This is head r242707 but the original pool is quite old and has been moved around a fair bit using send|recv. I've never intentionally used extended attributes but the pool has been exported to Windows XP via Samba and OS-X via NFSv3. If anyone has any ideas for repairing the pool, I'd be interested. --=20 Peter Jeremy --VywGB/WGlW4DM4P8 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iEYEARECAAYFAlCm2mUACgkQ/opHv/APuIfWlACfYVPRz3kxtwFzlNSZe+FxXnjh bSYAoKIi0QmdrcqHsIOdjV1KQANEerHH =CitQ -----END PGP SIGNATURE----- --VywGB/WGlW4DM4P8--
