Too bad I haven't got a 100 TB machine at hand. However I have a 24TB system dedicated to tests.

Stay tuned :) --=20 ------------------------------------------------------------------------ Emmanuel Florac | Direction technique | Intellique | | +33 1 78 94 84 02 ------------------------------------------------------------------------ --Sig_/_1fLZiziONhlE401MG3.ibF Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkxtLVoACgkQX3jQXNUicVYdkwCg2e/nPbuckZSnq8IptdJsRnmw fEMAoOpym/fDALIw1uisvTGp1B72gv+Q =sYp5 -----END PGP SIGNATURE----- --Sig_/_1fLZiziONhlE401MG3.ibF-- --===============4489664161513717915== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs --===============4489664161513717915==--
