    The recommended approach for sharing directories between servers is:

    1. Set up a central network attached storage server.
    2. Create a directory structure on the storage server that mirrors the directories listed in the table above.
    3. Replace the above directories on each server with links to the corresponding directory on the network attached storage server.

    I have setup a NAS storage and granted READ write for the nodes in the load balance setup.

    Do you know how to properly implement step 3. above? are you mapping each folder directly or using a symbolic link?

    Share the following directories across all servers:

    • APPIAN_HOME/_admin/accdocs1/
    • APPIAN_HOME/_admin/accdocs2/
    • APPIAN_HOME/_admin/accdocs3/
    • APPIAN_HOME/_admin/mini/
    • APPIAN_HOME/_admin/models/
    • APPIAN_HOME/_admin/plugins/
    • APPIAN_HOME/_admin/process_notes/
    • APPIAN_HOME/_admin/shared/
    • APPIAN_HOME/server/archived-process/
    • APPIAN_HOME/server/channels/gw1/
    • APPIAN_HOME/server/collaboration/gw1/
    • APPIAN_HOME/server/forums/gw1/
    • APPIAN_HOME/server/msg/
    • APPIAN_HOME/server/notifications/gw1/
    • APPIAN_HOME/server/personalization/gw1/
    • APPIAN_HOME/server/portal/gw1/
    • APPIAN_HOME/server/process/analytics/0000/gw1/
    • APPIAN_HOME/server/process/analytics/0001/gw1/
    • APPIAN_HOME/server/process/analytics/0002/gw1/
    • APPIAN_HOME/server/process/design/gw1/
    • APPIAN_HOME/server/process/exec/00/gw1/
    • APPIAN_HOME/server/process/exec/01/gw1/
    • APPIAN_HOME/server/process/exec/02/gw1/

    A symbolic link should do the job.
