[Samba] Filesystem for Samba server

[Omar Castaneda Acosta]

Actually I tested my RAID card with 2x6, 3x4 and 1x12 configurations,
the 1x12 was the fastest one (of course this is not an SCSI RAID card).

Regarding ext3, it's a journaling file system with not support at all
for B(*/+)trees indexes and metadata storage. It's based on ext2 and
it's a good way to add _journaling_ to an existing system, but not
giving any more extra features.

I checked several sources and XFS seems to be the best contestant.

Thanks for the input.

	I said ext3 because it is part of any kernel source code (hence no
patches needed when you upgrade). Though you will need patches for ACL
and extended attributes support. Also I think it is still fastest on
majority benchmark tests. ReiserFS that is part of 2.4.x kernels can
compete too. XFS, last time I checked it was noticeable slow on
writings. Things might change since then though. When I worked with SGI
Irix I loved XFS. IMHO it is one of the best journalling filesystems.
AFAIK it was invented and written from scratch in SGI. I hope the Linux
port will be soon as good as its original. 

	And yes, LVM is way to go. If you plan to grow your filesystem
eventually it will be a matter of adding hardrives, creating a volume
and adding it to a group. Then you can use standard utilities (depending
on FS you choose) to grow the partition.
