I’ve been setting up my DroboFS this past week, and now that I’ve gotten beyond freezes at startup, dying drives, I/O contention, and the sheer pain of copying 2TB over the network, I have two lingering issues - wondering if these are common or not.
Periodically the DroboFS will stall during I/O. For instance, during a large file copy it will be zipping along, then the activity light will turn solid green (or go off) for up to about 30 seconds, during which no data is transferred. After this passes everything returns to normal for a few minutes, then does this again. Graphing my throughput looks like a wide platueau with deep canyons.
Not sure if it’s related, but it seems to take a year and a half for the Drobo to list the shares available after connecting and authenticating - and this is with the drives already spun up. It can sit for 30 seconds to a minute before I can get the list of shares; once I choose one it’s fine - stalling above notwithstanding.
Are these known issues? I wish there was some way to isolate if it’s an issue with the FS or maybe some strange interaction with the drives I have installed; i.e., which do I replace to fix this - the FS or the drives?
I spoke with support today, and confirmed something is amiss with the Drobo FS. I had bought a second one (long, silly story), and that one performs flawlessly with the same network, disks, setup, etc.
Afraid so, it had to be replaced. If you can’t be without your data (something I definitely understand!) then see if you can get advanced shipment of the new FS. Once it arrives, it’s as simple as updating firmware (always update firmware first), then popping all the drives out of one Drobo and into the other.
