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
LV Status available
# open 1
LV Size 147.88 GB
Current LE 4732
Segments 2
Allocation inherit
Read ahead sectors 0
Block device 253:0
--- Logical volume ---
LV Name /dev/VolGroup00/LogVol01
VG Name VolGroup00
LV UUID 8Q6XKF-bz8D-vcan-Izf9-Ntzn-XmYv-9WAi5g
LV Write Access read/write
LV Status available
# open 1
LV Size 992.00 MB
Current LE 31
Segments 1
Allocation inherit
Read ahead sectors 0
Block device 253:1
==============================================================
which command should I use to leave all information on the /dev/sda1 and be able to take out the other disk?
Thank you!
Alejandro

You should give more informations, like where does VG VolGroup00 stands
(sda1 ?). Try the following :
vgdisplay
pvdisplay

Thank you for your answer Fabien. The result of vgdisplay and pvdisplay

As far as I understand there are two 80GB HD sata. One as a master (sda2)
and one as slave (sdb2).
I would like to have all the logical volume data on the sda2, and be able to
remove the sdb2 without disrupting the server.
Is that possible?
Thanks,
Alejandro
