I will see if I can reproduce later this week. Note that I change the domain portion of the hostname, not the short host name. (ie: kp-a10n01.example.org -> kp-a10n01.foo.org). As I mentioned in my reply to Ukrich, I ran fsck.gfs2 after a fresh boot, before starting gfs2, and it found no issues. Note also that this error persisted after reformatting the partition, and after deleting/recreating (with a different size) LV.
