Does anyone know the extent to which DMAPI information is handled by
xfsdump/xfsrestore? There are two things that worry me:
1. Are xfsdump/xfsrestore smart enough to realize when data is not resident
on XFS disks? In other words, the data has been migrated by the DMAPI
client, and dm_puch_hole() was used to free up the XFS disk resources.
When doing a dump, I'd rather have xfsdump note that there is a hole rather
than dredging all the migrated data back up through the DMAPI.
2. What do xfsdump/xfsrestore do with DM attributes, regions, and event
lists? Are they stored, ignored, or something else?
I've been able to find only a few clues here and there, though the FAQ
wasn't very helpful. The xfsdump man page mentions a "-a" option for
working with DMF that sounds a lot like an answer to #1, but I'd be
surprised if there was any relationship between DMF and DMAPI.
I would really appreciate any info regarding these questions.
Thanks,
