Best way to swap drives ReadyNAS nv+ v2
I know that my ReadyNAS nv+ v2 is no longer supported, however I would like to use it as a place to store data that can easily be reproduced. I've had it fitted from day 1 with two 3 TB Western Digit...
With the help of StephenB, I disabled write cache in the new three drive setup, also opted to disable AFP, NFS, ReadyDLNA and UPnP services while I was at it.
Low and behold, this time Robocopy was able to copy 35+ GB at 200 Mbps to the NAS without any issues! So I now have Robocopy copying a lot of other data to the NAS, my guess is that whatever the issue was has gone.
After manually testing the three 3 TB Hitachi DK7SAD300 drives, I installed them in my ReadyNAS nv+ v2. Upon boot, it detected that a new install was required (it indicated an install of firmware followed by a 10 minute wait). Using RaidAR version 4.3.8, it detected the NAS on the network. I chose to set it up using X-RAID-2 with a single volume. Later that day, it performed a sync of the volume to (I think) the third drive successfully.
Next up I started copying data back from my backup using Robocopy over SMB/ethernet. Performance was reasonable at about 250 Mbps, however it stopped copying data after about 25 GB. At that point, the SMB share was no longer accessible somehow and I was no longer able to ping the NAS from anywhere in my network. I was able to gracefully shutdown the NAS using the Power button, after a reboot I was able to resume copying data.
Unfortunately, the same pattern keeps repeating itself. After copying some data, the NAS ceases to be accessible over the network again. See screenshot below to illustrate what's happening.
Any suggestions? Are there some logs I should look at? Could it be that the 3 TB Hitachi DK7SAD300 drives are not working well in this NAS? I never encountered this issue using the 3 TB Western Digital WD30EFRX drives.
Thanks.
StephenB appreciate your help here.
Any thoughts on why the NAS stops being accessible over the network after copying a (small) amount of data? I feel that this issue should be understood and resolved, otherwise I feel I should put back the original two 3 TB Western Digital WD30EFRX drives.

Download the full log zip file from the dashboard, and take a look in there for clues. If you can't sort it out, you can send me a private message (PM) with a link to the full zip. Make sure the permissions are set so anyone with the link can download. You send a PM using the envelope icon in the upper right of the forum page.
One caveat here - I've never owned this particular model, which does limit my ability to help troubleshoot.
Great will PM you with the logs StephenB! I had a look myself but did not spot something obvious.

Just want to add that this is the first time I've seen an issue where disabling the write cache made a difference, so this is certainly unusual.
