Smart Array 3200 and Linux File systems

[Anders Norrbring]

I don't know if my problem is the file system or not, so I ask..

I have a server running on a Smart Array 3200 and 12 x 18.2GB drives.

There are 2 volumes, both are currently formatted as Reiserfs, this because it's the default in SuSE Linux.

I've noticed that the system "waits" for extended amount of time when file activity increases. That makes the system look like it's hanged, but then continue after 10-30 seconds. Can this be related to reiserfs, or should I look elsewhere?

If it's reiser, what other file system should I use for good performance?

Anders.
