800G RAID5 w/ what FS?

800G RAID5 w/ what FS?

[Jason C. Leach]

hi,

I was told reiserfs does not work too well with RAID. Is this true? If 
so I'll go with ext3.  I am using a Promise SX6000 to create a 800G 
RAID5 array.

Thanks,
Jason.

I was using ext3 on a 720GB array, and now a 1.4TB array. I have no problems with it besides the 3-4 
hour fsck time when I decide to force a fsck :p)

Brad

Ext3 on a 700gb raid5 off a 3ware 7500-4lp.  Only problems I've had is
that the latency to do anything more with the disk goes sky high when
there's a lot of disk activity.

Which may or may not be related to the 700gb partition :)

well in my opinion an FS depends on what you want to do. ReiserFS is
very good with a lot of small files (maildir eg), but I only use it on
an Hardware Raid at the moment.
I have very good experience with XFS. I run it on an LVM on an
hardwareraid and on an raid5 software raid without any problems :)
ext3 is of course a save route, thought from time to time you read about
problems with ext3 and software raid. so before you gon into production
I'd do some tests :)
