:Ahh, yes, I am exporting PFSs, I didn't know it isn't supported (yet)!
:
:I will move data in HAMMER file system on my nfs server out of PFSs and ret=
:est;
:it is going to be a few hours before files are moved, stay tuned.
:
:Will send requested info if problem persists.

:PS: Now I won't bug that export of PFS root isn't possible (symlink);
:but I guess that will change anyway.

    I have some hacks in there to try to support it but there are issues.
    I definitely want to support exporting PFSs for 2.2.

    I think half of the problems are related to that dotdot vop.  I get
    weirdness just trying to mount an exported PFS.

    The other issue is that HAMMER has only one netexport structure... it
    really needs one for each PFS.  And I don't think NULLFS (for nullfs
    mounts of the PFSs) does the pass-through quite right.

    Please do re-test.  I want to be sure that this is a PFS issue and not
    a general HAMMER issue.
