Create the meeting recordings volume

Meeting recordings are stored as MP4 files in a temp directory on the meeting recorder nodes during the meeting. After the meeting, the recordings are moved to a persistent volume. Allocate a volume accessible to the Kubernetes cluster that is substantial enough to handle the expected number of meeting recordings assuming a rate of about 100M per 1 hour of meeting.

By default, recordings persist for three days, so keep that in consideration as well when sizing the volume.

In previous releases of Sametime, only the recordings pod needed to access the persistent volume. In Sametime 12, workloads have moved from virtual or physical machines into Kubernetes pods. There are more than one type of pod that requires access to storage in Sametime 12. Sametime requires an access mode called "read write many" or "RWX" which will allow for more than one node to access the volume at a time.

For additional information on access modes, see the Persistent Volumes topic in the Kubernetes documentation.
