The storage is fronted by a switch, the SCSI errors occur after the Queue_Full warning which seems to initiate the problem. In this context, what does Queue_Full mean? -----Original Message----- From: linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of Michael Conrad Tadpol Tilstra Sent: Wednesday, May 18, 2005 8:36 AM To: linux clustering Subject: Re: GFS Problem On Tue, May 17, 2005 at 11:39:08PM -0600, Frank L.

You are getting scsi errors which are completely confusing gfs, and causing it to panic. -- Michael Conrad Tadpol Tilstra To err is human, to really foul things up requires a computer. -- Linux-cluster@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/linux-cluster
