I have a Ultra 6+ with Four 2TB Seagate LP drives that I migrated from my Pioneer NVX while it is being exchanged (burning odor:power supply swap). ( FWIW I love how much quieter the Ultra 6 is! )
These are XRaid2, SINGLE Redundant. From what I've read, with one drive for redundancy, I think I should be getting 3 x 2TB x .93 = ~5.5TB; I'm getting 3.7TB.
Am I missing something? I would understand this sizing if it were Dual Redundant, but it is not.
Finally - I'm pretty certain that the only way to get to the capacity I think is correct would be to get some new drives, factory default, rebuild and restore - right?
sounds like you expanded to the 2tb drives at some point and the 2nd raid layer did not finish expanding.
One of the things that can prevent that is all of the drives are not 4k aligned, ie you upgraded at different times with different firmwares.
you can download all logs and look at the partitions log and see if any of the disks have differing starting sectors, and then re-seat those drive(s) one at a time, ensuring the array is 'redundant' before removing the next.
else, you should open an online suport ticket and be prepared for them to remote in and check the device itself.
fwiw - removing the drive that had the odd starting sector, etc. and using a pc to delete the existing partitions, then re-installing into the ReadyNas for re-synching resulted in partition tables that are all the same now and absolutely no additional storage space.
I'm inclined to re-build from scratch unless there's some other idea of what could be wrong...
as a follow up, I did rebuild the array from a factory reset and still found that the volume expansion wasn't happening.
Perhaps I missed this, but I found that I had to disable the community add-ons that I've been using before rebooting to get the volume expansion to occur.
