Try

Kind regards

Cool. Works on raid or logical volumes too:
Code:
tune2fs -l /dev/mapper/d2vg-lv1 |grep 'Filesystem created'
Filesystem created:      Tue Nov  4 15:39:59 2014

i do df -h and i see the file systems listed e.g.

[root@slcac810 /]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 48G 2.9G 43G 7% /
/dev/sda1 190M 73M 108M 41% /boot

so i do this:- tune2fs -l /dev/mapper/d2vg-lv1 |grep /dev/sda
and it doe snot work.

Could you be kind enough to give me an example that i could understand. I believe i am probably doing something really stupid that it is not working

Why not try the really clear method suggested above?

Think...

Obviously you have no "/dev/mapper/d2vg-lv1" device, so you getting an error.
You need to run
Code:
tune2fs -l /dev/sda2 | grep 'Filesystem created:'
it will show the filesystem creation date. In most cases this date is the date when system installation was started.
