800G RAID5 w/ what FS?

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)

Regards,
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 :)
