The options for ACL's on GPFS are POSIX, NFSv4, all which is mixed NFSv4/POSIX and finally Samba. The first two are self explanatory. The mixed mode is best given a wide berth in my opinion. The fourth is well lets say "undocumented" last time I checked. You can set it, and it shows up when you query the file system but what it does I can only speculate. Take a look at the Korn shell of mmchfs if you doubt it exists. Try it out on a test file system with mmchfs -k samba My guess though I have never verified it, is that it changes the schematics of the NFSv4 ACL's to more closely match those of NTFS ACL's. A bit like some of the other GPFS settings you can fiddle with to make GPFS behave more like an NTFS file system. JAB. -- Jonathan A.
