The hard drives in my RN10200 seem to be running very often. I use the RN10200 to back up my PC. I can hear the drives being accessed often throughout the day. I have confirmed that it is not my scheduled backup jobs. I am the only user on my home network. The two hard drives are set up in a Raid 1 configuration. Should my RN10200 drives be running if I am not accessing them and they are not running a backup job? How can I tell what is running?
What do you make uf this? Disks are spinning up and down multiple times each hour.
Looks like 6 spinups in 140 minutes. Though 5 had a short spindown duration. I've seen similar stuff, the question is what is triggering the activity. There's not an easy way to tell from the logs.
But disk 1 is spinning more minutes than disk 2 (generally spinning up before disk 2). The system boots off of disk 1 normally, so that does suggest the OS is doing something.
One test you can do is to disconnect the NAS from the network when you aren't using it, and see if that calms the spinups.

The OS is installed on the disks, and there are background activities that will kick in from time to time. For instance, snapshots are created on schedule (if they are enabled), NTP will sync the time with internet time, etc.
Is disk spindown enabled? What apps (if any) do you have running on the NAS?
Thanks for your reply Stephen. To answer your questions... I don't have any apps installed on the NAS, I don't use snapshots and spin-down is set to 5 minutes.
I understand that the NAS may have small OS tasks like synching the date/time. However, the drives run for quite a while. I was hoping to find a way to learn what was running on my NAS at these times. I don't see anything on the log entries either.
spindown.log (in the log zip file) will give you some idea on when the disks are spinning up, and for how long. Though that doesn't really answer your question, it might give you some clues.
if SSH is enabled, you could run something like top when you hear the activity, that would give you a better sense on what is going on.
