Sorry if I’ve missed this somewhere - it seems like something which should be documented somewhere but I didn’t find it yet.
I arrived a few mornings ago to find my Windows workstation rebooted, my USB Drobo disconnected, and the Drobo showing a red light on bay 1. I assumed the drive was dead but now know that the light means:
Solid Red: Add a drive or replace the current drive with a larger drive immediately. Drobo is critically low on space.
To find out what the Dashboard reported I had to power cycle the Drobo. The Dashboard reported “data at risk” with “data protection” in progress, which it completed last night. Now all appears well.
So what happened? Did one volume fill and force the array to rebuild? This seems rather counter-intuitive since I have 1.67TB reported free in a 2.72TB array. Is this likely to happen again - important since it took over 9 hours to rebuild? Is this a “normal” occurrence?
I doubt that I should I be following the instructions to replace the drive with a larger volume (I have lots of space and the Drobo reports all is well now) - correct?
