Just tried. (1) reboot l6-z-5 (2) fenced error messages are repeatedly written to /var/log/syslog on l6-z-12 (3) from l6-z-12, ack manual fencing using "fence_ack_manual -n l6-z-5". Gives: "Warning: If the node "l6-z-5" has not been manually fenced (i.e. power cycled or disconnected from shared storage devices) the GFS file system may become corrupted and all its data unrecoverable! Please verify that the node shown above has been reset or disconnected from storage. Are you certain you want to continue? [yN] y can't open /tmp/fence_manual.fifo: No such device or address" (4) fenced error messages are still repeatedly written to /var/log/syslog. So acknowledging the manual fence operation didn't help at all. Actually I don't think fenced has called fence_manual, because there's no syslog message indicating that fence_manual was called. And I get such messages when I manually call fence_manual. Thanks, -- Eric -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
