Disk Partitioning guideline

[umeman]

I know a lot of ADMINS have a problem of a partition/slice
becoming 100% full.

Does anyone have a good guideline for the paritioning
say an 9 or 18 gb drive. Problems are mainly with /, /var,
/opt

I know one guideline - the swap partition should be 2 times the size of your physical memory

Any comments appreciated

Thanks

Besides the recommended minimum by SUN, There are no rule of thumb that I know off.
It depends on what you intend to do with that box.
If yoy plan to install a lot of softs in /usr then make / big enough to contain the softs.
If you box is a print server or mail server, you will need /var to be big enough.
If the box is a /home server then again make / big enough.


If the workstation is a standalone, here is what I do :
/ = 40 %
/var = 20 %
/export = 20 %

and I would keep 20 % free for resizing purposes..
Note that I put /usr, /home, /opt in the root /.

These are my preferences and every sysadmin has its own preferences, which means that what I do may not be the best for you.

I put /, /var, /opt, swap, /usr and /export/home on separate partitions. If home, var or usr fill up, it won't crater root. On an 18 Gb drive, I have:
/ 1.6Gb
/usr 2Gb
/var 4Gb
/swap 4Gb
/opt 2Gb
/export/home 2Gb

This is on a E420 4x4.

Again, layout depends on what you intend to do with the server.
For general purposes, your layout looks OK, the only thing is I may put 3 Gigs in /usr and 3 Gigs in /var.
One thing for sure, you have plenty of room for / since you have all separate partitions.

If your setting up a server, go with the layout nsew45 gave.
If you put /export/home in the / filesystem, ANY user whos home directory is /export/home/xx can fill up the root filesystem and stop the show.
