If you want to try to fix the superblock, you can create a sparse file that is the same size as the volume:
dd if=/dev/zero of=/somefile bs=4096 seek=1172111359 count=1 Then run "mkfs -tjfs /somefile" Then copy the superblock: dd if=/somefile of=/dev/VolGroup00/lvol0 bs=4096 skip=8 seek=8 count=1 I can't guarantee how much further fsck will get, but it may be worth a try.

But then again, jfs_debug bases this on the block size s_bsize, so who knows where it's reading from. > I'd be happy to give you a login on this machine if you want to try to > debug it. Let me know if fixing the superblock makes any progress. -- David Kleikamp IBM Linux Technology Center _______________________________________________ Jfs-discussion mailing list [email protected] http://www-124.ibm.com/developerworks/oss/mailman/listinfo/jfs-discussion
