I just tried that and Cluster Validation gives me this error for the intended shared disk (direct lun, attached to two VM's, shareable, privileged scsi): "Disk bus does not support clustering. The required inquiry data (SCSI page 83h VPD descriptor) was reported as not being supported." In the report, the VPD Page 83h identifier is listed as <Unknown>. This seems to be an issue outside of oVirt, stgt only supports this field since version 1.0.46: http://www.spinics.net/lists/linux-stgt/msg04349.html Since I'm running CentOS 6 on the machine that hosts the scsi targets which has 1.0.25, if RedHat hasn't backported that feature, it's not supported. -- Tiemen Ruiten Systems Engineer R&D Media _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
