RN214 - Volume data is Degraded almost every after reboot
Hello all
I'm happy owner of RN204 with 4 x WD40EFRX for some years and then I bought two used RN214.
First RN214 (NAS1) is with 3 x WD121KRYZ (all 3 new disks) and the second RN214 (NAS3) is with 3 x WD100EFAX (started gradually from 1, then 2 and then 3).
Second RN214 I had no issues while using it with 1 disk or even with 2 disks. Problems started some time after I added the 3rd disk.
Actually I'm phasing similar problems on both RN214 but more frequently on NAS3...
Almost in every shutdown & restart, intially leds of all 3 disks are active, then 1 is lost and then all 3 are active and Volume is degraded and Resyncing starts....
Which disk resyncs is also random (some times disk 1, some other disk 2, etc.). I have cleanup the box and disks from any dust, factory reset, install latest firmware (6.10.4), downgrade firmware (6.10.3), still the same.
Any ideas? Could it be power not enough for these drives? Or they need more time to initialize? Any ways to give more time to initiatialize/spin the drives prior to initializing the raid/volume?
I appreciate for any help.

I'd start by downloading the log zip file from the web ui for both NAS. Look for btrfs and disk errors in system.log and kernel.log. You can ask the mods ( JohnCM_S and Marc_V ) to analyze the log zip for you - but don't post a download link here. Instead, send them a private message (PM) using the envelope icon in the upper right of the forum page. Include a link to this thread, and also download links (google drive, dropbox, etc) to the full log zips.
Also, try running the disk test from the volume settings wheel.
Power might be an issue here. The WD121KRYZ will use more power than the WD100EFAX. If the WD100EFAX system seems to show the symptoms more, you could try swapping the two power adapters.
Thank you Stephen
I have sent PM with the logs zip to Marc & John.
About Disk Test recommendation, I will try to execute as long as Resyncing is completer (ETA 26 hours...)
Thanks

Do you think that another power supply 12V 10A would be of any damange compared to the one coming from Netgear (12V 7A)?
Like this one:

If not, I can try to buy one and see if it improves. I cannot sustain resyncing for 30+ hours all the time... And this is the best case scenario.
That one does have the proper pin-out (positive on either side of the flat keyed side) based on the label diagram in the photo. Not all do, so use care if you decide on something different. I doubt your problem is the steady-state power, it's the inrush. That a higher wattage supply will support higher inrush isn't guaranteed. You may just have a weak capacitor in your supply that assists in holding up the voltage through inrush and don't need higher overall power.
Also, be careful if they "cleverly" hide the amperage/wattage, usually by placement of the cord in the photo. They may claim to be ReadyNAS compatible, but typically aren't 7A or better. If they were, they'd advertise it.
