One of our home directory directories was inadvertently set to mixed mode and now I'm having problems deleting sub-dirs from it. Many of the directories appear to be empty both on the NFS and CIFS side yet ls shows them containing more than 4k but even the ones that are 4k do not let me delete them. It's not every directory (I've been able to delete ~500) but the ones remaining I cannot get rid of either as root on the NFS side or with Domain Admin rights.
One last interesting thing is that if I try to force change the rights it says the path is \host\UserDirectorynane (missing the \ before Directoryname) in the Windows UI. Kind of scary, I've never seen this before.
I would not be terribly surprised if there was not some file system corruption here, there where a LOT of files in this directory and it's children at one point. I've never seen that happen on a filer before but if it were going to happen this is the place.
