Easiest way is to implement software RAID on your current server.
- add 2 (or more) new drives partitioned identically to your current
drive (unless you want to replace your existing drive)
- partition type is fd (RAID)
- create RAID 5 arrays using the new drives & partitions (except for
/boot which should be on a RAID 1 array)
- common setup is (but use whatever partition setup you currently have):
- /boot --> RAID 1
- / --> 20G RAID 5
- /home --> rest of space
- tell mdadm that 1 drive is missing from each array
- copy the files from each partition on your current drive to the RAID
partitions on the new array
- update grub to use the new RAID arrays
- reboot into new array
- if it works, add your original drive (or its replacement) into the
RAID array(s)
Needless to say, back up everything before starting. Creating a RAID
array is safe but mistakes happen and hardware fails.
Benefit of RAID over NAS is
- don't need to change client setups
- can be expanded by adding new drives into array
- speed on reads
- protection against hard drive failure
Google Linux RAID setup for detailed howtos.

Hi,
At my client, I installed Samba v3
on a Linux box (Centos 4) with a NT style domain to act as a file server (about 50 Windows clients).
It's been running fine for a few years now.
It's about to run out of disk space.
I was looking for a low cost solution and came across the low-cost NAS that are
available now for the soho market.
The problem is that some support only smb file access for Linux clients which for my case would be out of the question.
Some support NFS mounts from Linux host.
I wanted to have some of your comments on presenting a NFS mounted filesystem
on my Samba server to Windows clients. Do you think, I would be looking for
trouble ? I'm in a french speaking region so we're using accent. My experience
with NFS is a little bit old and I want to make sure I wouldn't loose the
french accent or spaces in filenames along the way.
Of course a direct-attached storage would be a sure thing but I was looking for
a lower cost solution.
Thanks in advance
JF Leblond
