Hi, I am having the same problem. Unistalled 2.5.4, installed 2.6.9, after upgrading to El Capitan. Disconnected and reconnected the Drobo, but the Dashboard will not detect it.
Hi, unfortunately I was not aware of the issue and did the upgrade with the volume mounted.
I have five drives on the drive. Later I can give you the sizes (I’m not in front of this minute).
All the lights are green.
I will try the USB idea when I get back.
Beside testing with USB connection. You can try the following as to manually force mount the Drobo Volume. Once Drobo Volume mounted… verify that you can access the data in that Volume thru’ OSX Finder. Then do a restart of the Mac and see it the Drobo Volume auto-mount after that.
Steps:
**Lets try this on Thunderbolt connection.
With Drobo 5D connected to Mac (El Capitan) using Thunderbolt.
Confirm that Drobo Volume is NOT mounted.
Now open Disk Utility … note that El Capitan has a all NEW Disk Utility interface. Looks very different from the old Disk Utility.
On the LEFT panel of the Disk Utility, you should see a “External” section.
It should show the Drobo 5D device and under it the Drobo Volume (Partition).
Click and Select the Drobo Volume under the Drobo 5D Device… (The Drobo Volume entry maybe grey out but is ok)
Now take a look at the Right Panel of the Disk Utility.
You should see a Table with a Row field called “Mount Point” and it should say “Not Mounted”
Now move the mouse to the very Top of the Disk Utility… do you see an icon label “Mount”.
Click on that and manually mount the selected Drobo Volume.
Check the Disk Utility successfully mount it, and “Mount Point” is no longer showing “Not Mounted”. Is should be something like /Volumes/xxxx etc
Go to OSX Desktop… or Finder… can you see the mounted Drobo Volume?? Access the data?? all good?
Reboot the Mac and check if Drobo 5D Volume gets mounted on boot.
**Note: If Disk Utility does not list out any Drobo 5D Device as external storage… be it on Thunderbolt or USB… That is OSX El Capitan is not detecting there is a Thunderbolt or USB connection at all.
Good news.
I have tried the USB test and it did work. The Drobo mounted and the Dashboard was able to recognize it. It then prompted me to upgrade the firmware, which I did. It is now up and running, mounted on the finder, but still connected via USB. I ran out of time, so I will test mounting it via Thunderbolt tonight. But at least I know it works via USB.
That’s good news! At least now you are able to mount the Drobo using USB and have access to the data which I think is important to have access to it.
As for the issue on TB port. My thinking is that maybe El Capitan changes something with the Thunderbolt driver etc… and causes Drobo not mounting or not recognise by the OSX El Capitan.
I have a Drobo 5D that was working fine until I updated to El Capitan; I also have a Drobo 4 bay which intermittently connects.
I have read all solutions including Reinstalling newest version of Dashboard,resetting the PRAM/NVRAM and tried them to no avail. The drive does not show up in Disk Utility. I am connected using USB 3.0 and have already tried to connect via regular usb to no avail. Is there anyway to force load or discover this drive? I have switched cables etc however all of these attempts are fruitless… Getting desperate.
BTW all boot and status lights are proper on both drives.
to remove the drives from drobo (remembering the order)
to power up just the drobo empty
after it boots up, to then power up the mac
does dashboard recognise the emtpy drobo?
if you can then power all down again
and to then while power is still all Off, to put the drives back into drobo as they were
and to then boot up just the drobo (letting it go through the boot up sequence)
and to then power up the mac and see if it improves things?
