Nope, no stack trace was produced that I was able to see. And yeah, I would have preferred to have one, myself. I'll check into the suid thing. It's entirely possible one of my users did something like that, since many of them have root on their desktop linux machines. -- Jerry Gilyeat, RHCE Systems Administrator Molecular Microbiology and Immunology Johns Hopkins Bloomberg School of Public Health -----Original Message----- From: linux-cluster-bounces@xxxxxxxxxx on behalf of Benjamin Marzinski Sent: Tue 9/20/2005 4:26 PM To: linux clustering Subject: Re: Question... You didn't perhaps get a stack trace along with that message, did you? That would go a long way in figuring out what exactly went wrong. But here's a wild stab in the dark. Do you know if a suid root file was being copied to your gfs file system? That has caused a similar error on other versions of gfs (although not with nfs). -Ben On Tue, Sep 20, 2005 at 02:15:39PM -0400, Gerald G.
