[horde] Horde VFS on separate DB machine?

[Kevin Konowalec]

Horde 3.1.5
IMP 4.1.5
PHP 4.4.1
Clustered environment all sharing common NFS space for uploaded files.


I was wondering if it was possible to separate the VFS DB from the  
regular SQL backend?  We're trying to do some testing to see why  
attachments are randomly failing and want to be able to use the  
production database for preferences and address book but want to shift  
the VFS storage to a second non-production database box for test  
purposes.  Is that doable?  If so, how?

We're trying to test if the problem we're having with attachments  
randomly not being sent (though having been successfully uploaded to  
the server) is related to not using VFS at all (simply storing the  
uploaded files on a shared NFS volume).
