Since I would be needing GPFS support for Samba on AIX (mainly for ACLs), I made some modifications to the GPFS VFS code in order to get this to work on AIX aswell. It should be noted however that certain calls in the GPFS GPL libs were solely made for Samba (on Linux) and were not ported to AIX (even though the entrypoints are available). Moreover some of those calls dump core (illegal opcode). This has been reported to the L3 GPFS people. This will be fixed in a future release in which those functions will simply return ENOSYS on AIX.

Miguel, I have a few fixes I'd like to try out with you. They are
slightly along the lines you've outlined, but there is also a mistake in
the 3.2 packaging of GPFS from IBM starting at update 8. I have a fix
for that as well.
I'm working the problem on my servers at the moment and will need a few
more days to iron out the steps (it's almost holiday!)
