ReadyNas Duo V2 - Constantly Blinking Blue LED and Windows 11 RAIDar Installation Issues
Hi all - hope you can help me with trying to sort my ReadyNas Duo V2. I can see the NAS in Windows Explorer fine but the blinking LED is worrying me. Logging in via Firefox does not reveal any...
The problem is that you need an old version of java - which is a pain.
This runtime binary will work:
Note you can also get the runtime sdk from Oracle, but you need to create an Oracle account to download it.
This is in the second section (titled "Java SE Runtime Environment 8u202"). It appears to be a bit older than the first link (which is version 221) - no idea why that is the caes.
If you ever uninstall this stuff, you need to uninstall RAIDar first, as the uninstall will fail if it can't find the java runtime.
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: -

CMR per https://nascompares.com/answer/list-of-wd-cmr-and-smr-hard-drives-hdd/

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.
- Well looking at the table the WD2OEURX is CMR, so that isn't a problem. Any further thoughts please?
