Drobo

Folder disappears after attempt to rename

Can anyone please shed light on a strange happening? I have a Drobo and Droboshare. This morning I attempted to rename one of the folders on the Drobo drive and the folder has completely disappeared. I cannot find it in trash and there is no sign of it in Finder. I have checked invisible files and there is a .-FILENAME file relating to the missing folder. I cannot think that the folder has been deleted and I wonder if anyone can help.

how did you try to rename it? in the Finder or directly on Droboshare?

I opened the Drobo window in Finder, highlighted the folder and then typed in the new name when the highlight changed. This is my normal practice and I’m not sure how I would do the change directly on Droboshare. I’ve been away from the computer for six hours and half expected the folder to reappear but it hasn’t done so. I don’t understand how it can just disappear like that and it is quite worrying (especially since it is my only copy of this particular folder, containing all my archive material!)

I was asking because I had a similar issue once but I did the rename directly on Droboshare (ssh to Droboshare, then “mv xxxx yyyy”). What I changed in the directory name was only the case (e.g. “mv mydir MyDir”). At that time I did not realize that the droboshare filesystem is not case sensitive. Instead of returning an error message, the “mv” command killed the directory. I don’t know if the issue was only because of the “case problem” or in combination with “mv”. That was an older version of the firmware. I ran Disk Utility but I can’t remember if was I able to recover all the data.

This may be a pointer. I was also trying to change the case–from ARCHIVES to Archives–purely for cosmetic reasons. I also didn’t realise that the file directory on Drobo was not case-sensitive and this may account for the problem. Anyway, I’ve sent a support request on this one and will see if I can get any help. I’m only glad I did not try to do this on a current and more important data.

Having said all this, the Drobo is supposed to be a fail-safe system and it should not be possible to cause mayhem simply by trying to rename a file or folder. It’s also difficult to believe that an entire folder can just disappear without trace. There could be a more simple explanation and I will await the response.

Thanks for your interest and help.

Here’s another data-point.

I just tried this on my DroboShare (fw 1.1.2 [51.14990]) attached to Drobo (gen 2) (fw 1.3.5 [1.252.21110])
Drobo is formatted as NTFS (“new” version, 16 TB)
Client is Windows XP SP 3 (32-bit)

Created folder called TESt folder
Populated it with files.

Renamed TESt folder to Test Folder in Windows Explorer.
Worked fine. Contents are still there.

Just to check if long filenames was an issue, I also tried naming the folder TEST (and verified via DIR /X that there is no special 8.3 filename associated) then renaming to Test. Worked OK again.

Tried the same in Command Prompt, for kicks. Worked OK.

So seems it might be a Mac OS issue?
I know in Mac OS, overwriting a folder will completely overwrite it, not merge the two like Windows does.

Thanks. It could well be an OS X issue. I am in contact with Drobo support who have suggested repairing the disk using Disk Utility. I will give that a try and see what happens.
