Hello,
as i understand v3 no longer supports using symlinks in the media library. Could someone please expand on how i could possibly using bind points to implement a shared media library across multiple streams? I can set up a bind and mount it to one stream no problem, however i seem unable to then bind the same directory to another stream in order for both streams to use the shared media folder? Any help would be great.
thanks,
gavin

the procedure is detailed under the "Client Data (Linux)" section here:
http://www.centova.com/doc/cast/internals/files
The article explains how to setup a bind mount for the entire /vhosts/ directory (so for all your users), so if you want to create it for a single user, you should replace /usr/local/centovacast/var/vhosts with /usr/local/centovacast/var/vhosts/USERNAME (replace USERNAME with the actual user's account name)

What impact would running this change have on a running server (e.g: would the streams need to be restarted, etc)?
Thanks.

Thanks.
That is just an example, the article mentioned by Alexiu explains how to add this mounts to fstab so that they'll be re-mounted in case of a server reboot.
-
I realise that but is adding the new mounts transparent to Centova or does the webserver need restarting, etc?

Mounts occur at a kernel level, so yes they are transparent for any application. It will be as if you just moved some files there.
