novell current disk requests constantly 1 slows whole network
We run a novell 4.1 mirrored servers which i know nothing about the guy that used to fix any problems i had has vanished.
Everything was working fine untill all of a sudden even when they are the only machines turned on the "Current disk requests" is permanently on 1 and the CPU is madly fluctuating betwen 30 to 70 % utilization and then the whole network grinds to a halt.
I have tried to find a pattern but haven't as yet.
If i restart the the servers it can be okay for a while but not sure what triggers it.
What confuses me is what would the constant 1 "Current Disk Request" be
Also the hard drives lights on both the pairs are flahing away madly but what are they doing ?
