Adding new HD to existing RH 6.2 server

[Anurag Jalan <a_jalan vsnl com>]

Hi all,

I have 2x9Gb SCSI drives on my RH 6.2 server:

df output :

Filesystem	Total(Mb)	Available	%used	Mount pt
/dev/sda3	6048		2233		61	/
/dev/sda1	  54		  48		 6	/boot
/dev/sda4	2506		 670		72	/home

'free' output:

		Total		used		free
Mem:		128		79		49
-/+ buf/cache  			31		97
Swap				 0		137

Under /home I have the :

a) Unix home directories ( 20 users --hardly used )
b) /home/smbtree  ( 20 users --)
c) /home/sc_content ; /home/sc_frontend ; /home/sc_graphics
; /home/backend  ( Shared SAMBA  directories for workgroups )
d) /home/virtual ; /home/virtualssl  ( Apache web roots )

I'd like to move b) & c) ..both Samba areas tp /dev/sdb

I'd like to have your suggestions regarding:

i)  best utilisation of /dev/sdb and 
ii) file system mounting on /dev/sdb 

Thanks 

Anurag
