Droboshare is not directly supported by drobo utils running on a linux host. However, the droboshare itself is a linux host, and it is possible to run drobo-utils un-modified on the droboshare itself. A python interpreter is needed to run drobo-utils. A python interpreter has, itself, a number of dependencies. So you number of packages need to be installed on the droboshare. This is where DARFS comes in.
The Droboshare Augmented Root File System (darfs) is a 60 MB or so download you can get from drobo-utils.sf.net. There isn't any source code, because, well, nothing from any of the packages has been modified. there are instructions on how to build DARFS in DEVELOPERS_
DARFS is a standard droboshare root file system, with some packages added: openssl, openssh, berkeleydb, bzip2, a fairly complete Python 2.6.2. drobo- utils is a python app. and it works in line and API mode, natively, on the droboshare. for example, I've used it to replace the firmware. no problem at all.
People un-afraid of the command line can upgrade drobo firmware, query status, and take diagnositc dumps, from the command line on the droboshare itself, just as they would on any linux host computer. But a full GUI would be too much for the little processor and more importantly the limited memory in the droboshare, so that is not provided.
Download it from drobo-utils.sf.net: steps:
- copy the tar file onto somewhere on your share.
- log in via DropBear ssh as a root user on the droboshare.
- cd /mnt/DroboShares/YourDrobo (root of drobo file system, for example)
- tar -xzf darfs.tgz (root of drobo file system, for example)
- the root directory of the tar is 'slash'.. it will be under YourDrobo
- export PATH="/mnt/DroboShares/YourDrobo/slash/usr/bin:${PATH}" (which is where python and drobom are.)
- drobom status
you're done!
all you need to do is:
ln -s /usr/libexec /mnt/Droboshares/YourDrobo/slash/usr/libexec
Try an sftp from another machine (as root...) and it ought to work.
(explanation: when one tries to sftp to a droboshare, it gives an error about trying to exec '/usr/libexec/sftp-server'. Openssh builds the right binary, but Dropbear doesn't know where to look for it. the libexec directory isn't there on the droboshare, so there is no harm in creating it and linking into DARFS.)
With DARFS, and the third party software you can get from drobospace and drobo.com, the droboshare is very open and hackable. However, there remains a one limitation: There is no open source way to upgrade or modify droboshare firmware. If you want to re-flash to a factory original state, you need the vendor dashboard.
DARFS was build in late 2008 as a technology demonstration. There was not much interest at the time, so it has not been followed up since that time. If there is sufficient interest, may take it up again. The quality of the build documentation procedure is, well, poor. It would have been necessary to perform the entire procedure from scratch to verify the details. The information here is basically notes to the author. YMMV.
I used this procedure on ubuntu jaunty, but the same packages ought to work identically on Debian Lenny. the idea here is to use the fabulous scratchbox2 tools developed [1] for use with the Nokia Maemo.

Cross compiling is usually a PITA (excuse me.) you want to use a nice fast, powerful desktop machine (the "host") to compile something that will run on a much less muscular embedded systems (the "target") Scratchbox 2 looks at a binary, and if it is for the target cpu to run, then it invokes the qemu processor emulator so that it will run on the host platform under emulation. When the binary found is a host binary, it just runs it normally. This makes cross-compilation very transparent. The other magick that it does is to invoke the cross-compiler when the package's normal build procedure will try to invoke a native compiler. Scratchbox removes a great deal of pain from cross-compiling.
So the steps that follow will allow you to build an environment where it is easy to build additional software as desired. It is worth noting that the droboshare has a cpu that is relatively powerful, and relatively idle in most cases. It is only prevented from being really useful by the limite memory available.
You need a droboshare, with a drobo on it. You need also need to download some stuff:
mkdir ~/drobo cd ~/drobo mkdir droboshare cd droboshare mkdir Downloads cd Downloads Drobo SDK: http://www.drobospace.com/download/11742/Data-Robotics-SDK/ You need to get root access via Drobbear, read the SDK documentation for that. # which ought to get you ... SDK.zip cd .. mkdir sdk cd sdk unzip ../SDK.zip
You also need (as per the SDK) a code sourcery toolchain: http://www.codesourcery.com/sgpp/lite/arm/releases/2006q1-6 with target platform: ARM Gnu/Linux

The idea here is to get a starting point by making a copy of the root file system from a droboshare. After downloading the the SDK from drobospace.com, and enabling root shell access, just log into the droboshare and:
trestler:/etc/apt# ssh root@droboshare
