Hello Justin,
I am not sure NFS is a good option here as I see no way how the locking
and concurrent access is working from several nodes to single file
system location.
I was always skeptical about sharing NFS resources for multiple nodes to
write/read, unless a locking is implemented (e.g. like Apache Lucene does).
Or I am missing here something and there is no concurrent access to
these resources?
Thank you in advance!
Kind regards
Sergiy

It could be an instance of LocalFileSystem, if the file system pointed to
was shared by, for example, NFS or CIFS.
But DbFileSystem is another way to do that.

Hello Etile,
if I correctly understood the discussion and explanations in this
thread, the repository-level file system should be shared in cluster,
meaning it cannot be an instance of LocalFileSystem like in your case.
It should rather be DbFileSystem.
Am I right?
Kind regards

Hi there,
just want to thank Thomas and Justin for their worthful hints. I
managed to
get the jackrabbit cluster up and running with PostgreSQL. Please find
my
repository.xml below this text. Do you want me to attach it to the
corresponding wiki page? It think that it might serve as a good example
for
anyone who wants to use clustering with PostgreSQL.

Hi,
Could you, please, give me some hints if there are any advantages in
using
DatabaseFileSystem compared to LocalFileSystem?
Yes, in my view LocalFileSystem is appropriate. Only config files are
stored in the FileSystem, no user data. LocalFileSystem is easier to
use and configure. Some people may want to avoid creating files in the
file system, so they can use a database FileSystem.
I assume, the information about clustering configuration
(http://wiki.apache.org/jackrabbit/Clustering ) is also valid for
Jackarabbit 2.1.x/2.2.x. Is it correct?
Yes.
Regards,
Thomas
