Luscious Lebkuchen: XtreemFS 1.2 now available

XtreemFS 1.2 ("Luscious Lebkuchen") is now available at http://www.xtreemfs.org.

New features:

• asynchronous MRC database backups (database dumps are created in the background)
• new GRID SSL mode: SSL is used for authentication only, data is transferred via plain TCP for a better performance
• Vivaldi-based replica selection and placement
• MRC and OSD wait and retry for a configurable time span if they cannot reach the DIR on startup
• faster file copying of files with 'cp' (by providing correct values for 'st_blksize' with 'getattr')
• additional binaries with standard Unix names (mount.xtreemfs, mkfs.xtreemfs, lsfs.xtreemfs, rmfs.xtreemfs)
• experimental Hadoop file system driver for XtreemFS
• web-based admin console
  

We also fixed most of the bugs recorded in the tracker.

When upgrading your XtreemFS installation from 1.1 to 1.2, MRC and DIR databases should be converted automatically, without the need for human intervention. However, for safety reasons, we suggest to create an XML dump with the old release before updating; see "Updating" section in the XtreemFS FAQs (http://www.xtreemfs.org/faq.php).
