Errr... I'm at a loss as to how you could have gotten this error message. There is no assertion like that in inode.c. The timestamp that GFS printed out "time = 1095145469" is no where near Oct 24 11:04:29. The panic message looks suspiciously similar to one posted in September when someone forgot to recompile their lock_harness module. https://www.redhat.com/archives/linux-cluster/2004-September/msg00075.html Maybe you had a cut-and-paste error? -- Ken Preslan <kpreslan@xxxxxxxxxx>
