Use fdisk to make up to 4 slices on the disk; e.g. ad0 gets ad0s1 to  
ad0s4.

you can then create up to 6 usable partitions on each slice.

if you are on 7.0 and your box is equipped for it (memory) you could -  
and probably should - give ZFS a try.
I use it w/o troubles and it really eliminates the partitioning (and  
other) hassles. Simply put: it is the next

big thing in storage ;-)

Have a look here: http://wiki.freebsd.org/ZFS

take care,
Robert

Re: number of partitions

how to do it ?
I need to create something like 16 partitions on a disk.


you may create up to 4 slices if you use slices at all (i don't)

on each you can make 7 partitions (8-one for c)

but each partition CAN be partitioned again. so you can make any number of 
partitions.


example of my home system (lots of DVD-sized partitions to make backups 
easy)

number of partitions

2008-05-15 Thread Carlo . Capponi


hello,
I would like to create a large number of partitions.
how to do it ?
I need to create something like 16 partitions on a disk.
I tryed and after the 7th partition the dev is assigned to
/dev/X

looks like I cannot create more than 8 partitions at boot time on a single 
disk.

how to overcome this problem ?
thanks

Rick
