I have a Drobo 5N with the latest firmware 3.5.11 [8.90.81921]
It used to have 3x3TB and 2x4TB installed. In May I replaced two of the 3TB drives with a pair of 6TB, and left a 3TB and two 4TB drives in it (so now 2x6TB, 2x4TB, 1x3TB). I first backed it up to a QNAP NAS with 4x6TB drives, so I would not lose data. At that time I installed the new firmware that would support 64TB and wiped/reset the Drobo back to default factory settings, and then restored all my data from the QNAP after re-creating all my shares.
Everything was fine until tonight, 4 months later, when I get an email alert that “Data protection is in progress.” I check the drobo dashboard and one of the new 6TB drives in Bay 0 is “missing”. I go down to the basement and look at the drobo, and bay 0 is solid yellow, and bay 1-4 are blinking green/yellow. I double check the drive in bay 0 and it seems to be tightly inserted, therefore it’s dead and the drobo just doesn’t see it anymore.
While it was working on Data protection, I wanted to remove the bad drive and insert a new one, but the second error message said “do not remove any drives”. So, I waited a couple of hours and when it was done, the drive in Bay 0 LED is now red, and the others are green, as I type this.
I have 11% free space with just the 4 drives working. I know I’m ready now to install my backup 6TB drive that I wisely bought a while back.
(1) Could I have installed the 6TB drive in Bay 0 while it was doing Data Protection In Progress? Need to know for next time.
(2) Why does the Drobo now say “Drobo cannot protect your data against hard drive failures until you provide at least 2 hard drives for single, or 3 hard drives for dual disk redundancy. Insert a new hard drive into the empty drive bay indicated by the red light.”
Shouldn’t I only need to insert one, not two drives?
(3) As I was typing this post, it keeps switching between the message in #2 above, and then trying data protection for a 30-60 seconds, and then back to message #2, and I get emailed EVERY TIME! Why does it do this if I haven’t inserted the drive yet. I want to insert a 6TB disk now, but not if it switches to data protection in progress while I’m doing it, if that could cause data lose.
What do I do?
