Migrating Readynas Radiator to OS 6 Readynas devices


One challenge in migrating from Sparc architecture products, to Intel or other (Arm), is that the Linux file system on sparc was built with a 4k block size, rather than 512.

On Intel linux, if you set up your disks, you can mount them with some incantations and special procedures.  Not sure how the Readynas Linux handles that problem, but there is a link showing it.

I had a bad disk and some problems with the data recovery firmware on a REadynas NV+ some years ago and got the support group to help me get around it.  In the mean time, I had mounted the 4 drives on an Intel linux system I'd built up and had recovered most of the data.

Copy of article for archival:

This articles outlines the necessary steps to access data on disks from ReadyNAS units running RAIDiator on ReadyNAS OS 6 units.
Due to differences in CPU architecture and operating system between RAIDiator and ReadyNAS OS 6, it may be necessary to take additional steps once the disks are moved to an OS 6 chassis.
If your ReadyNAS running RAIDiator is still functional, and you can access the data, we recommended you first backup the data to another location
http://kb.netgear.com/app/answers/detail/a_id/21344
If you can no longer access the data using your legacy ReadyNAS and you wish to access the data using your ReadyNAS OS 6 device, booting may not be as easy. Depending on which legacy model the disks come from, and which ReadyNAS OS 6 you posses the steps differ to make the data accessible.
After initially moving the disks from the legacy ReadyNAS to the ReadyNAS OS 6 model please be aware of the following items;
  • Do not attempt an OS reinstall
  • Do not attemp a factory reset
  • The RAID must be healthy i.e. if the RAID was broken on the legacy NAS it will not always be possible to access the data on the ReadyNAS OS 6 - an example of this would be 2 failed disks in a 4 disk RAID 5.
  • ReadyNAS OS 6 model must have at least the same amount of drive bays as the legacy ReadyNAS
  • Logging a ticket with Technical Support may be required
  • Purchasing a data recovery contract may be required
  • You may require one additional spare blank disk
  • You may require an external location to where you can recover your data to i.e. external USB HD, network share, other NAS storage.
To find the steps needed to access the data on your ReadyNAS OS 6 device, find your model below:
  • ReadyNAS OS 6
    • ARM
      • ReadyNAS 100 series (RN102, RN104)
      • ReadyNAS 200 series (RN202, RN204)
      • ReadyNAS 210 series (RN212, RN214)
      • ReadyNAS 2120 (RN2120)
    • x86
      • ReadyNAS 300 series (RN312, RN314, RN316)
      • ReadyNAS 500 series (RN516)
      • ReadyNAS 700 series (RN716X)
      • ReadyNAS 3130 (RN3130)
      • ReadyNAS 3138 (RN3138)
      • ReadyNAS 3220 (RN3220)
      • ReadyNAS 4220 (RN4220)
Find the model of your Legacy ReadyNAS running RAIDiator, click on the link and follow the instructions. X represents whether or not your model came with disks.

Readynas Radiator 4.1 firmware problem with SMB CIFS shares


The changes made to SMB protocol from version 1 to version 3, seems to have killed the share mode of access on readynas older systems.

Switching to user share mode and creating a user is a pain as well.

But the share name is entered as a user id in passwd, but not put up as a user in the gui, which is a huge hole when you switch from share to user.

the only method of fixing it is to install EnableSSHAccess and log in as root.  One can then set an SMB passwd on the shares that exist, and each will be accessible with that passwd on system thru so far and including windows 10.

Also other secured user access is then possible once the sharing is turned on if desired.  The users cannot access others storage w/o using group access features.

Of course this has a possibility of voiding any service you have with Netgear (warranty for 4.x devices is long gone).  But if you have any service agreements, don't do this w/o checking since it may impact your agreements for unauthorized user mods to devices.

To install ssh access for 4.x radiator do the following

Download EnableRootSSHAccess for your architecture from here

EnableRootSSHAccess

Original NV+ and 1100 systems are Sparc.  Pro and Ultra systems on 4.x will be Intel.  I'm not sure if Arm has a 4.x version.  All the ones I've seen with Arm are 6.0

then:

  1. Get the SSH bin file from the ReadyNAS web site. Click the Add-ons for RAIDiator 4.1.3+ link and scroll to the EnableRootSSH link. Download the bin file and store it on your local computer.

  2. Log in as admin on your ReadyNAS using a browser

  3. Update your ReadyNAS firmware (optional). This is under System > Update. Just click the Check for Updates button.

  4. Click the Local tab and click Choose File to find the EnableRootSSH.bin file that you previously downloaded. Upload this and follow the prompts.
 A restart of the Readynas system is required, if you have other users on the device.  (since some windows systems may work).  I doubt if any samba stacks such as one would have with shares on MacOS would work, but they may be impacted.

Install instructions from here;
