My Drobo Gen2 decided to lose 6TB worth of data tonight.
it’s loaded w/ 4x3TB drives. Formatted as a single HFS+ Journaled 16TB volume on a Mac Mini running 10.9.5. For a while now I’ve needed to upgrade two of my 3TB drives to 4TB and get some extra space. I’ve had one red light for almost a year, but I haven’t added anything else to the drive, so it hasn’t been an issue. Tonight I was using the files, copying some things from the file system, and then I went back later and everything was missing. All told, 6TB worth of data is no longer showing up on the Drobo. After a bit of a panic attack and a reboot I go into Drobo Dashboard. The drobo takes a good 5 minutes to populate in dashboard. Under the Capacity pie chart, it shows all 7.78TB of data. However, my red light is gone, shows green across the board. But, if I go into the Volumes tab, it shows only 1.7TB used.
I’m currently running disk utility on the drobo and it is sitting on “Checking catalog file” and has been for about 40 minutes. We’ll see what it looks like in the morning, but anything else to check would be great. Thanks.
