ReadyNAS Pro rebooting and resyncing, with file copy hangups and other issues
I have been using a ReadyNAS Pro RNDP6350-100NAS for many years as a home music server (Logitech Media Server) and backup for my PC and data files. Firmware is 4.2.30. It has not been 100% stable for some time, often hanging on a file copy or other processing activity involving about 200 MB or more. I use Windows 7 Professional with its Explorer file manager, and usually have to Ctrl-Alt-Del to get to the Task Manager Applications list to End Process to stop operations that will not complete. The odd thing to me is that after 2-3 rounds of this brute-force intervention at the beginning of a session, my system would run stable for all or most the rest of the day. Then, it would occur again after I haven't used it for a while. The last year or so, it has been close to only 10% remaining space in the volume. I had been using auto spindown after 30 minutes, but recently increased the time to 60 minutes. Now it reboots often and sometimes resyncs, mostly during drive activity but sometimes by itself. I recently expanded two of six disks from 2tb to 4tb, using Seagate ST4000VNB08 Ironwolf drives to replace drives with reallocated sector and command timeout problems. The volume expansion occured as normal after rebuilding with the second 4tb disk, but then it resynced about three times before seeming to be stable. It has since resynced a couple more times in the past few days, but mostly it just keeps rebooting when I try to use it. Having a look at the logs, in the past I think it has been rebooting more than I realize because it is in a separate room and I don't hear it. I don't see any problems with the current set of drives as indicated in the Frontview Smart info tables for each drive. Today I took apart the chassis and unplugged and replugged each of the power supply (PSU) connectors a few times to see if there might be corrosion building up, possibly causing the rebooting and other problems I am experiencing. I also did a thorough vaccum. So far, this has made no difference. I ran four memory test passes yesterday, with no errors for the 3gb memory (both slots in use). I wonder if the ST4000VNB08 drives are supported? They seem to have had the normal Seagate model # updates to the original ST4000VN000 that is listed on the Netgear ReadyNAS approved list, which says this drive "should" work. Regardless, the unit has not been 100% for some time, so I am not sure whether the new drives have created any of the more recent problems. I recently ran an offline file check and data scrub without errors. At this stage, I wonder if it needs a new PSU, or if there is a software fix? I'd rather not get a new unit, but I realize these things don't last forever. Fortunately, I have a recent, nearly 100% backup, spanned across multiple USB drives. Comments and suggestions much appreciated. Thanks! Some Recent Logs: Mon May 22 19:04:27 EDT 2017 System is up. Mon May 22 18:02:04 EDT 2017 System is up. Mon May 22 17:44:59 EDT 2017 System is up.
