How can I activate cmirrord to carry out a pvmove in a RHEL 7 Resilient Storage cluster without having to restart my resources or applications?

RHEL 6

pvmove of clustered volumes is supported on all releases of RHEL 6 with the requirement that cmirror be installed and cmirrord service be started on all nodes.

# service cmirrord start
RHEL 5

pvmove of a clustered volume is supported In RHEL 5 if:

  • The following packages are installed:
    * lvm2-cluster version lvm2-cluster-2.02.40-7.el5 or higher
    • kmod-cmirror
    • cmirror
  • The cmirror daemon is started on all nodes

The components to support cmirror were released with RHEL 5 update 3.

The cmirror-kmod package that must be installed depends on the kernel that is running. For example, if the running kernel is kernel-largesmp, it is necessary to have cmirror-kmod-largesmp for the corresponding kernel version.
