NFS Directories between 2 Servers I have 2 parallel Drupal Web Servers running (serving for one Drupal Instance together) and now i need to install NFS. My experience in multi Drupal Servers is, each Drupal Instance (Server) uses their own Aggregated JS + CSS files (storing in: sites/default/files/js and sites/default/files/css folders) which can NOT be used as common. (Files can not be the same for both Servers. They use their own ones.)

Based on these issues, my questions are:


How NFS actually works between Multi Drupal Servers?
Which directories will be/need to be shared between?
What will happen to Aggregated Files?
What will happen to Web User Uploads paths and files? (Need any configuration in Drupal?)


Can anyone share these knowledge/experience please?
To prevent synchronization issues, you should mount the files directory as a shared folder over NFS between the drupal webservers, so that each Drupal instance has a symlink to the same file share

e.g:

/var/www/drupal-site-mysite/sites/default/files -&gt; /var/lib/sitedata/drupal-site-mysite/files

where /var/lib/sitedata/drupal-site-mysite/files is a NFS mount/share.
