Hi, We had a mount failure when trying to mount an image that was created by the following steps:
1. created a file under '/.' 2. created another file under '/.' 3. run kupdated to flush the log. crash after sectors 0, 1, 3, 5, 6, 7 of the log block (block 3842 in our case) is written out. note that the writes are log writes only. the rest of the disk is intact. so presumably jfs_fsck --replay_journal_only should fix the problem. 4. run jfs_fsck --replay_journal_only on the crashed disk image. it complained sbin/jfs_fsck version 1.1.5, 04-Mar-2004 processing started: 3/20/1933 18.52.48 The current device is: /tmp/junfeng/cmc_blkdev_1_0_jfs_15788 Block size in bytes: 4096 Filesystem size in blocks: 4096 **Phase 0 - Replay Journal Log logredo failed (rc=-269). fsck continuing. Filesystem is clean. After step 4, the attempts to mount this image failed. jfs complained that "Log is Dirty". For some early version of jfs, we got a kernel oops at <2>BUG at jfs_dtree.c:3333 assert((btstack)->top != &((btstack)->stack[MAXTREEHEIGHT])) Run jfs_fsck -p can fix the problem. The crashed image can be downloaded at http://keeda.stanford.edu/~junfeng/crashed.img.bz2 As usual, any confirmation or clarification is appreciated. -Junfeng _______________________________________________ Jfs-discussion mailing list [EMAIL PROTECTED] http://www-124.ibm.com/developerworks/oss/mailman/listinfo/jfs-discussion
