My Drobo S (second gen) started being very slow yesterday, to the point that copying files to it using the Mac’s Finder and iTunes could not complete.
The latest Time Machines backup took over 2 hours for 6GB (to an identical Drobo S by the way), which is under 1MB/s.
However, all LEDs were green.
I power cycled it a few times, ensured that Drobo dashboard and firmware were up-to-date.
I suspect there is something wrong on the hardware side but I have no way to find out which disk is the culprit.
Trying to get an indication of that, I removed one drive for one second then put it back on.
NowThe Drobo S, after power cycling, now reports it is protecting data …and needs 335 hours for that (and going up!)
I am fed up with these Drobo drives and have ordered 2 4TB drives which I plan to use concatenated or with RAID 0 in FW enclosures (my Mac mini does not have USB 3 or Thunderbolt but is heavily modified for sound quality, so I will keep it even if its inputs and outputs are slow)
This is a risky setup but I still have a working Drobo with Time Machine backups, and it can’t be worse than my current Drobo setup.
Any help greatly appreciated.
Thanks in advance and have a great day.
