Subject Re: Exception while creating workspace created on another cluster node
Date Thu, 19 Mar 2009 12:51:51 GMT
Hi,

Most likely the problem is that both cluster nodes point to the same
file system. I have updated the documentation at
http://wiki.apache.org/jackrabbit/Clustering

"Clustering in Jackrabbit works as follows: content is shared between
all cluster nodes. That means all Jackrabbit cluster nodes need access
to the SAME persistent storage (persistence manager and data store).
However, each cluster node needs its own (private) FileSystem and
search index. "

Regards,
Thomas
