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.
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.
The sync is a complete red herring, it was like this before I added another disk, before the sync started. Something else I just noticed is that the disk in the volumes view and the same disk in the status view (I've attached another image of that) list different channels for the same disk, 1 and 0 respectively.
Has it always been that way? While I certainly expect you've done so, please confirm if you've done a power cycle and it behaved the same afterward. If it's not always been this way, do you know if it started when you did a power cycle, OS update, or anything specific?
The 1 vs. 0 is completely normal. One starts counting from 0 and the other from 1. Basically, the drive is one but the channel is zero. Yes, it's confusing.
Even if the sync has nothing to do with it, you really don't want to start trying anything while it's ongoing. But maybe somebody has some suggestions for afterward. Are you comfortable with SSH and the Linux command line? Anything you do is almost certainly going to have to be done from there.
This behaviour seems to have survived a power cycle and also a factory reset. I don't remember it being any other way.
Like I said, the other suspicious thing is that the front panel on the box lists the drives as "Disk0", "Disk1", "Disk-3", "Disk-2", "Disk-1". I would guess the ui is looping over them from 1 to num disks or something, and missing ones less than zero? Does the physical location in the box have anything to do with it? I inserted them from the bottom bay upward.
I'm more than comfortable using ssh and linux, my technical linux knowledge is not massive though.
