identify the drive

Hi,

I have two drives attached to the system and the system has been partitioned as below:

PHP Code:


			
/dev/mapper/system-root

                      2.0G  759M  1.2G  40% /

/dev/sda1             251M   27M  211M  12% /boot

none                  3.9G     0  3.9G   0% /dev/shm

/dev/mapper/system-home

                      4.9G  1.3G  3.4G  27% /home

/dev/mapper/system-usr

                      7.8G  1.8G  5.7G  24% /usr

/dev/mapper/system-user

                      7.8G  416M  7.0G   6% /var

I need to know in which drive does the partition / lie in ? ie, in which of the two drives does root partition belong to.

How do I find it out ? It doesn't show even in the /etc/fstab file.

vgdisplay -v
should provide clues

The 'df' should show you. Here is my system with two drives.

Quote:

df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sdb1 20350640 8800676 10516184 46% /
/dev/sdb5 151921828 12951744 131252864 9% /home
/dev/sdb6 308446680 9320076 283458412 4% /usr
/dev/sda6 137412520 50125104 87287416 37% /mnt/sda6
tmpfs 1510688 0 1510688 0% /dev/shm
tmpfs 1510688 8 1510680 1% /tmp
/dev/sda1 12396968 10102160 1665064 86% /mnt/sda1

The mounted on column shows you the mount point, the first column the partition.

Code:

pvs -o lv_name,pv_name | grep root
