8TB Drive drops out of JBOD volume on 6.4.0 on Ultra4
Hi I have 2x8TB Seagate Archive HDDs in JBOD array in a Ultra4 on 6.4.0 production. I started doing a rsync backup (this device was the destination) and after about 10min the second drive showed up...

Thanks for the clarification. Whilst I know they are technically not supported they do seem to be causing a heap of problems - https://community.netgear.com/t5/Using-your-ReadyNAS/Seagate-8TB-Archive-drives-ST8000AS0002-do-work/m-p/989048 - that seem to be worse with 6.4.0, which might be related to the new linux kernel.

Right, and it certainly doesn't appear to be specific to ReadyNAS. There are many posts about the same issue online, with an official kernel bug report still open at https://bugzilla.kernel.org/show_bug.cgi?id=93581.

Thanks.
Could you tell me the best way to get my ultra4 to 6.2.4 (currently on 6.4.0) - do I have to go back to 4.2.27 and then on to 6.2.4 or can I go back to 6.2.4 via GUI and factory reset (or do I need to USB recovery)??
Or shall I wait for a 6.4.1 (is this something Netgear will look at further??)

Back on 6.2.4 and seems to be OK. Doing a 9TB backup so we'll see...

We'll have something for 6.4.1 to try to address this. However, we don't have any SMR hard drives to test with, so we won't be able to verify the fix.
