Hi Andreas,

On a 8.04 Ubuntu Server, its properly labelled

Filesystem Size Used Avail Use% Mounted on
/dev/sda1 461G 118G 343G 26% /
varrun 4.0G 72K 4.0G 1% /var/run
varlock 4.0G 0 4.0G 0% /var/lock
udev 4.0G 32K 4.0G 1% /dev
devshm 4.0G 0 4.0G 0% /dev/shm
lrm 4.0G 43M 3.9G 2%
/lib/modules/2.6.24-16-generic/volatile
/dev/sda5 464M 28M 412M 7% /boot

but on 10.04 Ubuntu Server, it shows as none

Please explain me the difference

Thanks,

Kaushal

Actually, I am more curious for you to explain the difference to me. As
you refer to the 8.04 names to being the proper ones you must have some
basis for thinking that?

Myself I don't see why the "device name" would matter for a tmpfs.

Hi Andreas.

Apologies,I still have not understood.

On a 8.04 Ubuntu Server

Filesystem Type Size Used Avail Use% Mounted on
/dev/sda1 xfs 461G 118G 343G 26% /
varrun tmpfs 4.0G 72K 4.0G 1% /var/run
varlock tmpfs 4.0G 0 4.0G 0% /var/lock
udev tmpfs 4.0G 32K 4.0G 1% /dev
devshm tmpfs 4.0G 0 4.0G 0% /dev/shm
lrm tmpfs 4.0G 43M 3.9G 2%
/lib/modules/2.6.24-16-generic/volatile
/dev/sda5 ext3 464M 28M 412M 7% /boot

On a 10.04 Ubuntu Server

Filesystem Type Size Used Avail Use% Mounted on
/dev/sda1 xfs 522G 645M 521G 1% /
none devtmpfs 36G 224K 36G 1% /dev
none tmpfs 36G 0 36G 0% /dev/shm
none tmpfs 36G 36K 36G 1% /var/run
none tmpfs 36G 0 36G 0% /var/lock
none tmpfs 36G 0 36G 0% /lib/init/rw
none debugfs 522G 645M 521G 1% /var/lib/ureadahead/debugfs
/dev/sda3 ext3 490M 27M 438M 6% /boot

Also I see the (none debugfs 522G 645M 521G 1%
/var/lib/ureadahead/debugfs) and (/dev/sda1 xfs 522G 645M
521G 1% /) the same on Ubuntu server 10.04, Any clue ?

Thanks and Regards

Kaushal
