I think Lustre group wants or was directed to arrange for ZFS becoming
a supported backing store. Since Lustre might have less
interoperability baggage than NFS, SMB, iSCSI, maybe you could
convince them to extend the ZFS-checksum protection domain out to the
Lustre client. I don't really know what they are doing. It might end
up without quite the level of elegance of a ZFS checksum tree since
there will be multiple ZFS's beneath Lustre, but adding the idea of a
``protection domain'' to their deliberations might make Lustre-ZFS
meaningfully better.
