at cowsvplav01:~# ls /dev/mapper
control
root at cowsvplav01:~#

So I don't know how I'm going to mount any of it. Yes, I've hot-added it.
FWIW, I'm using VMware ESXi 5.1.
