[gpfsug-discuss] filesets inside of filesets

Wed Sep 6 13:51:47 BST 2017

Hello Damir,

the files that belong to your fileset "backup" has a separate quota, it is
not related to the quota in "b1000".
There is no cumulative quota.

Fileset Nesting may need other considerations as well, in some cases
filesets behave different than simple directories.
-> For NFSV4 ACLs, inheritance stops at the fileset boundaries
-> Snapshots include the independent parent and the dependent children.
Nested independent filesets are not included in a fileset snapshot.
-> Export protocols like NFS or SMB will cross fileset boundaries and just
treat them like a directory.

Mit freundlichen Grüßen / Kind regards

Subject:	[gpfsug-discuss] filesets inside of filesets
Sent by:	gpfsug-discuss-bounces at spectrumscale.org

Today we have following fileset structure on our filesystem:

/projects <-- gpfs filesystem

/projects/b1000 <-- b1000 is a fileset with a fileset quota applied to it

I need to create a fileset or a directory inside of this project and have
separate quota applied to it e.g.:

/projects/b1000 (b1000 has 10TB quota applied)
/projects/b1000/backup (backup has 1TB quota applied)

Is this possible? I am thinking nested filesets would work if GPFS supports
that. Otherwise, I was going to create a separate filesystem, create
corresponding backup filesets on it and symlink them to
the /projects/<projectname> directory.

Thanks in advance.
