IBM N3220 - 2857-A22 (NetApp FAS2240-2) Data ONTAP Release 8.1.2P1 7-Mode
We are trying to move a share from a EMC CX4 to a nSeries system. The method for moving is to mount both shares to a Win server and robocopy.
The application using this share has a BUG - it creates little files and NEVER deletes them. There is now almost 10m files in the share, almost all of them in one directory. This bug won't be resolved anytime soon.
==> PROBLEM
The robocopy runs, then fails with out of space condition. The filer gets the following these messages - all the same - all for the same directory "Resubmitted".
___ Thu 06 11 17:28:28 EDT [isnapr0664a:wafl.dir.size.max:warning]: Directory /vol/v_prdieeapp_cifs/q_prdieeapp_cifs/XXXXData/Data/HVRI/Resubmitted/ reached the maxdirsize limit. Reduce the number of files or use the vol options command to increase this limit.
==> Comments/Questions
So we've hit the maxdirsize on something, but on what?
The Win admin doing the robocopy ran TreeSize Professional on both shares, and it looks like the copy is almost complete. The REALLY WEIRD THING is that the dir "WorkBIn" with +8m files did NOT get any errors. But the dir "Resubmitted" with +470k files DOES get the errors.
Q) Why would we hit maxdirsize on a dir with +460k files, but not hit maxdirsize on a dir with +8m files?
Q) Is maxdirsize for an entire dir structure, or, for an individual dir?
I have a case open with IBM support, but not getting very far.

1. Directories never shrink so it is possible that it had many entries which are now deleted. Also it is the size of directory file, not number of entries, which counts. I.e. long names would consume more space (although this is less likely with such difference).
2. maxdirsize is global per volume.
