hi, while i do not have a mac, i have had some cases where on windows i needed to do a full shutdown and reboot.
have you tried that, and then when your system is rebooted, to try just deleting the unwanted folder (but without going into that folder)?
thanks clay, i think if a reboot (and then trying to delete that folder without accessing its content did not help)
and if the other guys suggestion of a mac safeboot mode wasnt able to delete it either,
then can i check if your mac is directly connected to the drobo, or does it go through another switch or device?
(if so, maybe trying a direct connection, and rebooting as well, might do the trick?)
was the name of the offending folder, a name that you created? (or was it possibly created by another program of process with a certain pre-determined name?)
oh ok clay,
as i do not actually have a mac we might need to wait for some of the mac veterans
but just as a simple thought… what if you were to simply make it a hidden folder, for now at least, (especially if the actual folder or icon is not taking up any space?)… that way it would no longer be “in your face” in a manner of speaking, and no longer a visual niggle?
On occasion, I have had a file or folder in a share that will simply not be deleted, no matter what. Frustrating, and has happened more than once.
My solution - after all else has failed? Within the Drobo Desktop, create a new share to replace the share with the problem. Then in you file manager (Finder in macOS, or File Explorer in Windows) copy all the good folders and files from the problem share [BAD_SHARE] into a newly created share [GOOD_SHARE], but don’t copy the problem folder(s) or file(s). Now that you have duplicated your share minus the problem folder, just ERASE [BAD_SHARE]. As a final step, you can rename [GOOD_SHARE] to the original name of the deleted [BAD_SHARE], if desired.
Easy to accomplish, but sometimes, not so obvious.
that gave me another idea too… on windows, there is a tool called process explorer.
(often, if i try to compress or move an installer file such as .exe, windows explorer locks the file as well as antivirus, until the explorer process has closed and about 5 mins have passed).
one thing you (and clay) could try, is a similar tool (for mac) or if you are on windows, is process explorer, to search for the filename or folder and it will show you all the processes that are using or accessing it some way.
(for me, it was simply an explorer instance with handles that i could close safely, but a tool like that might help to give a bit more insight into what possibly locks it in the first place).
