Hi all, This happens whenever I try to ack a manual fence (which I have to whenever the fence_bladecenter fails, as described in my previous post) : " #fence_ack_manual -n host1.domain.com Warning: If the node "host1.domain.com" 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 file or directory # touch /tmp/fence_manual.fifo # fence_ack_manual -n host1.domain.com Warning: If the node "host1.domain.com" 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 done " Seems a bit weird, and actually fence_ack_manual has worked at some point in time, I am not sure when it stopped working. Any help or pointers to how to diagnose it would be appreciated. Regards -- Denis -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
