RNDU2000 on OS6 : max hdd support, memory support, changing the ethrnet+USB card
Dear ReadyNas users, I have an old but still reliable RNDU2000 migrated to OS6 (it was delivered with radiator V4.2.19). Memory was upgraded using a 2Gb Sodimm Kingston KVR1333D3S8S9. Current conf...
Hello Stephen, thank you for your answer. Everything is clear.
I will probably try with seagate 8Tb and let know. (Hope it will work because they are quite expensive..)

Note that you can migrate the disks to a newer OS-6 x86 NAS with no problem.
If I understand correctly, a volume can be taken out of an OS6 Nas and insalled in an other OS6 NAS. Correct ? But I suppose we have to change all disks. Can it work for a 4 bays NAS, with 2 bays already installed, and we bring 2 new disks already formated ? I suppose not..
Regarding swapping out the Ethernet/USB riser card, no, you cannot upgrade it. It does not include all the harware that supports the interfaces, it mainly provides the physical connections.
Yes, you can move all drives from one OS6 NAS to another, including legacy.
Under specific circumstances, you can move the drives from one NAS to another that already has drives installed and a volume exists.. I have gleaned this information form a number of experiments I have run, so I cannot gurarantee I have determined evey possibility.
- The volumes cannot have the same name. So, if you let XRAID format both volumes, they are both named "data", and you cannot combine them. There is no provision to re-name a volume.
- You also canot have any shares with the same name, but they can be renamed before the export to not match any on the other volume.
- I think user folders are exempt from item 2 because you lose the personal folders on the moved volume. While you lose access, the contents are not removed, AFAIK, so they just take up space unless you know how to go into SSH and fix that. Best to remove contents before the export.
- Ditto #3 for apps.
- You must do an "export" of the volume being moved before moving it. You set the other NAS to flex-RAID and then install the exported drives with power off. An import occurs at power-on. Note that once exported, a volume cannot again be made into a primary volume, it can only be added as secondary to another. (Well, there is a round-about way to make it one, you add it as secondary, then destroy the primary. Doing so does not recover apps or user folders that were once on it.)
Thank you for the detailed answers.
So no improvment possible on memory and connection side.
Next step for me is to try a ST8000NV0022 ; I will let you know if it works.
Hope the voltage issue is closed with the removed drive.
Have a good day,
I do not know if the Ultra2 has an internal 12V regulator or relies strictly on the 12V from the power brick. I rather suspect it has no true regulator, maybe just a zerner clamp in case of a power brick failure. If that's the case then either your power supply is overloaded (perhaps by the drives), the brick is failing, or the circuitry that monitors the 12V is failing. Maybe see what happens after you swap out the drives.
If the problem persists, replacement 12V power bricks are easy to find. I recommend one rated for cctv cameras, not LED lighting, as they tend to have better regulation. Couldn't hurt to bump the rating a bit to 6 or 8A.
