Hi
I wonder that about the pNFS's high availability.
The pNFS will stripe a file on each DSs, so this file will be currupted when one
DS has crushed, will not ?

pNFS over objects can do that, and striping over mirrors, and more.
You need to use: pnfs-client with objlayoutdriver on client, exofs on MDS, and osd-targets
on disk-servers.

spNFS is an exercise in prototyping, useful for testing, and good for
demonstrating the power of the protocol to increase bandwidth. It is
not and has never claimed to be a production file system. There is
no 'fsck'. There is no heart-beat.. There is no stateid recovery, etc.
