<br>between GPFS ACL's and the ACL format as used by Ganesha. My <br>understanding was one of the drivers for using Ganesha as an NFS server
<br>with GPFS was you can write a FSAL to do just that, in the same way as
<br>on Samba you load the vfs_gpfs module, unless you are into self <br>flagellation I guess.<br><br><br>JAB.<br><br>-- <br>Jonathan A. Buzzard
