Re: Problem mit GFS Einrichtung
Hallo,
ich habe es selbst geordnet bekommen. Ich hab hierfür auf LVM
verzichtet. Für die Archive hier mein Vorgehen (Quelle:
http://www.piemontewireless.net/Storage_on_Cluster_DRBD_and_GFS2):
# apt-get install gfs-tools gfs2-tools
# cat /etc/cluster/cluster.conf
<?xml version="1.0"?>
<cluster name="cluster" config_version="1">
<!-- post_join_delay: number of seconds the daemon will wait before
fencing any victims after a node joins the domain
post_fail_delay: number of seconds the daemon will wait before
fencing any victims after a domain member fails
clean_start : prevent any startup fencing the daemon might do.
It indicates that the daemon should assume all nodes
are in a clean state to start. -->
<fence_daemon clean_start="1" post_fail_delay="0" post_join_delay="3"/>
