I have a 5D which had 5 x 10TB Drives in it.
I am migrating all of my data across to a Drobo 8D using Carbon Copy Cloner.
Once a large portion is completed copying, I delete the original content off the 5D, which creates space.
Once I had enough overhead, I removed one of the 10TB drives from the 5D and put it in the 8D.
The 5D went into data recovery mode, and eventually showed the now empty bay as critical, indicating I needed to put a drive in.
I put a 4TB drive in, and after data recovery mode, the bay still shows as critical.
I tried removing the 4TB again, hoping it would prompt some sort of re-calibration, but with the bay now empty, it still shows it as critical.
The unit has 40TB of Drives in it, for an effective usable total of 27.13TB and only 12.31TB of that is in use.
From what I understand, I should be seeing all green lights as there is enough available space in single disk redundancy mode?
I have tried Shutdowns, re-starts, removing and re-installing the disk packs, booting the drive with no disks etc.
Any info would be much appreciated!!!
