Paul in regards to your question I would think you want to use NFSv4 ACLs and set the chmodAndUpdateAcl option on the fileset (see mmcrfileset/mmchfileset).

Ganesha only supports NFSv4 ACLs, so the conversion is a quick one. kernel NFS server converts NFSv4 ACLs to POSIX ACLs (the mapping isn't perfect) as many of the Linux file systems only support

Thanks Paul. Could you please clarify which ACL you changed, the GPFS NFSv4
ACL or the POSIX ACL?

I thought Spectrum Protect didn't actually backup again on a file owner change.
Sure mmbackup considers it, but I think Protect just updates the metadata.
There are also some other options for dsmc that can stop other similar issues
if you change ctime maybe.
(Other backup tools are available)

You do
We are in the process of changing the way GPFS assigns UID/GIDs from internal
tdb to using AD RIDs with an offset that matches our linux systems.
We, therefore, need to change the ACLs for all the files in GPFS (up to 80
million).
We are running in mixed ACL mode, with some POSIX and some NFSv4
17 matches
