Hello List,
I am using lvm version 2.02.177(2), tried to create a mirrored LV, but failed
with the errors,
tb0307-nd1:~ # pvs

tb0307-nd1:~ # lvcreate --type mirror -m1 -L 500m -n my-lv cluster-vg2
Shared cluster mirrors are not available. <<== failed to create a mirrored
LV
Clustered old mirror needs 'cmirrord' to be installed and running.
Could you help to take a look at this problem? from lvcreate man page, the
mirrored LV is supported by lvcreate.
my lvm2 version/configuration is as below,
