Constant Disk activity RN104 w/6.1.8
My "activity" light NEVER stops unless I turn off the power. NEVER. I usually run MYSQL server (for the XBMC database) and the NAS holds my video files. The XBMC accesses the NAS via NFS. Respo...
I believe I can recognise disk activity when I see and hear it...
I have two ReadyNAS 104 boxes, both with two 4TB drives configured in X-RAID2 as per default. FW version is 6.1.9. One box is just sitting there quietly, showing no significant disk activity unless I access it. The other one is frantically working 24 hours a day. The disk activity LED is blinking all the time and I can hear the drives rattling. What I can't work out is what it's doing. Nobody is accessing the box. A network trace reveals nothing more than an occasional NTP or SSDP packet and such like - nothing that might correlate with disk activity. The disk activity continues even when I pull the network cable. When I reboot the box, things remains quiet for a few minutes after the box comes back up, but then the disk activity resumes. There is no indication of anything happening in the log, except the daily snapshots. I'm not running any extras. I've experimented with backup jobs and cloud backup, but I've turned all of that off.
I don't know exactly when this behaviour started, but it's now been going on for perhaps 10 days. I've had the box only for 2 weeks. In the first 3 or 4 days, I copied 1.7 TB to it. Since then, the box has been idle except for the occasional test. What might explain the contrast with the quiet behaviour of the other ReadyNAS box? This other box has only 500 GB on it, and it's had them for perhaps 2 months.
I don't know if the unexplained disk activity affects performance or has any other unwanted effects, but if it is going to go on, I'm worried first about my electricity bill, and second about the life time of my hard drives.
