Release Notes: This release adds an automatic replica creation feature (replica_check), an IO statistics monitoring feature (config-gfmd-iostat, config-gfsd-iostat), a ganglia plugin, and improvements to tools to maintain replica location (gfncopy, gfprep, gfpcopy, etc). Stability under high load conditions is improved, as well. gfarm2fs 1.2.9, gfarm samba plugin 1.0.0, and gfarm zabbix plugin 1.1.0 are also released.
Release Notes: This release adds gfs_seekdir() and gfs_telldir() APIs, which are needed by the newest gfarm-samba plugin, and fixes many problems regarding the hot standby metadata server. It is strongly recommended to upgrade to this version.
Release Notes: This release fixes a serious problem at gfmd startup. All users of version 2.5.2 are strongly encouraged to upgrade. This release also includes performance improvements for GSI authentication and some other bugfixes. gfarm2fs 1.2.6 is also released, with a fix for a bug with the Gfarm ACL feature. A new package, Gfarm/MPI-IO plugin version 0.0.1, is introduced. This is a ROMIO ADIO for the Gfarm file system, which improves the N-to-1 parallel I/O performance in MPICH2.
Release Notes: This release adds an audit log feature of file creation/modification/removal, and includes several bugfixes for the feature to support replicated metadata servers. Upgrading is recommended, especially for 2.5.0 and 2.5.1 users. gfarm2fs-1.5.2 is also released with a bugfix in symbolic link handling.
Release Notes: This release includes bugfixes for replicated metadata servers. Upgrading is recommended. Gfarm and gfarm2fs now work on MacOS X.
Release Notes: This release supports master-slave synchronous and asynchronous replicated metadata servers for immediate failover of a metadata server and disaster recovery. Synchronous replication ensures to transfer metadata updates to slave servers, which enables immediate metadata server failover without any loss of metadata updates. Asynchronous replication does not ensure it, but it is used for disaster recovery to set up slave metadata servers in distant locations. This release also includes many updates and some bug fixes.
Release Notes: This release newly supports extended access control lists and federation of Gfarm file systems by using Gfarm URL symbolic links. Several bugs were fixed, and several performance improvements were made.
Release Notes: This version adds several new features like automatic replication, extended attribute caching, known_network directive to specify the network structure of data nodes, among several bug fixes and performance improvements.
