On very different journalling activity on 2 servers.

[Nico Morrison <nico morrison micronicos com>]

Hello Folks,

We have 2 (identical hardware) busy public 2U rack servers, both have
several hundred users & peak email (for example) deliveries at 300/5min
during the daytime.

Both servers run RAID1 over 2 EIDE disk drives.

One server is fine - it never has problems - it is running RH7.3 and CPU
loads are normal.

The other server has constant disk activity & kjournald at CPU load of
50/60/70% most of the time!  this machine is running RH7.2

The same processes & loads are on both machines - can anyone tell me why one
machine should have so much kjournald activity & the other not?

Is it a difference between 7.2 & 7.3 or must it be another factor?

How can I find out?

Regards,
Nico Morrison
