ReadyNas Duo V2 - Constantly Blinking Blue LED and Windows 11 RAIDar Installation Issues

100% perfect - thank you! 

Yes the download for Java was not amongst the ones I tried - guessing that RAIDar doesn't work with 64-bit Java.  Anyhow I can now "setup" my Duo v2.  Also RAIDar 6.5.0 works now too with my ReadyNas RN104 - further result  👍. 

May I ask a further question please?  I have just set up a separate 4 disk RAID 5 array (4 x 2TB), non-NAS, which is working perfectly attached to my PC.  If I want to see this on my Network, will it be a simple case of attaching it to my ReadyNas RN104 using one of its USB3 ports?  Or is there some configuration needed?  Thanks - your answer will determine which way I'll go with my Duo.

I appreciate you sticking with me, very much appreciated.

No, that won't work.

You can of course share the storage as a network share from the PC

Ha - I've been fiddling around.  Connected it to the RN104 logged in through PC and configured it just as I've done with my other Network Shared Folders, albeit it shows up as an external source.  Currently transferring some Photos and Videos to see if a Media Player in another room picks them up and shows/plays them.  If it does then my rearranging of all my storage will commence in earnest.   I'm transferring via my PC now, which is usually off when I use a media player, which are situated in another room

Nope!  Transfer - appx 24GB started well but bombed out and now it's asking for Windows Credentials: -

So what now?  Obviously tried the credentials associated with my NAS - not seen this before.  And why did the transfer start but then bomb about 5 mins later?   Windows Explorer is also preventing me accessing, again with this request

Normally it will do that with a normal external hard drive, but not with a RAID array.  Just guessing here, but you might have a SAN solution with hardware RAID that looks like a normal USB drive to the NAS.

You could enter the NAS admin password and see what happens.

Most any USB(3) DAS RAID array (which is what it sounds like you have) will work fine with an OS6 ReadyNAS as an "external USB drive".  The problem is that most such devices come with some sort of administrative/maintenance program to use with it and monitor it's health, expand, etc., and that won't work ion that configuration. So step one would be to plug the unit back into a PC where you have access to that program and can check the health of the RAID.  One of my initial attempts at backup for my 516 was a Drobo DAS.  It worked fine, but I didn't like not having access to anything to show me the health of the unit.  I ultimately determined a second NAS was the right move.  Of course, a 104 is far less capable that a 516, and memory and CPU time could become an issue with a very large external array.

Some here have reported issues with large external drives (not even RAID) and large files, and it sounds like you may have a similar issue.  Unfortunately, I've not seen a solution or even a work-around.  Most seem to just keep trying and either it finally (for reasons unknown) works or they give up.

I've tried entering the ReadyNas's credentials to no avail.  You said: -

"Normally it will do that with a normal external hard drive, but not with a RAID array.  Just guessing here, but you might have a SAN solution with hardware RAID that looks like a normal USB drive to the NAS."

Can you explain what you mean exactly.  Are you saying I cannot attach a Raid Array (it's a Yottamaster) to the RN104?  What do you mean by "SAN" solution?

I've just logged in via 2 browsers both accepted the ReadyNas Credentials but sadly  the "External" USB HDD does not show.   In Windows Explorer Explorer after disconnecting from the RN104 and back into the PC what was supposedly transferred previously before the transfer bombed out is not available to view, resulting in me having to reformat as a normal HDD - am currently back to where I was before connecting the Yottamaster to the RN104.

I'm troubled now because I cannot log into the RN104  via  Windows Explorer.   Thankfully my Media Server is seeing the Shares.  Any thoughts how I can get Explorer to work again please?  Sorry for this, just thought I could connect the Yottamaster

Yes - I'll give up on attaching the Yottamaster - but how do I login again with Explorer?

Ignore Guys - a reboot of my PC and the RN104 has restored matters to how they should be.

FWIW, I haven't installed any Yottamaster software - the RAID mode is selected using a combination of 5 rocker switches on its reverse and I initialized and  formatted via std Disk Administration in Windows.  I still cannot understand why everything worked correctly at first then went pear shaped after I managed to transfer 7.5GB of data before it bombed.  Ideas?

How was the storage formatted?  exfat? NTFS, something else?

Are you connecting it to the RN104 front port, or one of the rear ports?

It was formatted NTFS

Used one of the rear USB3 ports

Are the drives in the Yottamaster SMR or CMR?  RAID is going to slow things down, anyway, and even more so with SMR drives, especially with large and/or continuous file transfers.  The 104 is very memory limited, and drive buffering may be an issue if the unit is slow to respond.

BTW, a "SAN" is a Storage Area Network.  That's networked "bulk storage", usually access via iSCSI.  What you have is a DAS (Direct Attached Storage).

I really haven't a clue - never heard of this distinction.  These are the drives: -

Something you should be aware of.  Many drives in the 2-6 TB class are SMR (shingled magnetic recording).  These drives don't behave well in ReadyNAS (particularly OS-6 systems), and often don't perform well in RAID generally.

The issue is that sustained write performance with this technology is very poor.
