316 Expansion - New HDD status "unknown". How do I bring it online?
Expanding 316 from 4TB drives to 6TB. Install of first 5 disks no issue. 6th disk added before resync finished after 5th disk. 6th disk shows as "black" on admin page. (Systems > Volumes). How do...
By adding larger drives, you added a "layer" to the volume, which is a separate RAID. When you jumped the gun, the first RAID sync (6 x 4TB) was apparently complete (thankfully, or you would likely have killed the whole volume). The second layer (5x2TB at this time) is still syncing. The system will not add another drive till that sync is complete, so it shows as black.
Both RAID layers of your NAS are degraded. The original one of 4TB partitions is degraded because drive 6 is missing from it. The second layer of 2TB partitions is in re-sync. If anything goes wrong, you will lose the volume, so do nothing until sync is complete.
Hopefully, after the current sync completes, XRAID will figure things out and add the remaining drive. But you have put it in a condition it may not be expecting, so we can only wait and see. If the last drive does ultimately get added back, it will also need two syncs -- one for each layer.
You can see if cat /proc/mdstat from SSH or mdstat.log from the log ZIP file show the original RAID (most likely md127) is "pending" re-sync. If it is, that's a good sign. The other (likely md126) will show as in progress. md0 and md1 are the system and swap partitions, you can ignore them for now.
If it does not automatically add both layers of the last drive, try removing and re-insertiong drive 6 when all syncs are complete. And if that doesn't do it, reboot the system. If both of those fail, I can probably give you SSH commands that will do so. But you'll want a current backup before you do it (which you should have done before replacing the drives, anyway) just in case things go wrong.
BTW, unless you suddenly need a huge boost in space or got an incredible deal on the drives, replacing all drives at the same time was not your best move. They will now all be the same age and may fail at nearly the same time. Replacing two now would have added 2TB (or more, had you used even larger drives), and each one after that would add another 2TB. But, it's too late to change that now.
Hi Stephen. Happy New Year!
The data is all accessible. It's just that the 6th disk doesn't show as "active" nor does the amount of useable space seem available. Eveyrthing seems fine it's just that the 6th disk is "black" on System > Volumes. I tried formatting that drive from the admin page which worked before on other drives. After that they showed as available (blue). Not sure what's going on nor how to explain it properly.
System is resyncing with 5 drives. Log shows drive added to Channel 6 of the head unit and nothing else. Disk state (hovering over the drives) say all are "online" except the 6th which says "unknown".
I'd hate to do a factory reset. Nowhere can I find how to bring that drive to an "online" status. Selecting that drive gives me the X-Raid, Format and Global Spare as selectable options.
Dave-
Edit: Volume is resyncing therefore degraded.
By adding larger drives, you added a "layer" to the volume, which is a separate RAID.

Thanks, Stephen. I appreciate your time and expertise.
This resync will be done in about 2 hours so I'll fine out then. Wasn't thinking when I replaced all the drives. I should have stopped after 2 or 3. I did get a good deal. WD Red Pros 7200 rpm for less that the standard WD Red 5400s. Amazon, where else?
I am backed up so that's not an issue. Worst case I'll have to do a factory reset and restore my data.
I'll let you know where things stand in a few hours.
Dave-
All seems well. After the resync of 5 disks the unit did recognize the 6th disk and is now doing a "final" resync of all 6 disks.
Thanks once again.
