13-AUG-2009 version 1.0 release
* read-only replication working
24-AUG-2009
* fcntl lock support (on OSD)
* switched to MRC supplied inode/dev numbers by default
Some applications (e.g. Dovecot) use the inode number to
identify fds pointing to the same file. This does not work
with "local" inode numbers assigned by fuse.
* updated the BabuDB release
fixed a problem with manual checkpoint creation
* hostname used by MRC can be set with hostname property in config file
Necessary if the FQDN is not set/returned correctly on that host.
* OSDs run on Windows
03-SEP-2009
* DIR service uses new on-disk format which is independent of the
protocol version.
* MRC database format changed (USE DUMP/RESTORE WHEN UPDATING FROM 1.0)
compeletely redesigned the policies. There is now only one type of
policies for OSD selection and replica creation/selection
15-SEP-2009
* added on-close replication support
Replicas can now be automatically created when a file is closed
after having been written the first time. This causes the file
to become read-only. The behavior of on-close replication can
be controlled via the xtfs_repl tool.
* fixed SSL problems on Windows
* added support for user authentication based on gridmap files
* improved client performance by eliminating unnecessary system calls
* data cache now uses stripe size instead of system page size
* fixed bugs #38, #41, #42, #43, #45, #49
16-SEP-2009 version 1.1 release
* fixed bugs #51, #52, #53
* added notification mechanism to DIR that sends notification mails to
an admin if an OSD or MRC has failed
26-OCT-2009
* Linux binaries for mounting, creating, removing and listing volumes have
been renamed, in order to be more consistent with Linux conventions
04-NOV-2009
* If an admin password is set, server status pages are now password-protected.
05-NOV-2009
* added GRID SSL mode
When enabled (requires SSL to be enable too), XtreemFS will fall back to
plain TCP after a successful SSL handshake. Enabled in services with
"ssl.grid_ssl=true" in the config file. Client requires certificates
and oncrpcg:// scheme when mounting.
25-NOV-2009
* MRC and OSD wait up to 30s (or as long as defined in startup.wait_for_dir)
for the DIR during start-up.
* added xctl: a script to start and stop the XtreemFS services
* mount.xtreemfs checks for successfull mount before going into background
* fixed the return value for xattr calls which caused problems with the
Mac OS X Finder
27-NOV-2009
* client caches file size updates by default (flushed on close, fsync)
* OSD and MRC status pages can be used to get full stack traces (/strace)
03-DEC-2009
* capability timeout is now a config option for the MRC
(capability_timeout), default is 600s.
* MRC dump/restore are now asynchronous. Backups of the MRC can be done
without interrupting regular operations.
* closest replicas of a file can now be selected based on Vivaldi
coordinates (see User Guide)
* fixed bugs #36, #54, #57, #58, #59, #60, #64, #66, #77, #78, #80, #81,
#82, #83 #96, #97
07-DEC-2009
* java client for XtreemFS (interface is still unstable!) in package org.xtreemfs.common.clients
* experimental hadoop FileSystem driver for XtreemFS (in trunk/contrib/hadoop)
08-DEC-2009
* added web-based admin console (in trunk/contrib/console)
09-DEC-2009
* added per-file block size (st_blksize) to struct Stat;
used by cp to determine I/O buffer sizes on Linux
11-DEC-2009
* version 1.2. release
16-DEC-2009
*fixed issue #109
08-JAN-2010
* status of servers can now be set by admins (online, offline, etc.)
* scrubber now removes dead replicas and creates new ones, marks full replicas as complete if needed
13-JAN-2010
* fixed issues #55 and #75
* added UUID-based OSD selection policy to default policies
22-JAN-2010
* added client support for Fedora 12
9-FEB-2010
* when deciding which OSD to contact to recalculate their position, nodes now choose
more frequently the OSDs that are closer.
21-SEP-2010
* added 'xtfs_acl' tool for getting and setting POSIX ACLs
* added 'chmod' and 'chown' operations to Java MRC client
* updated BabuDB version in MRC/DIR storage backend to 0.4.3
06-JUN-2011
* updated BabuDB version in MRC/DIR storage backend to 0.5.2
* added support for DIR and MRC replication w/ automatic fail-over
