(BA new stable release of Gfarm 1.4.1 is now available for download.
(BThis version is mainly bugfix release. One major update, however,
(Bis to support a new data schema to reduce data amount in the
(BPostgreSQL server. In the case of that millions numbers of files
(Bare stored on the Gfarm filesystem, the update is critical to the
(Boperation of the metadata server. When you would like to enable
(Bthe update feature on your existing Gfarm environment, you need
(Bto run config-gfarm again as follows.
(B Metadata dump by "gfhost -M" and "gfdump -d"
(B config-gfarm ....
(B Metadata restore by "gfhost -R" and "gfdump -r"
(BWhen you just upgrade the Gfarm from the version 1.4 to 1.4.1
(Bwithout enabling the feature, you don't have to proceed the above
(Bsteps at all.
(BThe software can be downloaded from http://datafarm.apgrid.org/
(BThe bug tracking system is available at http://datafarm.apgrid.org/bugzilla/
(BAs previously announced, the Gfarm source repository is now publicly
(Bavailable to everyone at sourceforge.net to facilitate open source
(Bdevelopment. We are looking forward to your contribution for further
(Bimprovement and enhancement.
