Hi Folks RHEL 5.2 gfs2-utils-0.1.44-1.el5_2.1 kmod-gfs-PAE-0.1.23-5.el5 gfs-utils-0.1.17-1.el5 kmod-gfs2-PAE-1.92-1.1.el5 5 nodes in a cluster just using GFS over iSCSI. Were getting the following error in /var/log/messages - Feb 11 09:17:00 finapp1 gfs_controld[7084]: plock result write err 0 errno 9 Feb 11 09:17:08 finapp1 gfs_controld[7084]: plock result write err 0 errno 9 Feb 12 13:02:25 finapp1 gfs_controld[7084]: plock result write err 0 errno 9 Feb 12 13:02:32 finapp1 gfs_controld[7084]: plock result write err 0 errno 9 And the users are complaining that Oracle occasionally runs slow. Could anyone help to explain what these errors mean please ? Thanks, Nick . -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
