Using the SmartMove™ feature while attaching a plex
The SmartMove™ feature reduces the time and I/O required to attach or reattach
a plex to an existing VxVM volume, in the specific case where a VxVM volume
has a VxFS file system mounted on it. The SmartMove feature uses the VxFS
information to detect free extents and avoid copying them.
To turn on the SmartMove feature, specify usefssmartmove=all in the file
/etc/default/vxsf. This tunable is system-wide and persistent, so it only needs
to be set once per server. The SmartMove feature is turned off by default.
The SmartMove feature takes effect when a plex is attached or reattached using
the vxplex, vxsd, or vxassist commands.
