Anyone know the best way to check/verify a Drobo 5D filesystem using the macOS Disk Utility? While I know how to use Disk Utility to verify a filesystem I’m running into an issue where I’ve booted my Mac in normal mode and when I try to do the verification on the 5D DU reports that it is unable to unmount the 5D because it is in use. That makes sense because I have several services like the Time Machine Server using the 5D for storage. I would like to avoid having to disable all such services in order to do the file system check. Does booting in single user mode help with this?
Note that the 5D is currently attached to my Mac via thunderbolt. I have tried booting in recovery mode then running DU but it does not see the 5D.
