- From: Osamu Tatebe <tatebe@xxxxxxxxxxxxxxxx>
- Date: Fri, 31 Dec 2010 00:16:46 +0900 (JST)
(BWe are pleased to announce the release of
(B * Gfarm file system version 2.4.1,
(B * Gfarm2fs version 1.2.2,
(B * [NEW] Gfarm Samba plug-in version 0.0.1.
(BThis release supports not only functionalities not supported by the
(Bversion 2.4.0 but also the gfmd-initiated automatic file replica
(Bcreation. The number of file replicas are specified by the extended
(Battribute gfarm.ncopy (of the ancient directory).
(BWhen you would like to create three file replicas for all newly
(Bcreated files, specify three by the extended attribute gfarm.ncopy of
(Bthe / (root) directory as follows,
(B % echo -n 3 | gfxattr -s / gfarm.ncopy
(BThis release also includes many updates and some bug fixes. We
(Bstrongly recommend to upgrade to this version.
(BGfarm Samba plugin enables Windows clients to access the Gfarm file
(Bsystem. So far, it is possible by the samba server and gfarm2fs. The
(Bplugin replaces the gfarm2fs. Note that it is reported that some
(Bfiles cannot be listed in a directory having more than thousands of
(Bfiles. It is experimentally provided for now.
(BRelease note for Gfarm 2.4.1
(B* automatic replication in gfmd [sf.net trac #129]

(BNew configuration in gfmd.conf
(B* no_file_system_node_timeout and gfmd_reconnection_timeout directives
(B to specify the timeout to try to find a file system node and to
(B reconnect to the gfmd, respectively. Default is 30 seconds.
(B* known_network directive to specify a network for file system nodes.
(B File system nodes not specified by the known_network directive are
(B assumed to be in an IPv4 class C network as same as before.
(B* gfmd-initiated file replication [sf.net trac #123]
(B* extended attribute cache in gfmd and libgfarm [sf.net trac #128]
(B* gfmd - check and repair nlinks at start-up [sf.net trac #57]
(B unreferenced inodes moved to /lost+found
(B* gfsd - if the input/output error occurs, kill oneself to cope with
(B the hardware failure [sf.net trac #85]
(B* select a file system node having enough capacity regardless of
(B existent file replicas when a file is overwritten [sf.net #68]
(B* avoid scheduling conflict of file system nodes
(B* try another file replica when the specified physical file does not
(B* gfdf - -P option to specify the metadata server
(B* gfdf - -S and -r options to sort output by available capacity and in
(B reverse order, respectively [sf.net trac #131]
(B* gfdf - -h and -H options to display sizes in human readable format
(B [sf.net trac #126]

(B creation [sf.net trac #169]
(B* fix error handling of protocols in terms of extended attributes in
(B gfmd [sf.net trac #124]
(B* gfmd - plug memory leak in case of authentication error [sf.net trac
(B* gfmd - a file system node temporarily cannot be used if replication
(B error happens due to the connection error to the source target
(B [sf.net trac #162]
(B* Won't compile on FreeBSD 7.3 [sf.net trac #138]
