Hi Bryan
Unsure, to be honest. When I added all the GPFS UG RFEs in, I didn't
see an option to make the RFE private.
There's private fields, but not a 'make this RFE private' checkbox or such.
This one may be better directed to the GPFS developer forum / redo the RFE.
RE: GPFS UG RFEs, GPFS devs will be updating those imminently and we'll
be feeding info back to the group.

I reviewed my RFE request again and notice that it has been marked as
“Private” and I think this is preventing people from voting on this
RFE. I have talked to others that would like to vote for this RFE.
How can I set the RFE to public so that others may vote on it?
Thanks!

A DMAPI daemon solution puts a dependency on the DMAPI daemon for the
file system to be mounted. I think it would be better to have
something like what I requested in the RFE that would hopefully not
have this dependency, and would be optional/configurable. I’m sure we
would all prefer something that is supported directly by IBM (hence
the RFE!)
Thanks,

Ps. Hajo said that he couldn’t access the RFE to vote on it:
I would like to support the RFE but i get:

The only DMAPI agent i am aware of is a prototype that was written by
tridge in 2008 to demonstrate a file based HSM system for GPFS.
its a working prototype, at least it worked in 2008 :-)
you can get the source code from git :
http://git.samba.org/rsync.git/?p=tridge/hacksm.git;a=summary
just to be clear, there is no Support for this code. we obviously
Support the DMAPI interface , but the code that exposes the API is
nothing we provide Support for.
thx. Sven

I agree with Ben, I think.
I don’t want to use the ILM policy engine as that puts a direct
workload against the metadata storage and server resources. We need
something out-of-band, out of the file system operational path.
Is there a simple DMAPI daemon that would log the file system
namespace changes that we could use?
If so are there any limitations?
And is it possible to set this up in an HA environment?
Thanks!

querying this through the policy engine is far to late to do any thing
useful with it

The rudimentaries for this already exist via the DMAPI interface in
GPFS (used by the TSM HSM product). A while ago this was posted to the
IBM GPFS DeveloperWorks forum:

share the code once it is working.
