Need advice about resetting to Factory Default on rn104

[gdn]

So, after the 40th forced resync since upgrading to 6.4 on my rn104 (system hangs/freezes and I have to unplug&plug the power), I decided to do a reset to factory default.

My setup is the following, with two 3TB disks and two 2TB disks:

Also, the actual usage is the following, with 3.36TB free of a total of 6.35TB:

Since I don't have other external storage available at the moment, I was thinking of:

1) removing one 3TB disk and letting ReadyNas do its resync with the remaining disks (one 3TB and two 3TB)

2) reformatting the removed 3TB disk and use it as a backup disk for the data stored in the ReadyNas

3) resetting ReadyNas to factory default

4) restoring to ReadyNas the data from the 3TB backup disk

5) re-installing the 3TB disk into ReadyNas

6) letting ReadyNas do the new resync

Is this above a correct procedure? Any mistakes or better solutions?

Thank you in advance!

p.s. Logs show no problem whatsoever with the disks, but unless I use ReadyNas in read-only mode, all of a sudden it freezes and doesn't let me other choice but unplugging the power and restart.

And everytime I do so, it has to resync, and it takes about 36hours to finish.

I tried every solution on the forum, from removing snapshots to disabling apps, but nothing: it keeps freezing. Also, even if I try to "access" from different positions (l don't know the exact term), like moving some files via SMB and others via http (e.g. with the browser interface) at the same time, the system hangs after a few minutes...

I think that is quite likely. I would give the beta a try.

Your procedure won't work. RAID provides redundancy not backup.

With 4 disks in X-RAID2 (single-redundancy) you would need 3 of the disks to be able to access the data.

Have you tried 6.4.2 beta yet?: ReadyNASOS 6.4.2-T59 (Beta 1)

Can you send in your logs anyway (see the Sending Logs link in my sig)?

Happy New Year and Welcome to the Community!

Thank you for your reply, I just sent the logs.

No, I haven't tried it yet.

I read "Fix potential hang on RN104 due to a race condition when using the CPU's RAID5 offload engine."

Could be this the issue of my RN104?

Well, updating the firmware seems to have fixed the issues it had: I managed to resync in normal mode (previously, I always had to reboot in read only) and to move files without freezing
