I have the following cluster.conf:
<?xml version="1.0"?>
<cluster name="GFSCL" config_version="2">
<cman two_node="1" expected_votes="1">
</cman>
<clusternodes>
<clusternode name="nd1">
<fence>
<method name="single">
<device name="human1" nodename="nd1"/>
</method>
</fence>
</clusternode>
<clusternode name="nd2">
<fence>
<method name="single">
<device name="human2" nodename="nd2"/>
</method>
</fence> </clusternode>
</clusternodes>
<fencedevices>
<fencedevice name="human1" agent="fence_manual"/>
<fencedevice name="human2" agent="fence_manual"/>
</fencedevices>
</cluster>
Iam trying to set up a two node cluster with shared storage and I have /dev/hda3 of 5GB for testing.
First I have instaled cluster, dm, and LVM with the specified "parameters" (specified in the usage.txt)
I have done modprobe for:
lock_dlm, dlm, cman, gfs, lock_harness
with both nodes started i have tried
ccsd
cman_tool join -w
fence_tool join -w
clvmd
and I started to create the lv:
pvcreate /dev/hda3
vgcreate vg /dev/hda3
and when I tried to do lvcreate -L 100 vg i get this error:
"Error locking on node nd2: Internal lvm error, check syslog
F! ailed to activate new LV"
When I check syslog there are no errors...and I have a lv created /dev/vg/lvol0
and I can activate the lv bt vgchange -aly....
Have I done something wrong ?
Can I have shared storage using this method ? I want my nodes to have identical data on one drive and this one to be updated only on one node.
Thanks,
