Question on GPFS VFS

[miguel.sanders at arcelormittal.com]

Hi guys

I have been using Samba quite a long time with a GPFS backend for shares without problems.
However, when I compiled Samba back then, I didn't compile GPFS support with it.
Moreover I only use traditional ACLs on GPFS exported shares (no NFSv4 ACLs).

I have been reading that you should use the GPFS VFS when using GPFS exported shares because of possible data corruption.
Is this true? Is there also a performance benefit when using GPFS VFS? Are they other things I should take into account?

Thanks for clarifying.

Met vriendelijke groet
Best regards
Bien à vous
