Use mount to mount the TREX data directory that you created on the file server onto all TREX hosts. Note the following:
You created the directory mytrexdir on the file server. You mount this directory on all hosts at /mymountpoint/mytrexdir.
This mount point must be the same on all hosts. Otherwise, the system cannot swap from a master server to a backup server. Moreover, the slave servers cannot use a common slave index.
The exact procedure is described in the documentation for your operating system platform.
