mount point to disk mapping

Chris Baugh — Fri, 02 Jun 2006 02:45:20 GMT

Apologies if this is a basic question. Is there any way of reporting mount point to disk mappings, or are there any files on the system that will contain the details.

I need to check the mappings on a clients system, so don't have root access.

bdf will show ur currently mounted file systems, view /etc/fstab file, mount points in this file will mount once u will issue a mount -a command or during a system reboot.

Sorry, I haven't been clear with my question.
I know /etc/fstab will display the Volume to Mount point mapping. What I wanted was to go a step further and find the Volume to device file mapping. For example, on our development machine

Mount Point /u10 maps to Volume /dev/vg01/lvol20, which in turn maps to Device File /dev/dsk/c3t15d0

Chris,

With the following command you can see which disks belong to a Volume group:
strings /etc/lvmtab
/dev/vg00
/dev/dsk/c1t6d0
/dev/dsk/c2t6d0

With pvdisplay -v
You can see which lvols are on the disk.

Here have this - this will give you the output mountpoint:volumename:disk1:disk2:..

mount | awk '{print $1,$3}' | while read mountpt volname
do
echo "$mountpt:$volname:\c"
lvdisplay -v $volname | awk '/Distribution of logical volume/,/Logical extents/' | grep '/dev/dsk' | awk 'ORS=":" {print $1}'
echo "\r"
done

Ninad
