[gfarm-announce:85355] Gfarm version 2.3.1 released

[Osamu Tatebe <tatebe@xxxxxxxxxxxxxxxx>]

Hi all,

We are pleased to announce the release of Gfarm file system version
2.3.1, and Gfarm2fs version 1.2.0.

		http://sourceforge.net/projects/gfarm/

Major update includes quota, more rich replica management command,
and automatic replica creation option for gfarm2fs.  This release
also includes many updates and some bug fixes.

To enable quota, it is necessary to update the backend database
setting as follows;

# service gfmd stop
# config-gfarm-update --update
# service gfmd start

In this version, the quota is supported only by the PostgreSQL
backend.  If you specified the --prefix option when configuring
the Gfarm file system by config-gfarm, the --prefix option is
required for config-gfarm-update.

Also note that it is necessary to restart gfmd and gfsd (several
times for safe) after upgrading. It is *not* necessary to execute
config-gfarm or config-gfsd script again.
