My Drobo 5N is fully populated with 4TB mechanisms (20 TB total), and only two blue capacity lights are illuminated.
There are 6 Shares dedicated as TimeMachine backup partitions.
Some of my users are experiencing TimeMachine backup errors:
[color=#FF0000]The backup disk “Drobo 5N” is full[/color]
This cannot possibly be true.
Is there a way to expand or reallocate the share size partitions? It appears I configured the device wrong, and it is reporting full when only 20% of the available capacity is being utilized.
Also, why isn’t TimeMachine simply deleting older backups?
One theory I have is that the users impacted are running Parallels/Windows 7, and any small change in a Windows document causes the Mac to see the entire Parallels partition to have changed, thus invoking multi-gigabyte backups on a daily or even hourly basis.
