RN2120 iSCSI Create LUN failed
Dear All,
Max LUN size available is 9.81TB
When I create this, nothing happens.
When I create a 5TB LUN, it creates it perfectly fine. If I attempt to expand this LUN to 9.81TB, it gives me an error:
### Folder operation failed.
### 21003020028
### Modifying LUN properties has failed
### Code: 21003020028
I checked the Log files and I have one entry (when the initial 9.81TB was created) which says:
### Create LUN failed (status=256)
When I attempted to expand it (after creating the 5TB one to 9.81TB)
### Modify LUN failed (status=-28)
I've tried to expand the LUN incrementally, and I can get a single LUN to 8191GB (1GB short of 8TB)
The rest of the space I have to create another LUN. I'm unable to create a single LUN.
I've tried doing this on Firmware 6.5.0 and downgraded to 6.4.2 aswell to try it, still no luck.
Any idea on how I can create a single LUN at 9.81TB in size? If not, why is there a limit?
Kind Regards...

There is an 8 Tib limit on all ARM-based OS6 NAS(including the RN2120v2). Netgear lists that as a limitation here: http://kb.netgear.com/app/answers/detail/a_id/29938/~/readynas-os-version-6.5.0 (deployment note 6)
I don't know why that limit exists, it seems arbitrary in a device that can host a 32 TB RAID-0 volume.

Hi StphenB,
Thank you for this update. I should have looked a little harder.
