Ever since a reboot a few days ago (after I replaced the fan), the disks in my DroboFS have been churning pretty much non-stop. No shares are mounted and the activity light is not blinking, but I can hear the drives seeking/churning like mad, and over several days the Drobo has never idled. Top doesn’t show anything using CPU (everything aside from top itself is at 0.0%), and tools such as lsof don’t appear to be available for further diagnosis.
None of my DroboApps should be causing issues; at least, they weren’t last week. Here’s what I have installed:
Only thing that uses any appreciable resources is stgt, which is a bit of a memory pig, even when I’m not using iSCSI.
