RNDP4000 - ReadyNAS Pro 4- How to change all discs with larger discs and mantain all data and obtain
Hello to all My ReadyNas Pro 4 (RNDP4000) has OS ver 6.10.3 and module of 1024 Mb system RAM. I need to replace the current four 3 TB disks with four new 12 TB disks to obtain a new larger volume ...
That expansion method would be the best option, expanding the drives one by one and waiting for it to finish resync and then proceed with another.
Here are a few links for more information.
Regards

I'd upgrade the RAM to at least 2 GB as part of the project. Some folks are starting to seeing out-of-memory issues on their legacy systems. Currently shipping OS-6 NAS all have at least 2 GB of RAM, so that should be a safe amount.
Hi Stephen,
I gave an incorrect indication, I had already installed the 2GB of ram when I updated the Readynas to OS6.x.In this regard, I ask to you where I can see the system ram installed in the administration pages of GUI interface?Thanks. Bob

One thing to remember is that you should insure your backup is up to date before doing this. Replacing the drives one by one will put the most stress on them, and a drive near failure may be pushed over the edge. With RAID5, the loss of one drive while another is syncing destroys the volume. Note that each old drive becomes out of sync as it is replaced, so you don't have the option of going beck to the old drives if you find later that you should have made a backup.
