Now bufdaemon and gbde have both ~40% cpu and on the client it says, that the nfs server isn't responding. When looking at gkrellm on the server it shows many writes on the harddisks and storcon (an configure/monitor tool for the raid controller) shows in it's cache monitor, that something is writing on the same sectors all the time. I can't write anything or read anything from the partition at that point... it just stalls also after a while everything turns back to normal operation and everything gets written ok to the disc Any ideas? >How-To-Repeat: 1. create a gbde mapping 2. export it with nfs (writeable) 3. write some GB from a client to it >Fix: >Release-Note: >Audit-Trail: >Unformatted:
