Partitioning The 1.2Tb Bad Boy!
Specs:
Dual Xeon 3.2ghz
4Gb Ram ECC Reg.
Intel Mobo
Intel Server Chasis
6x 300Gb Raid5 on 3Ware 9000 series controller, Hot Swap
Fedora Core 3
cPanel
This bad boy is so loud!! LOL
This is my first true hardware raid server.
Before I go ahead and get this puppy ready, I'd like your opinion on how I should arrange the partitions.
Basically, what I am afraid of is since the /home and /var paritions will be HUGE, in the case of a reboot and a forced FSCK, the machine would be down for hours ...
How should I parition my HD space to avoid 7hour fsck's .... even better, since I am running raid, is there a possibility that I will never have to do an fsck?
Also, for the ones who are wondering, if you are looking for a hardware raid controller that works with Linux, 3ware is the way to go. Adaptec has some kick *** cards but no support for Fedora. Some distro's are supported though. 3ware was a plug'n play deal for me, the driver was detected uppon install.
Thanks guys!

Also, divide it up in to several partitions, so they can be FSCK'd individually without taking all of your services down.bye

What is the server actually going to be used for? That is going to be important in determining how to partition things...

just out of curiosity what model drives did you buy? I just bought a couple Maxtor Maxline III's for my desktop 300GB each & one failed already. Reallocating sectors, reallocating, click, click click click. I'm very dissatisfied with them & probably will try to exchange them for the Seagate NL series,

This server will be used as a hosting/database server for a major site (something like paypal).
I purchased 6 seagate baracuda's 300Gb Sata drives.
I moved away from Maxtor ... seems more and more people are having problems with them.

Here is how I paritionned my drive:
swap - 8gb
/boot - 400mb ext3
/ - 3gb ext3
/tmp -10gb reiserfs
/usr -25gb reiserfs
/var -355gb reiserfs
/home -355gb reiserfs
/backup -355gb reiserfs
I went for ext3 for / and /boot since reiserfs is still considered "experimental" and I wouldnt want any trouble on those partitions
Any ideas ? I can still start over if someone knows better.
ANY input is appreciated.
Thanks.

Sheesh....
Im seeing a pattern emerge here!!
My Maxtor 200 gig starting making that awful grinding as they do when the bearings in the platter have gone......
i had it all backed up of course but I would never go Maxtor again...Veeeeryy unreliable compared to some other brands

I would stay far away from ReiserFS if I were you. I've seen it eat itself on regular occasions, usually resulting in a lot of data loss.
Just my $0.02.

you would be best using XFS and setting the drives in 0+1 for maximum performance.
you would have been better off if you got 4 Raptor 10k's in 0+1 for your database since this is going to be a "huge" site.
then run the rest of the system off of a 1 mirror.
although the 3wares have decent r-5 performance, it's still R-5 and not well suited for being used on a busy db server.

Hehe
Acutally its more like 4200 euro...
The intel case and redudant power supplies are worth almost 1000$ alone.
where do you get those incredible prices?! I want your supplier. lol
At that price, I could ship from europe and get a better deal.
I forgot to mention I had a 3 year full waranty with 24hour turnover on defect parts. That was around a grand extra. Sorry for the bad info.
Does anybody else have opinions on what filesystem I should be using here?

We have quite a few servers with ReiserFS, I have also read the horror stories, but we have not had any problems with the filesystem. The performance does seem better than ext3.

i can substitute on that part. Running reiserFS from "beta" so to speak.... works great and i had only one big flaw in all the time. And that flaw was hardware based (io manipulation thanx to my 8006-lp2 )
