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!

I have installed the PSU. Thanks to everyone who contributed to earlier PSU replacement threads! They were helpful, and without them, I would not have attempted this repair.
ABOUT THOSE DRIVE POWER CONNECTIONS...
On the replacement PSU, there are four hard drive power connectors wired in pairs on two wire runs from the power supply. The original Seasonic PSU has these as three wire runs, each with a single drive power connector. Since each of the three drive power connectors in the ReadyNAS Pro powers two drives, it is surmised in earlier threads that it is not a good idea to run 4 drives from a single wire run from the power supply. Instead, it is suggested that the diskette drive power wire is converted to another hard drive power connector, giving three wire runs from the power supply, each powering two drives like the original PSU.
However, I cannot confirm if these three power supply wire runs all junction back to the same terminal points internally. I think they probably do, and since each drive only consumes about 10-12 watts peak, that is only 40-50 watts on a single wire run if four drives are connected. This would not seem to tax the fairly large gauge power wires.
For now, I have not converted the diskette power wire to use on one of these three ReadyNAS hard drive connectors, instead running four drives from one PSU run, and two from the other. I may make the conversion later.
HOWEVER, drive bay 4 does not work anymore! I tried two of the previously known good drives in it, and they are reported as Dead. The same drives are fine in other slots. SO, I wonder if this is related to the PSU upgrade? Did I break something accidentally? Does this in fact demonstrate proof of overload on a single power line with 4x drives, as precautionarily suggested in an earlier PSU replacement thread. If so, why is only bay 4 malfunctioning, and not one of the other 3 bays?
Note that I have the top two drive power connectors in the ReadyNAS on the two plugs of a single PSU wire run. I assume these are for drives 1-2 and 3-4, but I am not sure.
THE REAL PROBLEM THAT WAS CAUSING REBOOT/RESYNC?
Have I finally hit upon what was causing the ReadyNAS to reboot and resync? Was it because drive bay 4 was not working intermittently, and is now not working at all? Maybe this PSU swap was not necessary, only just not using bay 4? There was never any indication in the LOG files or SMART tables that drive 4 was having a problem. It would just suddently reboot and resync.
Meanwhile, I successfully rebuilt an XRAID2 array using 3x2tb drives plus 2x4tb drives. I am now doing a partial mirror copy test from the new NAS, and so far it has not gone into reboot/resync, which it would have already done before with the amount of data being moved. For extra cooling during this copy, I am running a small box fan into the drive side of the unit with its door open. Drive and CPU temps are reported in the 80s, which is low. This is just a little insurance in case overheating was an issue before (I don't think it was.)
Assuming this first, partial batch mirror copy completes without failure, I will consider the unit useable as is.
I may modify the drive power connection wiring, and add a 4tb drive to bay four when the volume begins to run out of space. Worth a try, and can't hurt anything?
Oh, almost forgot to mention, during the PSU swap, a small metal cooling fin fell off a chip on the bottom left corner of the motherboard. I reattached that, and now wonder if the cooling fin was not doing its job with full efficiency before, leading to that chip overheating and malfunctioning? This is yet another unknown in this DIY repair saga.
By the way, I think the new, forum-approved bandaids and bailing wire look rather spiffy on this old-boy NAS, which I want to keep chugging along, trouble free, for another few years. I hope I don't soon post here that the darn thing is rebooting/resyncing again. Fingers crossed!
Cheers,
Ear-Relevant
Have they changed the wiring, or did you not get the Seasonic? All of the Seasonic's I have gotten have two wire sets with 2 4-pin Molex and one floppy connector each and one dual SATA. I have always cut them all shorter and replaced the connectors with the 90° ones from the original, as it makes the installation a lot cleaner. I don't recall if I measured to see if the three connectors were common on the backplane, but I suspect that they are.
You may be right about slot 4.
Sandshark,
Thanks for your comments and support in this thread!
Yes, I got the OEM Seasonic from Newegg, and it has the two wire sets with 2 4-pin Molex and one Floppy connector.
I used both 4-pin Molex from one wire set, and one from the other set.
I may eventually use one of the original 90 degree Molex connectors, with the slip-off cap over the easy push-in wire connections, to modify the floppy connector. This would giving one wire set per 2-disk connector in the NAS like the original setup. As I pondered in my previous post, I wonder if it is actually necessary in terms of power distribution. Like you, I suspect they are all internally on a common rail, so why bother with the modification? I think those PSU power wires can handle a ~50w load.
With today's large drives, if the rest of the NAS keeps running smoothly, the loss of a single drive bay is not a problem.
I ordered a new PSU.
I recently updated the BIOS, as it was still running the 2008 version.
I then did a thorough drive test using the boot menu option. No problems found.
So, I tried doing a big copy and the NAS soon went into the same reboot/resync cycle.
Next, I pulled the two 4tb drives for which I had the nagging concern were not compatible since the SMART tables reported grossly inaccurate total hours used along with a few other parameters.
Anyway, it quickly went into another reboot/resync while trying to rebuild the smaller 4x2tb XRAID2 volume using known good drives that are specifically in the Netgear drive compatibility list. So, I figure it isn't a disk problem, and even with the reduced PSU current demand when using 2 less disks, it still goes into reboot. Of course, it could be the CPU or motherboard, and not the PSU.
I have already setup a new NAS. I would like to use this older ReadyNAS Business Pro as a remote backup/mirror, giving me a more complete backup solution.
I will post the results of the PSU swap.
Moderators? Anyone?
The battery provides power to the real-time clock (RTC) when the NAS is not otherwise powered. That won't be causing your problems.
Can you post the SMART stats for the ST32000644NS?
Also, can you download the log zip file, and look in disk_usage.log? Please post the line that starts with /dev/md0

I have never changed the battery (CR2032?).
What does it backup?
Could a dead battery be related to the problems I am having?
Thanks!
The exact model number for the Seagate IronWolf 4TB drives is ST4000VN008-2DR166. I previously stated ST4000VNB08.
Here is the SMART info for each. Note the Power On Hours, Head Flying Hours, Total LBAs Written, and Total LBAs Read. As you can see, those can't possibly be accurate since these are new drives and I would need to be extremely old to put that many hours on them, Ha Ha!
