I have a DM application that uses XFS and dmapi. I need a way to keep
xfsdump from triggering a data fault on files that have holes punched in
them. I see that xfsdump has code that knows about DMF attributes, and
it will avoid triggering DMF data faults if run with the "-a" option. I
am (not surprisingly) not using an attributes strategy identical to
DMF's, so this doesn't work for my app.
Before I tunnel through the whole implementation of xfsdump, I'm hoping
the dmapi/xfsdump developers could make suggestions as to the best
approach for getting "-a" behavior with my app. Without going overboard
to "spoof" DMF behavior, is there a way of doing it without modifying
xfsdump? If I do need to patch xfsdump, suggestions appreciated as to
the best approach.
Thanks,
John Groves
