Hi, My first post here. I have been using my Drobo 1st generation with 4x1TB drives for a couple years now as storage for my iTunes library. It is now 85% full so I bought another Drobo 2nd generation to daisychain together for increased storage. My understanding from reading here is that this can be done, but must be done properly or all data can be lost. Don’t want to do that! I hope members of this forum can confirm my plan or get me headed in the right direction.
First, as I understand it, I must transfer all data on the Drobo 1st gen. to a separate temp HD. I understand from some posts here that can take a day or more? If I understand correctly I should double click/open the Drobo icon on the desk top and drag the files to the new temp storage. Correct? Is there a different / preferred way to transfer the data? Should I select all and drag to the temp storage or do it incrementally?
Then I must reformat both Drobos to 16 TB for max flexibility and expandability. Both Drobos would be formatted to the same storage capacity and use the same firmware and dashboard version… but I don’t know if that is an absolute necessity? I don’t understand if this should be done with the drives in place and the units linked together?? Or if I connect the Drobos separately? Without drives? Does each Drobo have a different name?
Since the Drobo Gen 1 only has 1 USB connection, it would be connected to the Drobo 2nd Gen via USB, and then from the Drobo 2nd Gen. to the computer via the Firewire 800 connection. Is this correct? Will it show on the desktop as a single Drobo or as two separate drives/volumes (… not sure of terminology here)? I want to connect it directly to the computer, rather than via DroboShare, to maintain the fastest, most reliable connection possible. Also I’m not sure if the data shows up as being on two separate drives/volumes will iTunes be able to access the whole library or will it get confused and not know where to look for the “tunes”? Will I wind up having two iTunes libraries? I’m hoping someone here will have some experience with this.
I guess the next step is to reload the external data back onto the connected /daisychained Drobos. Again I assume it will be a drag and drop operation from the external temp storage to the Drobo icon/s? Where I assume it will be spread evenly between the two Drobos. If the Drobos show as separate drives/volumes on the desktop is there a protocol on naming them? Should I drag and drop the data to the first Drobo in the chain or does it matter? If this operation needs to be stopped or delayed for any reason is there a protocol for doing that with our loosing data?
My computer is a iMac (7,1) with 3 USB ports, 1 FW 400 port, 1 FW 800 port, and an ethernet port. The FW 400 port is used to connect directly to the DAC. The FW 800 port would connect to the Drobo 2nd Gen. and via USB to the Drobo 1st Gen. Will this setup work? I am not sure if the FW 400 and FW 800 share the same buss. Will that be a problem?
I’m very paranoid about doing this because I don’t want to loose data and see 2 1/2 years go up in smoke. Any comments, suggestions, or personal experience will be welcome. Thanks, Rod
