Hello - Current xfs_repair uses a brute force approach to find a valid secondary sb. This series optimizes the secondary sb search, using similar method to determine geometry as that of xfs_mkfs. If the faster method fails in its search, fall back to original brute force slower search. patch 1 has some general infrastructure adjustments, moving general topology functions from mkfs to libxcmd. patch 2 adds the new secondary superblock search method. Questions, comments are welcome. Thanks- Bill _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
