Some of you may remember questions from me last year about setting up a
Linux file server. Well results have been good and we have some new Linux
fans now. With that success comes new hardware. Out is my recycled
P3-500 and IDE drives and in with a newer Netfinity complete with 2Ghz
Xeon-HT and 6 15k rpm 36.7GB U320 drives.
Now the question is revisited on how to tune this sucker into a fast
reliable department server.
Use Plan: http, smb, and ftp serving of files in the 20mb to 700mb range.
Some user compiling (java) activities at times too. File serving is
really for two directories:
/staging (est. 30-40gb; basic redundancy & off-box backups)
/media (100gb; expendable convenience share, probably lone 120gb IDE drive
again )
Below is my current quick burn-in config and I have a couple questions
from it already:
1) Any advantage to the RAID0 swap partition over two disks? RAID0
performance boost make up for the S/W overhead of RAID0?
2) How does linux software RAID5 work for dissimilarly size SOFTWARE RAID
slices? See sdb vs. the rest of / members.
3) Should the OS really run under RAID5? I can afford a little downtime
to reinstall an OS; and restore config backups. I'm just looking for some
redundancy on home directories and /staging.
Current setup for burn-in:
[sda]
200m /boot
1500m md0-raid0 swap
[sdb]
1500m md0-raid0 swap
32g md1-raid5 /
[sdc]
36g md1-raid5 /
[sdd]
36g md1-raid5 /
[sde]
36g md1-raid5 /
[sdf]
36g md1-raid5 /
How would you guys slice up this box to fill our need?
Thanks.
And yes I know RAID is not backup.
