anyway, the article said to use the default settings in the PILOT tab so i went ahead and repaired the permissions on Mackintosh HD, but that hasn’t fixed the issue either. i got that and went to PILOT tab as suggested, but the only option is to repair permissions on Mackintosh HD. I then looked back at the first article again - and it says to get cocktail disk utility. i have 4 x 2TB disks in it and setup i a high redundancy mode so actual available space is about 5.4TB, and there is 2.62 TB available. its about 50% utilised so definitely no space issues. I checked the tools in drobo dashboard and according to drobo dashboard the disk is healthy. i am sure the first time i verified disk it wasn’t greyed out… but it seems certainly this time it is greyed out HOWEVER, the repair disk button is greyed out. i felt like it should be the drobo dashboard if anything. I have not clicked repair disk because i wasn’t sure if wanted disk utility to start messing with the drobo. i can click on verify disk… when i read the details that come up… in red it says Invalid Node structure, The Volume DroboPro could not be verified completely, the File system check exit code is 8 Error: The disk needs to be repaired, click Repair disk. When i go into disk utility on the imac, and click on the drobo disc… i cannot click on the repair permissions button, its greyed out. as per the first article, i tried using drobo dashboard to shut down the drobopro, then restart my imac and then bring the drobopro back up again. It seems like the issue is to do with permissions. (mac)-cannot-repair-my-drobo-storage-device,-what-should-i-do%3F.I googled this and found these two articles:
