Hello All!

I had to re-build my server.  I don't think I had my partition set correctly.  What do you recommend with the following system concerning partition sizes.

AMD 64 XP 3400
Ram 1GB
1 x 20g hdd
1 x 123g hdd
2 x 500g already in raid 0
1 x 500g usb hdd

I want to use the server for following:

1 x web server (apache, mysql php) low traffic, internal / external
2 x pptp, external
3 x ftp, internal / external
4 x syslog server (mysql, phplogcon) phpmyadmin
5 x either samba or NFS, which ever is better!
6 x backup rsysc, backup worktations to usb hdd

I *DON'T* WANT TO FORMAT OF EVEN TOUCH THE RAID!!!!!!!!!

Thanks in advance

Despite of the above message, I will recommend you to reconfigure RAID to be RAID1. You have 2X500GB = 1TB? For a web server, this is too much space without redundancy. RAID 0 could not take advantage of RAID purpose (failover) so if one SCSI drive is dead, you loose all your data. RAID1 mirror disk is different. If one drive is dead you still up and run with other drive so you can have time to replace a failed drive to rebuild your RAID 1.

Partition usage:
- Put all yours web server (apache, mysql php), either samba or NFS in RAID1
- Put all logs in 20GB
- Put backup on 500g usb hdd
- Other miscellaneous in the remaining drive

thanks for your recommendation.  The webserver is a home server nothing major.  As for the raid I did that way for the space.  In the future I want to add more drives to the RAID.  I know the raid doesn't have reduncacy so that is why I would use the rsysc to backup files I know I DON'T want to lose.  If there was a way to use raid 1 with out give up the space I would.

Am I reading you correctly with the setup below?
/var/log = 20g hdd
/boot, /, home, usr, tmp, swap = 123g hdd
/boot = 100mb, swap = 1.3g

The setup looks OK to me.
OK. If that is what you prefered, you are good to go. Question on the backup:
Assume you will have your data going up to 60% on 1 TB disk, how do you back it up to the 500GB  USB drive? What exactly do you want to backup on your USB?

thank you.

Backup: I was thinking of rsysc for backup files from workstation and files the RAID that are modified (e.g. documents)  I know that if I had used raid 1 I would have to worry about backing anything up from the RAID.  For now I'll use this til I'm able to get the space for the RAID 1 setup.

I was using Samba for sharing with Windows clients.  They would pull files to and from the RAID.  Is NFS better then Samba?

If you have windows client, Samba is the way to do. NFS is not mature up to the level that you can implement with Windows client. So Samba is better in your case.

Everything is up and running now and my RAID is intact.  K.  I'll use Samba.  I have it already installed.

I know that if I had used raid 1 I would have to worry about backing anything ....

Keep in mind that whenever you have RAID 1 implemented, you still want to backup your data. RAID 1 mirror set only works when you have 1 good and 1 bad drive. If you have 2 bad drives at a time ( I know it's odd, but it happpens sometime), you need another option which is backup.
