Solaris

Am new on Solaris and I need customized FS like below am using text base installation iso and not getting any option to modify FS during installation .

OS: Solaris 11.3 x86

Please assist if am doing anything wrong here .

Code:

/               ->  5GB
/opt           ->  100GB
/var           ->  50GB
/home        ->  10GB
/usr           ->  5GB

Solaris 11 uses ZFS as filesystem for the root disk... Start reading here:

If you need further advice, please report back.

Thanks got this we can create FS later after installation, but what about eg. /var partition where already OS data exists and if we create new FS what about existing data .

Also is it possible to create define FS during installation .

You should really try to understand what ZFS is and how to handle stuff. For the /var mount you can chose to have it on a different slice during the Solaris installation. Please read the really good documentation about Solaris and how to plan an installation properly!

Am installing using "x86 Text Installer" iso .and not getting any option to customize FS .

There is no need to customize /var. It is always a separate file system on Solaris 11. On the other hand, /usr cannot be separated from /. Don't try to do it afterwards, you'll probably break your system. /home is automatically handled if you create local users properly. Each user created by the standard Solaris utilities is given his/her own file system, no need either to customize anything. You might have /opt wherever you want as it's not part of the OS.
