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 how...
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.
Perhaps I put the first disk in the highest number bay, and it got the channel 1 value, and the subsequent drives got the delta from the decreasing bay numbers added to the channel? I'll wait for the resync to finish and try reordering them, and let you know. Thanks!

So I can now confirm that what fixed this for me was powering off, removing all the disks, and reinserting them in the opposite order starting from the top bay instead of the bottom.
Many thanks to everyone in this chat that helped!
Great. This sounds like a bug, but at least we now know a work-around.
