ReadyNas RN104 - Trying to Attach Yottamaster FS4RU3 4 Disk RAID 5 Array via USB 3
Hi - I touched on this here: -
The problem I'm having is that whilst transferring files via My PC from a device on my Network to the attached Yottamaster it bombs out - first effort to transfer 25GB of files bombed at appx 7.5GB. When I logged into the ReadyNas, the attached storage disappeared. At this stage I unplugged the Yottamaster from the ReadyNas and plugged it into my PC . I reformatted it using Windows 11 Disk Adminstration. We then discussed the issue and I was asked whether the drives in the Yottamaster were SMR or CMR drives. I confirmed they were CMR and that's where matters ended.
After researching, to no avail, I thought I'd give it another go and yesterday set up the external Share again after plugging back into the ReadyNas. This time I started transferring 88GB files (why not?) but this time the transfer ran for 20 mins then bombed out again. Reason given in Windows Explorer was that the Destination Device could not be found. This time after logging into the ReadyNas once more, I saw the attached Share had set to "Read Only". See attached screenshots.
I don't know what to do now - I really want this attached Share to work with my ReadyNas - fwiw - I have a media player on my network and want it to play files from the Share. Before putting anything on it the player sees the "Music folder" in the first screenshot - I think Read Only wouldn't be an issue but until I can place files on it, I'm stumped.
I really hope this issue can be solved please. Thanks in advance

Did you look in the full log zip file for errors?
FWIW, a better strategy would be to expand the RN104 internal volume by investing in a couple of larger disks.
May I ask you to look at the first 2 pages of errors to see if there's anything obvious? - I really am clueless when it comes down to networking: -
You are right of course about increasing the Volume of the RN104 but another solution may be to attach the Yottamaster direct to my Media Player, but that would be if I can find room for it in my living room

The full log zip has a lot more information than you see on the log screen. But you shouldn't post it publicly, as there is some information leakage.
Most of the errors are warning you that the RN104 internal volume is too full. You should take care of that right away, as the file system can fail if you don't. If you have snapshots enabled, try deleting them (starting with the oldest). Otherwise, offload enough data to create at least 15% free space.
The only error related to the Yottamaster is saying that the RAID array might have been out of sync. As a result, the NAS made the volume read-only. If that was detected during the transfer, it would explain why the transfer failed.
The challenge here is that the Yottamaster is managing its own RAID, but the NAS itself is clearly also detecting the RAID and will therefore try to manage it itself. That control conflict will create some issues. During writes to a RAID-5 array, the NAS will normally update the RAID parity blocks and update the RAID event counters on the disk. But the Yottamaster would also be trying to do that on its own.
It might be possible to disable the Yottamaster RAID and make each disk its own volume - not sure. I'm looping in Sandshark, as he has experience with the EDA500 enclosure and I do not.
