Hi,

I hope this is the proper forum for NFS PNFS related questions, if not can
you please point to the proper mailing list.

I have couple of questions regarding PNFS block layouts:-

1) Is there any limitation in Linux client regarding number of segments in
layoutget that it can handle for block layouts? By segments I mean any
limit on number of entries in blo_extents on client side

/// struct pnfs_block_layout4 {


 /// pnfs_block_extent4 blo_extents<>;


/// /* extents which make up this /// layout. */

 /// }; ///



2) I see that the Linux server recalls(RECALLCONFLICT) the layouts for
clients if there are more than one client requesting for iomode of
even READ for an overlapping range ? Any reason why iomode of READ should
result in conflict ?

Any pointers would be helpful.

Thanks,
Sunil Bhargo
