How to make file system

[Han Tin]

 I need to make different Filesystem.
I think I have to reinstall. I do not want all in /
I want /home  as a separate Filesystem as well as to /var /usr 
Can't we split from /   to different Filesystem. I thought ext3 can do.
Thanks.

etc..etc...

It appears your space is used already and is mounted under / (root). You
could just create a directory for data1 (mkdir /data1) and begin using
it.

On many *nixes, it's been prevalent to create most filesystems in such a
way that they each appear in the output of a df command (try df -h, df
-m and others and see if you like the output better; df -k is the
default so just typing df will give the same output). Part of the
reason, IIRC, for this was that there was a limited number of inodes
available to each filesystem and if it was very big, the kernel wouldn't
be able to accomodate the potential growth.

As disks have become larger and faster, OS disk drivers and kernels have
evolved to better support them and it becomes unnecessary to create the
various filesystems.

Another reason for creating various filesystems was the belief that
performing backups was easier. I do my backups by doing a cp to a
completely different spindle mounted in a different machine. That way, I
can have incremental FULL backups going back 30 days.

Actually, I started doing this way back on Redhat 5.2 after cutting my
teeth on Slackware installed with 1.44MB floppies.

Sorry to ramble around the topic. Count on a couple others to give
better explanations.
