CIFS share and max sub directory limit reached

[Darren Etheridge_2]

We are running 11.23 with Online JFS. We have a CIFS share with millions of images and have reached the 32766 sub-directory limit. Is there a fix for this? If so, where is it? I've looked in the kernel parameters, but can't see it. If there is a fix, and I ever have to move this directory (with thousands of subdirectories and millions of files) to another OS, will this pose a problem on another OS.. say Linux? or Windows 2008?

Thank you!!!

Hi Darren:

You can double the limit but that's as far as you can go.

# kctune -s vx_maxlink=65534

The default value is 32767 with a maxium value of 65534.

That said, having a filesystem with "millions of files" and such a very large number of directories is certainly not going to yield optimal performance. Databases are better suited for such orders of magnitude.

Thank you!!. we are moving all the files out of an Oracle database (BLOBS) to flat files and migrating the data (indexes) to SQL. So the image will be indexed by SQL. But thank you, I'll have to figure out another way to export the files to a differential directory structure (ie after 32000 directories- create another main directory (ie. AR-FILES1) and create the remaining subs under there.
