The documentation for “Front-end HA Setup” says this about shared data on the nodes:
Shared data between HA nodes
HA deployment requires the filesystem view of most datastores (by default in
/var/lib/one/datastores/) to be same on all front-ends. It is necessary to setup a shared filesystem over the datastore directories. This document does not cover configuration and deployment of the shared filesystem; it is left completely up to the cloud administrator.
What is the recommended implementation for a shared files system here? NFS share, DRDB, rsync, etc?
Any best practice advice would be highly appreciated!
