I was wondering if anyone else has experienced the Drobo FS just disconnecting and not being able to be mounted again without a manual reset. This happens randomly to me in the middle of transfers that are pretty large. Usually 100 or more files about 1 - 2 GB. I am on a Mac.
I have been working with support for months now, and am starting to feel like there is no solution to my problem. The Drobo is still visible through Finder, but I am unable to mount it again. I quit using drobo dashboard, and started using AFP to mount it. To do the transfer I have been using rsync, instead of drag and drop through Finder.
This is the output I get when it fails:
rsync: writefd_unbuffered failed to write 32768 bytes [sender]: Broken pipe (32)
rsync: write failed on "/Volumes/Media/Movies/the_wicker_man.mp4": Invalid argument (22)
rsync: rename "/Volumes/Media/Movies/.the_wicker_man.mp4.BqyB7C" -> "the_wicker_man.mp4": Read-only file system (30)
rsync error: error in file IO (code 11) at /SourceCache/rsync/rsync-40/rsync/receiver.c(268) [receiver=2.6.9]

rsync error: error in rsync protocol data stream (code 12) at /SourceCache/rsync/rsync-40/rsync/io.c(452) [sender=2.6.9]
Any help or ideas for troubleshooting would be greatly appreciated
Hi just bought a brand new Drobo-FS and I am having the same problem.
I am using Windows 7 with mine.
I am in the process of copying 4 TB of data from my old first gen Drobo to my Drobo-FS and after about 8 hours of copying, the Drobo disconnects from the network and I can’t see it using the dashboard anymore.
I have to manually restart it to get it to come back up.
This has happened to me 3 times now and I have only been using my brand new Drobo-FS for 3 days.
Very frustrating.
It shipped with the latest firmware and dashboard. And my network is not the problem because I have 8 systems connected to it and they never lost connection to each other.
No. In fact I am on transfer #4 now (6 hours into it). Usually during the 8th hour it will disconnect from the network.
When it disconnects, I can not access it with the dashboard, from my main Windows 7 machine, from another of my other Windows 7 machines (4 of them), or from two of my Macs (all hardwired to the switch that the Drobo-FS is wired to).
One of the times that Drobo disconnected, I manually restarted it, and it still would not mount (all the lights on the front were fine and green and I could hear the drives indexing).
I had to turn off the unit from the back, and unplug the power cord for 60 seconds, plug it back in and then it finally mounted.
I was having way less trouble with my first generation Drobo and now I am beginning to question why I upgraded in the first place.
The only way to make this the least bit bearable was to use rsync to make my transfers, so I didn’t have to worry about redoing the transfer or losing data when it disconnected. I also installed the ssh drobo app and tried to watch top while making the transfer. It seemed at certain points the transfer speed would drop or completely stop and the system load would shoot way up. I’m wondering if when this happens, maybe some process is completely failing that normally is responsible for keeping the drobo on the network.
I had the same issue as you where I still could not connect after a hard restart, and had to try restarting multiple times for the drobo to connect again.
I have had a support ticket open for months without resolution at this point. I have even received a replacement drobo, and it didn’t behave any differently.
Thanks for your input. Keep me posted if you find anything out and I will do the same.
I was shocked to find your thread dated Oct 21st with no replies especially since I had the problem on the very first large data transfer that I did.

I have not tried that but I have so many systems here on my network (PC’s and Mac’s) that I doubt that is going to make any difference. I have been using my router for years (a very expensive Dell model) and I have not had any trouble.
I did try a different cable and port on the router and I rebooted the router but that made no difference. As soon as I start a large file transfer, 8 or so hours into it the Drobo-FS will disconnect itself from the network and it will not rejoin until I power cycle it.
I am not going to disconnect my PC from my network to beta test the Drobo-FS (by connecting it directory to my NIC). I shouldn’t have to do that. If the problem happened in the first 15 minutes I would be more willing to do it. But it takes 8 hours or longer to happen and I can’t be off my network for that long period of time.
Sounds similar to a problem I had in the past with a third-party software firewall. Things were fine with small file transfers, but when I tried to send a ~50 GB video file over. It’d go, go, go, then STOP.
On the server, it said the traffic from my machine was being blocked because it was a suspected DoS attack.
Does your router do any security screening? If it has a log or syslog, check to see if it’s detecting a broadcast storm or attack of some kind and auto-blocking the FS or killing the port.
My router/switch does not do any security screening. I can copy huge amounts of data to my other computers on the network and they never get blocked / timeout / or disconnect.
I have a Drobo-FS with 5 hd’s - a mix of WD and seagate.
I have had similar copy fails when doing large files over wireless, which i blame on the wireless, however, I have had no issues copying from a hard-wired lan connected computer.
Also, have copied 1TB of files over the past week - (it did take awhile) using Drobocopy with no errors and the email report worked as well.
I am using a gigabit backbone as my network , but this would only increase copying speed and not affect copy failure.
The last straw was trying to copy my 200 gig picture file (a truecrypt volume) over to the Drobo FS and having the Drobo FS disconnect from the network 3/4 of the way through the transfer.
I tried it 4 different times; same result every time. The Drobo FS will disconnect from the network and I can only get it to rejoin after I power cycle it. Very frustrating.
I found a very competitive replacement that I hope will do the job.
I am very disappointed in the Drobo FS. After being on the market for 7 months and up to v1.05 of the firmware, it should not have these problems.
If anyone cares to know what I am getting to replace it, please PM me. I don’t think these forums is the ideal place to discuss a competitor’s product.
Weird. It’ll be interesting to know whether you have success or not with this other brand in transferring large file clusters. When I set up my Drobo FS for the first time my first task was to copy over 450GB of FLAC music files. It completed the transfer within a few hours without any problems.
I really wish I had your luck with the FS. I am such a Drobo fan having owned one since early 2008. But I have talked to numerous people now with the same problem as myself so I know this is not an isolated problem.
Same problem here…About 100GB into a 180GB transfer it dropped the transfer and dashboard lost the connection. I could ping the device over the network though.
