1.6.13版本的安装配置参见
http://www.lsanotes.cn/centos_mfs_1_6_13
升级步骤非常简单官方站也给出了大致步骤
http://www.moosefs.org/mini-howtos.html
1.6.15修复的bugs:
We released a new stable version 1.6.15. This is a maintenance release which includes these changes:
·(daemons) fixed “double free” error
·(metarestore) fixed bugs in “REPAIR” and “SNAPSHOT” entries
·(master) fixed bug in “snapshot” command (“mfsmakesnapshot dir dir/” caused master to hung-up)
·(master) preserving atime and mtime during “snapshot” operation (makes “snapshot” to work more like “cp -Rp” than “cp -R”)
·(cs) ommit “marked for removal” disks during chunk test loop
本文采用的是把现有的Moosefs系统停止后再升级(并且umount client).

五．依次启动所有服务
/usr/local/mfs/sbin/mfsmaster start /usr/local/mfs/sbin/mfscgiserv (cgi 监控可以在浏览器查看) /usr/local/mfs/sbin/mfschunkserver start /usr/local/mfs/sbin/mfsmetalogger start
