Mount hard drive to new CentOS 6 install

Question

I installed Linux CentOS 6 on a new hard drive. GNOME automatically mounted my old drive to /media/bf90bc42-1b10-4c6f-9b58-f0e52d103907. Long number maybe is a some type of UUID. I even umounted it with same results.

I want to mount vg_wiwan50-lv_root to /mnt/WD2TB and my other hard drives (data stuff, not system boot stuff).

These LVM confuse me so much (computer nerd for 20 years with servers).

I tried these commands:

[root@server /]# lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0   1.8T  0 disk

Answer 1

Some basic information about LVM can be found here, you are trying to mount /dev/sda2 which is a physical volume and can't be mounted, you need to mount the logical volume(s):

mount /dev/mapper/vg_wiwan50-lv_root /mnt/<mountpoint>

for root filesystem and

mount /dev/mapper/vg_wiwan50-lv_home /mnt/<mountpoint>

for home filesystem.

The automount to /media/bf90bc42-1b10-4c6f-9b58-f0e52d103907 is done by UDisks, if you want these logical volumes mounted automatically to /mnt or other "custom" mountpoint, use fstab.
