[Pvfs2-developers] bufmap_copy_iovec errors?

[Sam Lang]

Hi Kyle,

I don't have a fix for your problem yet, but I think the message  
about "Please make sure that the pvfs2-client is running" is  
erroneous.  The real error is the pvfs_bufmap_copy_iovec_from_user  
error.

Also, did you pull from CVS using the pvfs-2-6-0 release tag?  If  
not, the code in trunk (HEAD tag) may not be working for ppc64 at  
this point.
