Creating a Mirrored LVM Logical Volume
Hi:
did any know how to create mirrored LVM logical Volume?
I try to follow this instrution on step 2. which is "verifies that the clvmd
daemon is running"
but I don't see deamo running.
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Logical_Volume_Manager_Administration/mirvol_create_ex.html
and then I run "chkconfig clvmd on " and service clvmd start" I got this message:
clvmd could not connect to cluster manager
Consult syslog for more information
please help me.
Thanks
Danny

Hi Danny,
If you are configuring the LVM mirror on single node (and not in a cluster) you can skip steps 1,2,3 and 4 from
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Logical_Volume_Manager_Administration/mirvol_create_ex.html
as cmirror is only require on all the nodes when you have a cluster.
For details on cluster configuration and administration please see
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html-single/Cluster_Administration/index.html

Hi Danny,
Do you want to build a cluster?
And do you want to share the Logical Volumes between the servers, or do you just share the SAN boxes but no data sharing?
For the situation is not clear.
If you want to build a cluster you need set it up first before you can do the lvm mirroring.
If no cluster is required, just share the boxes, but no data sharing, skip the cluster mirror steps.
Kind regards,

- Ricci Hostname?

I case of RHEL 5 this is the root password of the system. If using RHEL 6, we assign a separate password for the ricci.
