[wp-hackers] Load Balancing | Media Uploads to Multiple Servers

Actually, I think (and I'm not the sysadmin but the developer) our rsync set
up functions differently than what was communicated earlier (previous
intention was to paint a picture of the benifits of rsync, but since it
seems we all know that now, I can probably explain further). The description
below "should" help paint a clear (or atleast better) picture.
Right now we have a 2-Way sync set up.
1) Common Sync dir (On Disk Copy)
on our Admin box a symbolic link will be created from the "upload dir" to
the sync-uploads dir. All uploaded content will live in sync-uploads and
will sync (single RSYNC) to the NFS mount.
becomes a symbolic link
ln -s /....../sync-uploads/sitename/wp-content/uploads/ uploads
2) NFS Mount - /../sitesync
/../sitesync and /....../sync-uploads are a mirror of each other the NFS
mount allows all files to be pulled and pushed across multiple nodes. The
Actual content is served off the local sync-uploads copy.
Hope this helps stir on some ideas.
