Sometime tonight my My Book Live Duo 4TB front LED started blinking as if there is a lot of drive or file activity going on. Except, there isn’t.
Went in to front end interface. Showed red exclamation, “System has restarted” with a timestamp of May 15, 2013 (10 days in the future)!
Did not get any e-mail events from the drive.
Remote access is disabled.
DLNA and iTunes are disabled.
Under “Share List,” “Media Serving” is all off for all shares.
Drive is configured as RAID1 (2TB). RAID status is “Good,” both drives also show “Good.”
I ran “Diagnostic”. It hung at 90% for 10-15 minutes, then passed.
Everything in the web interface seems to show that nothing unusual is happening. Drive status is “Good.”
I can browse the drive, and do small file transfers. Large file transfers hang after ~10-20 megs.
Tried to create and save a system report, that also looked like it hung, but it eventually saved after several minutes.
Looking at the logs, it appears that the system has started some sort of RAID data redundancy check.
I noticed that the last event in the daemon.log file is:
May 5 03:12:11 MYBOOKLIVEDUO mdadm[3918]: Rebuild20 event detected on md device /dev/md3
That is the only “Rebuild20” event in the daemon.log file.
Why would this be happening? Is this some automatic process? Is there a way to configure it? Why isn’t the status of the drive showing that this test or check is happening, since it’s adversely affecting drive performance?
Have not tried rebooting yet… I’m afraid it might cause data loss.
Here is is the daemon.log and process_list from the system log zip file.
Here are the entries from process_list that are using CPU:
