Hmmm... I've seen this issue once before and on a similar setup. As in, firewire (Oxford 911 chipset). It literally is a one-bit corruption. The signature INODE01 becomes KNODE01. As far as I remember we never could duplicate it. As it was only on one firewire setup and not on any fiber/iscsi/xen setups, we did not spend much time on it.
First, backup: dd if=/dev/sdX of=/tmp/backup bs=<blocksize> count=1000 To fix: # dd if=/dev/sdX of=blk17 count=1 skip=17 bs=<blocksize> # dd if=/dev/sdX of=blk23 count=1 skip=23 bs=<blocksize> Use your favorite bin editor and change the first K to an I. # dd of=/dev/sdX if=blk17 count=1 seek=17 bs=<blocksize> # dd of=/dev/sdX if=blk23 count=1 seek=23 bs=<blocksize> The fs should be umounted during this escapade. Also, maybe you should look at iscsi for your shared storage needs.
