NAS RAID 1 performance and free space percentage
Hi, We have a RR4312x0 using Flex raid. Two of the disks are RAID 1. The logs report that they are below 20% free and therefore performacnce will degrade. What is the safe percentage level? This RAID 1 volume is home to an iSCSI LUN so I was hoping to use its entire capacity for the LUN. If I need to reduce the LUN size then so be it but I'd love to know how much space of a 2TB volume I can give to it. Also, can I tie an iSCSI LUN/group to access from only 2 calling IP addresses? We have a WIndows Hyper V HOST that is direct connected via the SFP+ ports. This windows iSCSI initiator HOST is also on the same LAN as the 1Gb LAN ports that the business devices connected to the NAS SMB shares via. I need to stop this as it could potentially slow the link down. The iSCSI LUN holds Virtual server VHDs so speed is crucial.

Hi, I have access the NAS via SFTP & SCP. Where in the file structure is the actual LUN file so that I can copy it off the NAS for mounting elsewhere. We have a iSCSI partition that will only be seen as RAW by the iSCSI connector in Windows and we need to see if it really is totally damaged, The data\LUN folder appears to be empty. Thanks!

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...Solved3.9KViews0likes3Comments
Occupied size by a Thin lun
Hi, I want to know how can I determine the occupied size for an instanced Thin lun on my RN104. It's possible with a command by CLI? The host is a Windows 8 and the lun was formatted on ntfs. The ReadyNas version is 6.3.5 Thank you in advance for reply. Regards, Francesco.3.3KViews0likes4Comments
