hi
I have installed a new drive in my computer and it has only linux fedora core 4 installed on it.I am desperatly trying to mount the partition but it's not working

I used the /sbin/fdisk -l comand so i would know what the partition name. i got this :

Disk /dev/hda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot
/dev/hda1 *
/dev/hda2
..................
/dev/hda11
/dev/hda12

Disk /dev/hdd: 30.0 GB, 30020272128 bytes
255 heads, 63 sectors/track, 3649 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hdd1 * 1 13 104391 83 Linux
/dev/hdd2 14 3649 29206170 8e Linux LVM

and tryed to mount using: mount /dev/hdd2 /mnt/sec_drv -t auto
It didn't work because i had to specify a filesystem type.
My question is:
What is the filesystem for that partition?? Or what am i doing wrong
Thenx

It seems that you have created a Logical Volume on you HD. (LVM : Logical Volum Manager)

Unless you really want a LVM partition on this HD, change the tpye of /dev/hdd2 to 83 (Linux). After that, create a filesystem on it and you ready to go.
The commands:
# fdisk /dev/hdd (t, 2, 83, w are the keys to change the type of partition 2 to 83 and write the modifications).

#mkfs -t ext3 /dev/hdd2

#mount /dev/hdd2 /mnt/sec_drv

regards,

What OS is on the machine other than on the new disk?
From what OS are you issuing fdisk command?

i have an fedora core 4 on bolth hdd's, I belive it would help if you understood that when i instaled linux i let it make the partitions. So now i have a lot of info that i must extract from my second hdd. I can't boot form my second hdd(the one i am trying to mount) because linux was installed on a nother sistem.

What partitions are mounted right now in your machine ?
(just give me the output of command "mount")

ok here is the output of mount:
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
/dev/proc on /proc type proc (rw)
/dev/sys on /sys type sysfs (rw)
/dev/devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/hda11 on /boot type ext3 (rw)
/dev/shm on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
automount(pid2017) on /misc type autofs (rw,fd=4,pgrp=2017,minproto=2,maxproto=4)
automount(pid2064) on /net type autofs (rw,fd=4,pgrp=2064,minproto=2,maxproto=4)
Sorry for the delay...
Hope you cna help me i really need the files on that partition.

what are the output of (as root)
# pvdisplay /dev/hdd2
and
# lvdisplay -v /dev/mapper/VolGroup00-LogVol00

The output of lvdisplay is quite long and boring. Just give me the initial section until the output:

--- Logical extents ---
LE PV PE reads writes
blah blah blah....

ok the output for pvdisplay /dev/hdd2 is:
Physical volume ---
PV Name /dev/hdd2
VG Name VolGroup00
PV Size 27.84 GB / not usable 0
Allocatable yes
PE Size (KByte) 32768
Total PE 891
Free PE 1
Allocated PE 890
PV UUID NklpPc-OLOf-5SEs-2YJg-YQQ1-JcST-ujxDsw

and lvdisplay -v /dev/mapper/VolGroup00-LogVol00 :

Using logical volume(s) on command line
Wiping cache of LVM-capable devices
Volume group "mapper" not found

it's all of it.
Thenx for your help
