[quote=“fraban, post:6, topic:140873”] Ok my drobo is out of warranty and still it´s a brick - can you give us some advice how your “trick” is working. Van you give us some more details ? Is anybody here who was able to get a DROBO FS fixed.
While hoping David will reply, I passed his post along to some IT buddies.
[quote]My guess is that a “3.3v TTL USB breakout board” is a device that lets you plug a USB cable into one end and attaches to the motherboard of your Drobo on the other (in a non-USB looking place that actually is USB but shaped wrong and at the wrong voltage). Then you plug the USB cable into your computer and it would present the Drobo’s operating system volume (not your data) as a USB drive.
The poster says that “Drobo only gives 2mb for the log file” which likely means that there is a log partition which is 2MB in size and that it is full with this file. This kind of thing is common on embedded linux devices but not so much for other platforms. So the likely gotcha is that if you plug this into a Mac or PC that it won’t be able to read the partition and you’ll have to plug it into a Linux machine to be able to access the data.
If you were able to do that then you could delete this log file and that would fix the problem. Computers often will decide to do nothing rather than do something they can’t log. If the log file really did fill up its meager 2MB partition that could very well be the reason that your Drobo isn’t booting. Of course it could be a lot of other reasons…[/quote]
[quote]Usb breakout board is how to add usb to hardware that doesn’t have it, usually for hacking firmware on embedded systems.
Log file limits can certainly brick tiny Linux builds. Interesting. Not sure if it’s worth the trouble.[/quote]
finally, a link to a relevant discussion here in the forums.
I’m asking for help in that thread, which is chock full of technical details.
