Hello fellow Toaster Users,
Last night I notice that our F760 got a bit sluggish for the very first time. We are running 6.2.1R1D5. Around 1:00 when the scrub started the disk utilization went up to around 9600bB/s and no more than 300NFS ops and practically no network traffic. After the scrub completed it found no errors or problems with any of the disks. Here is a out put of a sysstat

As you can see there is practically no network traffic and very low ops. Something that dose have me a bit confused is the Cache Age... there is none? This system has been online for 400 days, 11:40 2000225709 NFS ops and I think it might just be time for a reboot. But before I reboot the system I wanted to check with fellow users to see if this is an DOT bug or just a common netapp twitch. Thanks for your help and advice.
