ReadyNAS Pro Biz Edition upgrade from 6X2TB to ?
I have a 2009 ReadyNAS Pro Biz Edition that has six 2TB drives and it is running RAIDiator 4.2.22. I haven't had it on for awhile and quit using it because it filled up. I have a couple 3TB drives on hand which wouldn't be much of an addition so maybe some 4TB drives?
I read in another message string about a person doing a similar upgrade and couldn't get all his space and it was suggested he go to OS6. Without doing that, how many drives can I upgrade and to what size, i.e. 3TB or 4TB?
The message string said something about a 16TB total limit and something about increasing a volume by more than 8TB over it's original size? I don't think my server started with these six 2TB drives in it, in fact, this model originally came with 3X500GB drives which I don't think I ever used, but I don't think I started with six drives in it.
With my luck,I would like to avoid an OS upgrade. I am hoping I can do like the other guy, pull one out, put one in, etc.
Thanks so much for such a NetGear Newb

Still not getting the math. at 14TB I already subtracted a full 4TB drive for redundancy. Then what is the additional 1.3TB being taken away?
14 TB and 12.7 TiB are the same amount of actual space, just reported using different units. Drive manufacturers always use TB. The NAS uses TiB, but calls it TB (as does Windows).
1 TB = 1000*1000*1000*1000 bytes
1 TiB = 1024*1024*1024*1024 bytes
To convert 14 TB to TiB, the formula is
14*(1000/1024)*(1000/1024)*(1000/1024)*(1000/1024) = 12.7 TiB.
There are similar mismatches for GB /GiB and MB/MiB.

To use 3TB disks (or greater) you need to be running 4.2.16 or later. You're running 4.2.22 which is newer than 4.2.16 so that's fine.
Without knowing what disks you had installed when you last did a factory reset we can only guess as to whether you will run into an expansion issue or not.
You may well find you hit the 8TiB limit. If your volume capacity was 1.8TiB when you last did a factory reset you can't expand past 9.8TiB.You also can't expand a volume past 16TiB.
OS6 has neither of these expansion limitations.There isn't a way to query the box to find out what it thinks it had at reset?
Would it harm anything to swap out a 2TB for a 3TB? Wouldn't I know then if there was a gain in space?
Without bothering you more, is there an OS6 guide somewhere? When I searched for info about upgrades, etc. I didn't see OS6 mentioned.
I have since determined (I think) That I have a RNDP6350. Not sure if it is a -100 or -200? Found my original invoice and it doesn't have the model by number at all.
Thanks so much!

You could send your logs in (see the Sending Logs link in my sig) and I could probably make a guess.

You would need to swap out two (one at a time of course, wait for resync to complete before replacing next disk) before you could get vertical expansion.

It's an unsupported upgrade that you can install on your Pro. There have been several threads on this e.g. https://community.netgear.com/t5/Using-your-ReadyNAS/OS6-now-works-on-x86-Legacy-WARNING-NO-NTGR-SUPPORT/td-p/897021

The Pro Business Edition is the -100. Also the RNDP6350 is a Pro Business Edition that shipped with 3x500GB disks. We didn't ship the Pro 6 (the -200 version) with that disk configuration.
Hi guys..
I'm running a Pro biz edition on 6.5.0 and its running more or less perfect.
Started on the thread linked earlier and followed the instructions. Worked perfectly.
I have a question: which is the max space i can use with leagacy nas and os6.5.0?
i'm running 6x3TB drives today which where present when i upgraded to os 6 the first time.

Hi viperhansa,
Which Legacy ReadyNAS are you using?
Kind regards,

There are no known expansion limits with OS 6.5. There are some rack-mount legacy x86 NAS that can't handle GPT formatting in some slots. But since you have 3 TB installed already, you don't have those.
So at the moment you could go to 6x8TB if you wanted to. In practice the resync time might be a problem, especially if you use dual-redundancy.
- Sorry, but the description seems overcomplicated.
What HDDs do you actually have in the NAS right now?
"4+4+3+3+2+2-4=14", what's that "-4"??
On XRAID, if you have 2x4TB + 2x3TB + 2x2TB, you should have a RAID5 of 6 partitions of 2TB (10TB capacity, 2TB parity) + a RAID5 of 4 partitions of 1TB (3TB capacity, 1TB parity) + a RAID1 of 2 partitions of 1TB (1TB capacity, 1TB mirror), with a volume capacity of 14TB.
BUT, we're talking about RAIDiator 4.2 here, not ReadyNAS OS6! Volume creation and expansion don't happen the same way.
On RAIDiator 4.2, (I'm gonna say "if I remember correctly", just in case, but I'm pretty sure that's it, it just has some time since I played with XRAID on that version), it starts by creating the primary RAID... and that's it. After it's fully resynced, then it will create the second RAID... and that's it. After it's fully resynced, then it will create the third RAID.
It might be necessary to reboot the NAS to trigger the expansion (it is actually handled like a vertical expansion, with its limits). - Ok. I presume, that's the way you calculated the overall capacity.
4+4+3+3+2+2-4=14
You counted 4TB of overall parity.
From these 14TB, you need to count (or I should say substract), the TB vs TiB "bs", the few GB per HDD used for os and swap, the overhead due to filesystem format.
Could you post your mdstat from the logs to see where you're at in the resync/build? Or PM to me? Gotcha....it jumped from 16 hours to 3 hours, 21% to go, no drive failures yet. Will see what it says when done.
Thanks again to both of you!
