If it's the bug that Dave's thinking of, it's an issue with md error handling and the BIO_UPTODATE flag, see : http://www.mail-archive.com/linux-raid@vger.kernel.org/msg06628.html For RHEL, this is addressed in Red Hat BZ 512552 https://bugzilla.redhat.com/show_bug.cgi?id=512552 upstream commit c2b00852fbae4f8c45c2651530ded3bd01bde814 Cheers -- Mark _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
