I recently had a Drobo FS - five discs "beyond raid" NAS for ten months.
It stopped working. Would not start. Lights were on, but nobody home. Disks can not be transferred to another chassis I am told. This is truly "beyond raid".
You have NO way to troubleshoot a DROBO FS if you can`t acccess it over the network. No other ports to connect to, only the network contact.
The logs are encrypted and can only be read by Data Robotics anyway, so no big loss there.
The seller Dustinhome.no returned it to me after two weeks with the message that I will have to send it to Drobo in the US, hence omitting their obligation to fix it. They told me that Data Robotics demand that all service on their devices are handled by them.
So - it is now in the trash. I took a picture of it as I applied a large hammer on it. At least a guy has to have SOME fun. I had no backup - stupid me, so 3,8 Tera of data is lost.
A Qnap 859 pro+ has replaced the Drobo, at least that can be repaired, or discs moved to another unit. The discs were fine and dandy by the way.
Looking forward to ripping all my DVDs and BDs again
I have backup now as well
