Besides, unless you have GigE or faster network on that server, you won't gain much performance from raid5.

Compression will let you store more, but making it a bootable disc is worth more by turning it into a custom tailored rescue disc.

But doesn't need to be on a raid array... got an old 20GB drive kicking around? This is a partition that can be lost without losing all that much hair ;-) $umount /tmp; mount -t tmpfs /tmp is a quick fix for when it does fail. Addtionally, just four more small points here: ext3 v.s. reiserfs v.s. other FSs.. these can start holy wars, but what I do is use ext3 for relatively static data... reiserfs for when there are a heck of lot of files (big and small files) e.g. ext3 for /, /usr, /opt and whatnot, reiserfs for /home, /var and anything which has a large amount of code source (/usr/src for e.g.) Also, you don't _have_ to add whole drives to a RAID array.. but it makes it a lot easier when setting it up and hard drives are pretty cheap. If you do set up swap on a system with two or more hard drives (raided or not) split the swap partition into two and mount both with equal priority... e.g. $ grep swap /etc/fstab /dev/hda2 none swap pri=0 0 0 /dev/hdc2 none swap pri=0 0 0 In single user mode, with only / mounted, chmod 000 /home /var and the other mount points. It helps avoid silly mistakes (yours or others'.. myself included). -Phil ---- philip [ at ] orpen [ dot ] com (Pgp: 0xB578851A) Freelance Linux Technician (Need Help?)
