ReadyNAS not showing all disks
I have a readynas 428 with 4 8TB disks in raid 5 with X-Raid enabled. The overview page shows the correct amount of space is available. The front panel shows the disks are there. The volumes tab however only shows a single volume as does the performance tab. I'm not sure how to make the other volumes appear. I did try a complete factory reset which seemed to change nothing. One thing I think is a little suspicious is that the disk information displayed on the front panel says they are on channels 1, 0, -1, and -2. The admin pages shows the channel 1 disk. How can I get it to display my disks correctly?
Just so I'm sure I got it right, you started filling the bays from the bottom, so the picture with just a drive in the top bay is completely wrong -- there isn't one there and there are 5 in the lower bays. Correct?
Disk_info.log identifies the channels as 0, -1, -2, -3, and -4. It comes from the Netgear program rnuitil, though I'm not sure where it gets the information. So it's not just the GUI that's confused. Controller channels are normally assigned based on the bay, not sequentially as you add the drives, and do start with zero. Why yours appear to be labeled from -7 to 0 instead of 0 to +7 is certainly a puzzle, but does probably explain why the GUI isn't showing them, as it doesn't know what to do with a negative controller channel designation. Since you started with bay 8 (controller channel 7), it should be showing them as 4 through 7. The drives themselves are also normally labeled in the GUI based on the slot, but starting at 1 instead of zero -- so the controller channel +1, which is how yours are showing as +1 to -3.
While we normally recommend that you leave the drives in the same order, the system is supposed to sort everything out regardless. I'm thinking that maybe that sorting out will assign the right channel numbers. I suggest completely reversing the drives and start from the top bay.
I'm assuming this isn't just a bug that only shows up in a 428, but it would be nice to hear from another 428 owner to be sure.

That is totally normal.
You have a single RAID volume that spans all four disks.
I expect to see one volume, but I can only see one of the four 8tb disks that make that volume. I have other earlier readynas models that are configured the same way but show all four disks that make the single volume. I've attached a screen shot showing the incorrect page, hopefully that clarifies.
While I know of no reason the sync would cause that, I suggest you wait till it completes and see if it just fixes itself once the OS is not as occupied in the sync.
