One of my Drobos had 4x1.5tb drives and to expand space, I am replacing two of them with 2tb drives. I pulled the top drive out and replaced it with one of the 2tb drives. Drobo took 72hrs to complete the rebuild (the “data protection”).
When it completed, it appeared to reboot itself. When it appeared on the Dashboard again, the “Data Protection” progress bar was just a full spinning barber-poll, all the drives in the “Drobo Status” box were flashing yellow, and it says “Data At Risk”.
It has been almost three hours, now. None of this has changed. What exactly is it doing, since it already said the 72hr rebuild was done and it had restarted? How long is this next phase likely to last? It still gives no indication of time and the progress bar is just full and spinning.
Is this even expected behavior or has something gone horribly wrong?
Update: Also, while I’m able to access the file structure, I’m not able to actually access the contents. For example, I can’t play a video that is on the device. Nor can I copy a file from it. The drive has also disappeared from the Dashboard for the second time since the whole “restart” after the completion of the rebuild. Also, it has rebooted itself two more times. Each time, going back into the same mode as described above. All blinking lights while dashboard says “in progress” with no actual ETA.
Update: No longer appears as a mounted drive (not that it matters, since it wouldn’t let me access data on it, anyway).
Update: I have also followed the steps discussed in this thread about completely resetting it: http://www.drobospace.com/forums/showthread.php?tid=1782&page=1
Now, it is back to blinking orange and green with the spinning progress bar that just says “in progress”. It does not indicate any ETA and while it claims “you may continue accessing your data”, the drive doesn’t even appear as mounted and it no longer has the volume name (instead, it just shows as "Drobo in the dashboard).
Update: Now the drobo has vanished from the dashboard, which says no drobo is detected. Meanwhile, the drobo continues to flash green and red/orange. I presume I shouldn’t screw with it at this point, so even though it isn’t detected by Dashboard, I’m going to leave it running with the blinking lights and assume something is getting down.
