Do you have SSH port forwarded? I am seeing a lot of login attempts in the logs coming from an I.P. address in China.

Thanks, mdgm. I had set up port forwarding ages ago while I was traveling and never disabled it. My logs were full of brute force SSH attempts. (Yeah, I'm looking at you, 76.12.235.157.)

I see you are using snapshots on a lot of shares.

I disabled snapshots as well as bit rot (COW). I might enable them later if I feel like the NAS can handle it. Right now they're not necessary because I still have my Ultra 4 as a backup, and the data hasn't changed greatly.

It's possible one or more of your add-ons might be preventing the disks from spinning down.

My first assumption was Plex, but I think I've found the culprit: iTunes. Something is very, very wrong with forked-daapd based on the logs. When I finally did get the ReadyNAS iTunes library to load in iTunes, this is what I saw:



In case it's not clear, each track has seven entries.

So it looks like the iTunes service scans the media files up to a point, then there's the following series of messages:

Nov 14 21:03:31 ReadyNAS forked-daapd[1907]: main: Got SIGTERM or SIGINT
Nov 14 21:03:31 ReadyNAS forked-daapd[1907]: main: Stopping gracefully
Nov 14 21:03:31 ReadyNAS forked-daapd[1907]: main: mDNS deinit
Nov 14 21:03:31 ReadyNAS forked-daapd[1907]: main: Remote pairing deinit
Nov 14 21:03:31 ReadyNAS forked-daapd[1907]: main: HTTPd deinit

Soon forked-daapd enters a "failed state" before restarting. And the cycle repeats itself. So it just keeps scanning and rescanning. Once I disabled iTunes, I had a quiet ReadyNAS again.

Also, it looks like the logs were full of attempts to send alert messages via SMTP every minute or so. I tried setting up Gmail and Zoho accounts, but neither sent successfully. Has anyone successfully configured a mail account to send alert messages? [EDIT: Now mail alerts are working. Go figure.]
