I've done a little bit more research. It seems that the source of error is definitely the Drobo/Time Machine combination, Time Machine can't handle that there is no real volume size limit of Drobo if you don't partition it. I have not configured a partition for Time-Machine, which was no problem with SL Server. Did you? I don' t want to loose the volume flexibitility of Drobo.
After the problem with Drobo occurs I have to restart Drobo for beeing functional again. When I stop Time Machine and Time Machine Server Drobo seems to work flawlessly. The next thing I want to find out is if the problem source is Time Machine in general or only the Time Machine Server functionality.
This isn't just a Lion Server issue, but, something to do with the Drobo firmware and Dashboard itself. I also am having this issue and have a trouble ticket open with Drobo to fix it. Sent them kernel logs, system logs and a Diag report from the drobo today.
At the moment, the only way I could continue to use my DroboFS was to remove any trace of the kext and LaunchAgent/LaunchDaemon (whichever, I can't recall) that is installed by the Drobo Dashboard.
For what it's worth, I *was* able to mount my DroboFS by using SMB, but, AFP is crashtastic on the Mac that mounts it and Time Machine is definitely non-functional.
First, the FS and the "standard drobo" are having issues howerver they are seprate.. the FS needs to have the firmware updated. Once you do this the time machine shoudl start working again.. and I have had no other issues..
The direct attached storage is freezeing regularly and the only way I have found to recover is to force a shut down of my mac.. DataRobotics has recognized that their is a problem howerver they are pointing at Lion and saying that they are having issues with many external storage devices. They did suggest I try the USB vs the firewire port.. I tried that and it did not recognize after failing from the Firware. I plan on tryong to get up the USB tomarrow from the start and see if I loose connectivity. As of 7.28.11 i am on the latest dashboard and firmware release. I am also on the 2nd gen Drobo.
I hope a patch comes quick or I will have to downgrade..
I have the exact same problem, but with a DroboPro connected via iSCSI. I found that uninstalling Dashboard and going back to a very early version (1.7.3 in my case) does help a lot, but does not entirely fix the problem. With Dashboard 2.0.x the Drobo unit is basically unusable with constant disconnects/freezes. With Dahsboard 1.7.3 this only happens once every couple of days.
I have had a support ticket open with DataRobotics for more than a months now, but they are unable to fix it.
I am also having issues with Time Machine and a Drobo 2 attached to a Mac Mini running Lion (non server atm) via Firewire 800. I have tried a couple of different cables. It's occuring when I am doing a Time Machine over the network, will get 30-40GB in then will just freeze.
For the moment I am taking the Mini back to Snow Leopard until I see some more information on this topic.
Well, I'm glad at least I'm not the only one having this issue. Initially I thought my machine wasn't happy with Lion, but then noticed it was only applications accessing my Drobo that were freezing and/or erroring (Time Machine, iTunes, Finder, EyeTV and iFlicks exporting to iTunes, ...). I then wondered if it was because I had recently upgraded one of the drives, but I had done that before installing Lion, and it had re-distributed the data and was working fine in Snow Leopard.
I have a Drobo 2 connected via FireWire.
I've also opened a support ticket, the initial reply was that updating Drobo Dashboard from 1.7.3 to the latest 2.x version should fix the issue. It didn't (if anything it made it worse).
As well as freezing constatly, I also find that my Drobo isn't coming out of standby when I boot, or restart, my machine, and I have to power-cycle it to get it to come to life.
I've unmounted the drive, so I can use my iMac, but it means I've not got Time Machine running at the moment, and have no access to my iTunes Media.
I hope this is sorted soon, as a home user it's frustrating, I can only imagine the issues it must be causing for people using Drobo's in their businesses.
(I'm just on vanilla Lion, not server)
Possible good news!! Try to turn everything off.. change to the USB port and see how it goes.. I switched to USB and no lock ups in 24 hours.. ( I am copying a bunch of files) With Firewire it was running a few hours then locking up..
I hope to see some confirmation that this works from other posts..
I agree that we should keep the Drobo (USB + Firewire) and the Drobo FS as sparate issues. No I did not partition my Drobo. It's being used as one volume.
I've had a couple of rounds of messages with Drobo support and below is the latest set of instructions. After following them I can reboot without issue and browse the Drobo volume. I remains TBD whether or not I'll get another freeze in the next 24-48 hours.
