I have a Gen 2 Drobo which I’m having huge issues with. The issues are of different kinds, and pretty hard to describe in a good way. But I’ll try anyway.
I have not opened a support case yet, mainly because I don’t really know how to describe the issues. So I’ll try here and we’ll see what You guys say.
The Drobo is connected via USB to a modern high-performance PC running 32bit Vista. Drobo firmware and dashboard are upgradet to the latest versions. Vista and all the drivers are updated as well. The PC have a very solid and stable setup, with 9.9 stability points (Performance and Stability, Administrative tools).
Drobo running 3x1.5 TB + 1 TB. The volume is set up to 16TB. It’s over 90% full right now.
Issue #1: Boot time
Taken that my PC does recognize the Drobo at boot time, the boot takes hours, literally. I haven’t clocked it, but I’d say ~2 hours. Drobo mounts just fine after boot is complete. Is this boot time normal?
Issue #2: Drobo not recognized
Most of the times i boot my computer, the drobo is not recognized at boot time. When this happens, it does not mount after boot is complete (boot takes under a minute in this case). Rebooting the drobo sometime helps, letting Vista recognize the drobo and mounting it. But often I just get the “A USB device failed to”-message. Most of the times, the only way to solve this is to shut down the PC, reboot the drobo, and turn on the PC when the drobo is in the boot state.
Issue #3: Drobo fails when rebooting.
My Drobo constantly get’s in the “continuous reboot”-state, flashing red and blue lights and then spinning the drives down. I have found a workaround that actually works basicly every time: Turn off the drobo. Pop a drive but let it stay in the casing. Turn on the drobo, and reseat the drive when the status lights start to move from left to right. The drobo then boots as it should, and there’s no relayout. The method described in the KB sometimes work, but mostly not.
This issue have increased heavilly as I’ve filled my Drobo with data. I never had this issue six months ago.
The really strange thing is that all these issues seems complete random! I can reboot my computer several times, with the drobo being recognized and the boot time only 15-20 minutes or so. And then randomly, the drobo enters the continuous reboot state. Even after dealing with the continuous reboot issue, the Drobo wont mount. Even after power cycling both the drobo and PC, the problem persists. Then, out of nowhere, the PC boots up fine, the drobo mounts, and everything is working ok. For a while…
It has happened that the drobo entered the continuous reboot state out of the blue while the computer is up and running and everything is ok, but normally it only happens during reboot (I tend to try to not reboot/shut down my computer, but sometimes it’s unavoidable, and my drobo gives me a headache almost every time
I’ve had very similiar issues with the drobo hooed to a Dell XPS M1330 laptop.
So, what do you think? Is there a possible technical issue? Should I create one support ticket for all of my issues (since they probably are related), or should I create one for each kind of issue? Should I try to have my Drobo replaced? (It’s still less than a year since I bought it).
I’m really thankful for all replies!
