Hello. I purchased my B800i in 2012 so that makes me a POS to Drobo tech support.
I have about 20TB of total storage with 2 16TB partitions. Everything was fine until the other day when the first 16TB got full. Within Drobo dashboard the 2nd volume appeared to be mounted but the status says not available. I unmounted the drive, and tried to remount and the loading wheel next to the partition has been spinning for hours. This happens every time.
Any help would be appreciated. I was going to upgrade to the B1200 but Drobos lack of support, which I knew of before even purchasing my Drobo has been made even more clear that I should seek alternative future proof options.
