Gfarm 2.7.1 released

Hi all,

We are pleased to announce the release of

* Gfarm file system version 2.7.1
* Gfarm file system version 2.6.16
* Gfarm Zabbix plugin version 4.0.0

This Gfarm release includes destination schedule update of gfpcopy to
exclude busy hosts, and other useful updates and bug fixes.

Gfarm Zabbix plugin fixes issues with Template OS Linux, and enhances
the silent data corruption support to alert every checksum mismatch
error without any summarization.

We recommend for all users to upgrade to this version.

Release note for Gfarm 2.7.1 and 2.6.16


Updated feature
* gfpcopy, gfprep – do not copy to busy hosts by default. This will
be disabled by -B option
* gfpcopy, gfprep – -I option to specify interval to collect host
information. Default is 300 seconds.
* gfsd – adjust log level for non-critical replication failure

Bug fix
* incorrect metadb_server_list causes assertion failure
