Hmm, that only accounts for 6 of the 8 drives, so something more is wrong.

leo037: The log zip you sent me says this is an RN316, not an RN428. So only 6 internal disks. Plus 5 more in the EDA volume.

boot_info.log:

vendor:	NETGEAR
model:	ReadyNAS 316
serial:	
sku:	RN316
loader:	4.6.5
board_rev:	
system_rev:	
reason:	Normal

Something is odd here, as the serial, board_rev, and system_rev fields should be populated.

Yeah sorry it is actually a 316.

Serial number I removed

Not sure why board and system rev aren't there

I don't recall where she got this one from. Could have been a craigslist or ebay find

So did the volume size increase with the second through fifth drive swap while the unit was still in XRAID? The data StephenB posted seems to indicate it did, and that would be expected. Unfortunatly, the inability to switch back to XRAID is completely normal, and I suspect the fact that the last drive isn't expand is also directly related to that.

If it did not expand at all, I cannot explain why. There may be a complex way to get it to do so by deleting all the "unused" partitions and the letting FlexRAID expand to all of them, but I've never tried that and destroying and re-creating may be best, especially since it can restore XRAID mode.

There is a complex method of manually doing the expansion via SSH. See How-to-do-incremental-vertical-expansion-in-FlexRAID-mode. But the unit will remain unable to go back to XRAID.

No. The RAID group exists (with one missing disk), but BTRFS did not expand to use it.

I think unformating and then re-inserting disk 6 will likely fix it.
