8TB Drive drops out of JBOD volume on 6.4.0 on Ultra4

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.

Thank you. If i'm feeling brave i'll try it :)

I have another 8TB drive now and in the next couple of days an RN102 should arrive. I am happy to test something if it would be helpful.

Quick related question - If one drive in a JBOD array dies do I lose the whole array or (if a new drive is replaced) just what was actually on the bad drive?? My understanding of JBOD was it should be just that which is on the bad drive is lost but other answers suggest the whole array might be lost...

Thanks

Andy

There is no such thing as a JBOD array in a ReadyNAS.

If you have one volume for every disk, then you have JBOD - all the disks are independent, so if you lose one you only lose the data on that disk.  There is no array, just a bunch of disks.

If you have one volume spanning all disks, then you have a RAID-0 array, and not JBOD.  In that case if you lose any drive, all the data on the volume is lost.

Just for followup.

Finally bit the bullet and put 6.4.2T59 on my Ultra6 with 3x8TB SMR drives in.

Just written 200GB over 40min and it's fine. No errors. No stops. No increase in command timeouts.

It looks like the fix that was added in 6.4.1 works.

Thanks all.
