Expansion failed - Pro Pioneer 6

Question

Hello -&nbsp;Adding a 6th HDD to this Pro Pioneer failed. &nbsp;I believe that this was built using 4 each 4TB HDDs and later adding a 5th and now attempting to add a 6th. &nbsp;Is the issue a&nbsp;8TB expansion limit? &nbsp;I will happily upload logs, but don't see how to attach the file, or add a&nbsp;download link. &nbsp;The drives are&nbsp;WD40EFRX. &nbsp;The other thing to observe is that the volume was very full before attempting the expansion. &nbsp;If that's an issue, I can free up some space first.&nbsp;Thank you!&nbsp;Hostname:Ascent-PioneerModel:ReadyNAS Pro 6 [X-RAID2]Serial:20S40CRL00187Firmware:RAIDiator 4.2.28&nbsp;Memory:3072 MB [4-5-5-15 DDR2]IPv4 address: 1:Not ConnectedIPv4 address: 2:192.168.1.4Volume C:Online, X-RAID2, 6 disks, 98% of 14 TB used

There is an 8 TiB growth limit, but you didn't exceed that.
&nbsp;
The problem is the other constraint on growth - a volume cannot grow over a 16 TiB size. &nbsp;After 5 disks you were at 16 TB (~ 14.5 TiB), the 6th would take you to 20 TB (~ 18.1 TiB).
&nbsp;
What you can do is back up all the data and do a factory reset with all drives in place. &nbsp;Though the volume can't expand to more than 16 TiB, the NAS will create a 20 TiB volume if you do this.
&nbsp;
Since you are facing a factory reset anyway, you could take the opportunity to switch to OS 6 - which has no known expansion limits, and which has other features that aren't available with OS 4.2. &nbsp;One thing to factor in - you will lose Netgear support.

Ok, I'll consider a factory reset and OS 6. &nbsp;AFAIK, the 4TB HDDs I am using is outside Netgear support already. &nbsp;(?)&nbsp;Can you point me to directions for upgrading to OS 6?

The legacy HCL aren't updated very often. &nbsp;Though the pro pioneer list does include three 4 TB models, including both WD Red drives and the Seagate VN drives (now branded as "Ironman").

&nbsp;See the highlighted post in this thread (&nbsp;https://community.netgear.com/t5/Using-your-ReadyNAS/OS6-now-works-on-x86-Legacy-WARNING-NO-NTGR-SUPPORT/m-p/897023/highlight/true#M50465)
The cliff-notes version is&nbsp;
&nbsp;
1. Install&nbsp;the add-on&nbsp;PREP4TOR6_0.1-x86.bin. &nbsp;Don't reboot.
2. Install the firmware R4toR6_latest.bin3. Reboot
&nbsp;
The reboot will automatically trigger a factory reset, which of course destroys the data on the NAS and the configuration.

How robust is the OS 6 on a Pro Pioneer? &nbsp;As a casual user, I have no real complaints about the current OS...and often subscribe to the "if it ain't broke, don't fix it" logic. &nbsp;Although my Pioneer is out of warranty, its possible that I talk to Netgear suppor someday, although this forum is my first stop. &nbsp;FWIW,&nbsp;I&nbsp;do have OS 6 on my 2nd ReadNAS (RN316).&nbsp;The WD40EFRX 4TB HDDs I'm using in the Pro Pioneer are now included in the compatability list.&nbsp;Thanks!

&nbsp;

I also have a mix of OS 4 and OS 6, and am not in a hurry to switch my pro-6 over to OS 6. &nbsp;When I need to do a factory reset for other reasons, I'll look at that option.
&nbsp;
Overall posters here generally feel that OS 6 runs quite well on their legacy NAS. &nbsp;One weak spot seems to be fan detection and control. &nbsp;You can deal with fan control issues via overrides (using ssh), but that won't work for fan detection problems. &nbsp;Netgear has resolved those issues in the past (despite "no support").
&nbsp;
BTW, if you do proceed you might take a look at the bios version you are running. &nbsp;It would be wise to have the latest bios installed before you migrate (the add-on for that doesn't work with OS 6).&nbsp;
&nbsp;
I think the most recent bios for the pioneer is here:&nbsp;http://www.readynas.com/download/addons/x86/4.2/BIOS_Update_Package_0.5-x86.bin &nbsp;But maybe wait for&nbsp;mdgm-ntgr&nbsp;to confirm...
