Also, the path passed into nmount() is not the path I was mounting (though it is a path I tried unsuccessfully to mount yesterday). Has anyone got any suggestions? Just before I sent this, I tried the mount again and got EPERM on the client. Since I'd been renaming ZFS mountpoints, I assumed that mountd had gotten itself confused. When I SIGHUP'd it, I got another identical panic. --=20 Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour. --3Gf/FFewwPeBMqCJ Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAklXXmMACgkQ/opHv/APuIeG6QCeOoWNC5/o1jrlfjYjGemRcI1I slgAmgNfBrDa5ahQXII2fssXuhKwQAOf =MyIL -----END PGP SIGNATURE----- --3Gf/FFewwPeBMqCJ--
