完全改进：

MooseFS 1.6.27

1.6.27 includes some new features and improvements:

(mfsrestore) fixed bug - freeing filenames memory too early
(all) added initial support for extra attributes (xattr), which will be introduced in upcoming version 1.7
(master+metalogger) better change log synchronization (storage in master memory and sending expected version in metalogger - inspired by Davies Liu)
(master) acceptable difference of percent of hdd usage added to configuration (up to this version this parameter was constantly set to 0.01% - patch contributed by Davies Liu)
(master) added emergency store metadata to some other places on errors during standard hourly store (inspired by Davies Liu)
(cs) default space to be left (256MB) moved to config file (inspired by Davies Liu)
(cs) added extra limits in mfshdd.cfg (minimum space to be left, maximum space to be used)
(cs) fixed charts overflow issue (overflow in net transfer on about 575Mbps and hdd transfer on about 77MBps)
(metalogger) fixed issue: file variable was not clear after close (on rare occasions might cause segfault after disconnecting from master)
(all) cfg files moved form PREFIX/etc/ to PREFIX/etc/mfs/
(cgiserv) improved CGI handle (added support for custom http responses, such as "302 Found")
(master+cgi) showing disconnected chunkservers in "Servers" tab.
(deb+rpm) mfscgiserv moved from mfscgi to separate package, changes in init scripts
(mount) added option 'mfsdelayedinit' - for being run from fstab/init scripts
(master) optimized goal management in chunks
(master) fixed rare race-condition on clear/preserve cache during open in mount
(mount) fixed compiling problems on Mac OS X
(all) changed code to be more compatible with new gcc 4.7 (gcc 4.7 has too strong optimizations - it can generate unpredictable code)
(master) sustain session time could be defined in mfsmaster.cfg
