I would be interested to know what you chose for your filesystems and
user/project space directories:
* Traditional Posix ACL
* NFS V4 ACL
We use traditional Posix ACLs almost exclusively.
The main exception is some directories on Spectrum Scale where Windows
machines with native Spectrum Scale support create files and
directories. There our scripts set Posix ACLs which are respected on
Windows but automatically converted to NFS V4 ACLs on new files and
directories by the file system.
What did motivate your choice?
Mainly that our use of ACLs goes back way longer than our use of
GPFS/Spectrum Scale and we also have other file systems which do not
support NFSv4 ACLs. Keeping knowledge and script on one set of ACLs
fresh within the team is easier. Additional headache comes because as we
all know Posix ACLs and NFS V4 ACLs don't translate exactly.
We are facing some issues to get the correct NFS ACL to keep correct
attributes for new files created.
Is this using kernel NFSd or Ganesha (CES)?
