For the most part, XFS is used for massive filesystems (hundreds of petabytes)
successfully in Linux (among other OS's). However, Mr. Newman still believes
there are details that he believes XFS doesn't include or Linux limits (such as
page sizes in x86 limiting block sizes).
With that preface, here are some questions:
-Is XFS fully RAID aware inthat it aligns metadata with RAID stripes? Some of
the information I see states XFS can get geometry information from LVM and MD,
but what about hardware RAID?
-Does XFS take advantage of T10 DIF (block protection?)?
-Does/Will XFS support NFS v4.1?
-Concerning the block-size limit, will this eventually be a thing of the past?
Mr. Newman's contention is massive filesystems should have much larger block
sizes, but he also contends that OSD is the eventual answer instead of using
block allocation.
-Is there anything else y'all would like folks to understand about XFS and
massive implementations?
Thanks!
