[gpfsug-discuss] mmapplypolicy on nested filesets ...

[Jaime Pinto]

A few months ago I asked about limits and dynamics of traversing  
depended .vs independent filesets on this forum. I used the  
information provided to make decisions and setup our new DSS based  
gpfs storage system. Now I have a problem I couldn't' yet figure out  
how to make it work:

'project' and 'scratch' are top *independent* filesets of the same  
file system.

'proj1', 'proj2' are dependent filesets nested under 'project'
'scra1', 'scra2' are dependent filesets nested under 'scratch'

I would like to run a purging policy on all contents under 'scratch'  
(which includes 'scra1', 'scra2'), and TSM backup policies on all  
contents under 'project' (which includes 'proj1', 'proj2').

HOWEVER:
When I run the purging policy on the whole gpfs device (with both  
'project' and 'scratch' filesets)

* if I use FOR FILESET('scratch') on the list rules, the 'scra1' and  
'scra2' filesets under scratch are excluded (totally unexpected)

* if I use FOR FILESET('scra1') I get error that scra1 is dependent  
fileset (Ok, that is expected)

* if I use /*FOR FILESET('scratch')*/, all contents under 'project',  
'proj1', 'proj2' are traversed as well, and I don't want that (it  
takes too much time)

* if I use /*FOR FILESET('scratch')*/, and instead of the whole device  
I apply the policy to the /scratch mount point only, the policy still  
traverses all the content of 'project', 'proj1', 'proj2', which I  
don't want. (again, totally unexpected)

QUESTION:

How can I craft the syntax of the mmapplypolicy in combination with  
the RULE filters, so that I can traverse all the contents under the  
'scratch' independent fileset, including the nested dependent filesets  
'scra1','scra2', and NOT traverse the other independent filesets at  
all (since this takes too much time)?

Thanks
Jaime


PS: FOR FILESET('scra*') does not work.
