Better, specially for a first timer, to allocate the entire space
available after sizing swap as one, single / partition.

The installation requires substantial space in /opt and /var, which with
your little 1 GB / partition rapidly uses up available space.

Better still if Solaris 10 isn't required, use OpenSolaris and get ZFS
boot. No more slices to worry about.

ZFS is not actually required for my disk of 80GB i believe. I think ur
talking about GRUB boot loader.

hi dave, So could you please suggest how much space should i keep for
root. Coz i want to create a seperate slice for / and /usr and
thought i will create slices for /var and /opt seperately after
installation

ZFS is not "required" for Solaris or Solaris Express, but if you install
OpenSolaris your Solaris partition will be ZFS and you have the option of
installing Solaris Express (recent releases) using ZFS. It is called "ZFS
boot" because your boot disk is ZFS, regardless of its capacity.

This particular system has OpenSolaris installed in a 27 GB partition.

$ head -1 /etc/release
OpenSolaris 2008.11 snv_95 X86

Solaris 10 has filesystem logging enabled by default. There is no good
reason for creating separate partitions. You are attempting to create
problems for yourself, specially with the tiny amount of disk space you
have allocated for Solaris.

Just FYI, here is the usage on one Solaris 10 u5 amd64 system from du -sk
executed in /:

1 bin
76299 boot
1 cdrom
428 dev
118 devices
70078 etc
357322 export
0 home
91635 kernel
25269 lib
8 lost+found
0 net
599410 opt <== I don't even have the Studio 12 compiler installed
33396 platform
2427579 proc <== not actually disk space used
1606 sbin
6351 system
32 tmp
2883180 usr
4354712 var
0 vol

Note that /var will keep growing as patches are applied.

There are reasonable conditions for chunking up filesystems like that,
particularly /var... but none of them really apply to a person just
learning on a personal workstation. (And like Ian said, ZFS will make
it ALL pointless...)

Give slice 1 (swap) a capacity of roughly equal to your RAM size or 1G,
whichever is greater. Give all the rest of the disk to /.

Having /usr, /opt and / in different file systems today is counter
productive, it is legacy to do so.

For workstations, development I use:

/
swap (1-2 times physical memory)
(nothing more unless SAN/3-8disks quantity is required, then /apps)

For servers I make a choice. I actually might go with the workstation in
some circumstances but very often go this way:

/
swap (1-2 times physical memory, adjusted based on development)
/var
/apps (where applications go, and may have more underneath)

Root / gets all the primary disk space not used by swap. Period. I tend
not to share that with applications where I have more than 2 disks (*always
mirror root). If an application is tame like DNS/Bind, I will share root or
/var. But if a 5TB DN I tend not to share, not even logs/redo. I never put
the / or /var on externally attached disk unless there is no other option.
More than once I have had to troubleshot a FC SAN issue and it has been
instrumental in getting the SAN people to come around.

No I'm not (who's this 'ur' bloke?).

ZFS is never required (well OK, it is for Sun's OpenSolaris
distribution) but its much easier to manage. My laptop has an 80GB
drive and it certainly uses ZFS boot.
