[gpfsug-discuss] Feature Request: Clones Inheriting XATTRS

HI All,

Where do I send feature requests?

I'd like the mmclone command to have a switch which allows user defined attributes to be passed to file clones. I can understand why the "gpfs." defined extended attributes don't get passed along, because they might hold special information like how a DMAPI agent has fiddled with the data, which won't necessarily hold true for clones.

However, what would be really useful is something like "--xattr" switch for mmclone, which allows "user." defined attributes to be inherited by clones.

We are intending to use file cloning as an internal data sharing mechanism (to reduce physical disk space usage). Some scientific groups may wish to pass along all the extended attributes (e.g. instrument type, serial number, experiment ID, etc.) to those they share data with, and others may wish to strip out those attributes.

Where shall I send this one?

Cheers,
Luke.
