big problem with NETAPP CIFS

Hi Experts,

on my NETAPP FAS2552 I have CIFS running. More or less 2TB are working fine.
Now I have to migrate a folder from my old file server to the CIFS.
Here I talk about 1.3 Million files and nearly 1TB.

When I copy with Robocopy or Teracopy or manually I always have the same issues.
After a while , lets say 1 million files are copied, the system stopped and give me the error:
There is not enough space to copy this file

So I checked the Netapp and I have left more than 1TB.
For a test I copied some file to the NETAPP into another folder and it works.
This error message is not true.
I stopped the copy job and just changed the destination folder name and I can go on and copy files.
Problem is, I need all files in one folder.

Can you help me with this issue on a NETAPP CIFS share ? This is really strange.

how to check the i-nodes or header problem ?
Which command do I need ?
maxfiles is : 31,876,689 -> used: 4,549874
now I was on netapp and wanted to check the maxdirsize limit.

But what is the exact command ?
from the netapp console I have seen now a message :

netapp02> Fri Aug  7 11:19:30 CEST [netapp02:wafl.dir.size.warning:warning]: Directory /vol/Cifs/ASE_WG/V2_WW/Archive4/ is approaching the maxdirsize limit. Reduce the number of files or use the vol options command to increase this limit.

Open in new window

ok problem solved.

I changed MAXDIRSIZE on my volume to +10%
