You should investigate in your /var/log/messages why this happened. It is usually a sign of filesystem corruption or disk errors, so you would likely also need to run e2fsck before remounting the filesystem. Doing the unmount/mount of just the OSTs should be enough Cheers, Andreas -- Andreas Dilger Sr. Staff Engineer, Lustre Group Sun Microsystems of Canada, Inc. _______________________________________________ Lustre-discuss mailing list Lustre-discuss@lists.lustre.org http://lists.lustre.org/mailman/listinfo/lustre-discuss
