Hi Emmanual,
I haven't had a chance to look at what specifically went wrong with NFS
access in this case, but I think in general there is an issue with how
NFSv4 expects us to use iget to resolve inodes.
I suspect it will be fragile unless we implement the file handle
functions described here:

Hi, how I've mentioned in a previous post, NFS doesn't work over pvfs2
filesystems now. It was close to work with some development versions
around 2.7.0, but currently it's completely unoperative with 2.7.1:
/usr/src/pvfs-2.7.1/src/kernel/linux-2.6/pvfs2-utils.c line 464:
Critical error: Invalid handle despite using iget4/iget5
I don't quite understand the error; it's occuring in the
pvfs2_inode_getattr() function, each time I try to read or write a
file, though a "ls -l" (which calls for "getattr()?") works.
Is NFS kernel server doing iget4/5_locked access? I tried to sort it
out unfortunately I don't know where HAVE_IGET4_LOCKED is defined (I
suppose somewhere in the kernel source).
May it be a compatibility problem with the kernel release I'm using
(2.6.22.19)?
