[linux-lvm] want to remove a disk



I installed a new fedora box with 2 hard disks. The system disk and a second one to be used to backup and get information out of the machine.
The problem was that inadvertely the disks mounted in a lvm configuration as follows:
 
 
[root s2]# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                     150202484  56184212  86265364  40% /
/dev/sda1               101086     10442     85425  11% /boot
tmpfs                   250336         0    250336   0% /dev/shm
==============================================================
So now I cannot remove the 2nd disk without disrupting the system.
Can I use
lvremove or lvchange
doing lvdisplay shows:
==============================================================
 
[root s2]# /usr/sbin/lvdisplay
  --- Logical volume ---
  LV Name                /dev/VolGroup00/LogVol00
  VG Name                VolGroup00
  LV UUID                AG2uKb-0VMO-5qn4-T2LK-cjM8-mZbh-jETkyx
  LV Write Access        read/write

  Current LE             4732
  Segments               2

  Block device           253:0
 
  --- Logical volume ---
  LV Name                /dev/VolGroup00/LogVol01
  VG Name                VolGroup00
  LV UUID                8Q6XKF-bz8D-vcan-Izf9-Ntzn-XmYv-9WAi5g

==============================================================
which command should I use to leave all information on the /dev/sda1 and be able to take out the other disk?
 
Thank you!
