I upgraded from 8.2.something to 9.1.2.1 this weekend, and have noticed that my disks no longer spin down. Something is causing constant low level disk activity on my array.
I noticed that there was an option to use the system dataset as the syslog which was added and automatically checked, I think this was causing some of the activity. Unchecking this option caused quite a few errors in the console (cannot open logfile etc), which wasn't all that unexpeted, and they went away after a reboot. However, this did not solve the problem.
Basically, even with nothing on my network using the filer I get graphs like the one shown below (ignore the bit with the read on the right hand side, something I did while ssh'ed in caused that activity).
I am pretty sure this something to do with the new samba version which also gets a dataset constantly writing to the disks...is there anyway to prevent this?
