[gfarm-announce:29945] Gfarm version 2.1.0 released

[Osamu Tatebe <tatebe@xxxxxxxxxxxxxxxx>]

Hi all,

We are pleased to announce the release of Gfarm file system version
2.1.0 and Gfarm2fs version 1.0.1.

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

Major update is to support GSI (Grid Security Infrastructure) and some
key features including group management and disk usage report.
Gfarm2fs now supports statfs() which enables 'df' command.

This release includes performance improvement for remote read and
write from a distant location, which may cause poor performance when
accessing to old gfsd in version 2.0.0.  We recommend to upgrade all
file system nodes at the same time although we keep the compatibility.
