<HTML>Hello list Im trying to configure Red Hat Cluster Suite in an enviroment without shared storage to learn how to admin and configure this. Then I using gnbd to simulate a shared storage and I mapped the exported devices in other two RHEL, that are members of the cluster, and bind gnbd devices imported to raw devices to use as quorum shared storage, but when start clumanager the machines reboot, informing the following error in log: Feb 3 14:40:55 parati clusvcmgrd[5133]: <crit> Couldn't read configuration from shared state: Success Feb 3 14:40:55 parati clusvcmgrd[5133]: <alert> Shared State Error: REBOOTING Then I make tests to simultaneos write data in a gnbd device mapped and I note that the files created by one node only appear to other node when the device is reimported and remounted. There are other way to configure RHCS without a shared storage like EMC storages or Sun storages? That are my configuration files for gnbd [root@ilhabela mnt]# cat /etc/sistina/ccs-build/angra.cca #CCA:angra #nigeb=cluster.ccs mtime=1107192495 size=147 cluster { name = "angra" lock_gulm { servers = ["angra"] heartbeat_rate = 0.3 allowed_misses = 1 } } #dne=cluster.ccs hash=BD5C824C #nigeb=nodes.ccs mtime=1107192495 size=177 nodes { angra { ip_interfaces { eth0 = "192.168.1.52" } fence { server { gnbd0 { ipaddr = "192.168.1.52" } } } } } #dne=nodes.ccs hash=72704281 #nigeb=fence.ccs mtime=1107192495 size=78 fence_devices { gnbd0 { agent = "fence_gnbd" server = "angra" } } #dne=fence.ccs hash=9E0446A4 [root@ilhabela mnt]# cat /root/angra/cluster.ccs cluster { name = "angra" lock_gulm { servers = ["angra"] heartbeat_rate = 0.3 allowed_misses = 1 } } [root@ilhabela mnt]# cat /root/angra/fence.ccs fence_devices { gnbd0 { agent = "fence_gnbd" server = "angra" } } [root@ilhabela mnt]# cat /root/angra/nodes.ccs nodes { angra { ip_interfaces { eth0 = "192.168.1.52" } fence { server { gnbd0 { ipaddr = "192.168.1.52" } } } } parati.localdomain { ip_interfaces { eth0 = "192.168.1.56" } fence { server { gnbd0 { ipaddr = "192.168.1.52" } } } } ilhabela.localdomain { ip_interfaces { eth0 = "192.168.1.57" } fence { server { gnbd0 { ipaddr = "192.168.1.52" } } } } } This is the output of gnbd_import -l in both nodes of the cluster [root@ilhabela root]# gnbd_import -l gnbd_import: Device name : hda10 ---------------------- Minor # : 1 Proc name : gnbdb IP : 192.168.1.52 Port : 14243 State : Close Disconnected Clear Readonly : No gnbd_import: Device name : hda9 ---------------------- Minor # : 2 Proc name : gnbdc IP : 192.168.1.52 Port : 14243 State : Close Disconnected Clear Readonly : No gnbd_import: Device name : hda11 ---------------------- Minor # : 3 Proc name : gnbdd IP : 192.168.1.52 Port : 14243 State : Open Connected Clear Readonly : No This is the content of /etc/sysconfig/rawdevices [root@ilhabela root]# cat /etc/sysconfig/rawdevices # raw device bindings # format: <rawdev> <major> <minor> # <rawdev> <blockdev> # example: /dev/raw/raw1 /dev/sda1 # /dev/raw/raw2 8 5 /dev/raw/raw1 /dev/gnbd/hda9 /dev/raw/raw2 /dev/gnbd/hda10 Partition /dev/gnbd/had11 is ext3 and are mounted in both nodes, but the data write for one node only is acessible to other when the device is reimported and remounted.
