One problem that could happen is that the file system is in such a bad state that it can't find /sbin/fsck.jfs, thus logredo can't be run. Are you seeing this type of problem? Couple solutions: 1) have fsck.jfs be loaded by initrd.img. 2) bring the logredo functionality into the file system. > Doesn't that cause problems > with the kernel image of the fs getting inconsistent > with the result of the log replay? > Steve _______________________________________________ Jfs-discussion mailing list [EMAIL PROTECTED] http://www-124.ibm.com/developerworks/oss/mailman/listinfo/jfs-discussion
