Hi all!
  
     now my ceph version is 0.62! yesday I update it from 0.56.3!
     
     I found  the init-ceph scrip in defferent ceph version has lots devfrents!

    my ceph version is 0.62! what make me confuse is that I can not use the init-ceph,  which version is 0.62 ,  start my cluster. when I can user the init-ceph , which version is 0.52.3, start my cluster!  what is more !  the 0.62 vesion's init-ceph can break my osd map!  I should rebuild the cluter use the mkcephfs! when I run ceph osd tree , the result is break!

    by the way!  I found that  if I would not clearn the /run/ceph/    , there will some wrong can not let cluster run well!
    so , if I want to rebuilt the ceph cluster!
       # umont /data/osd.id
       # rm -rf /data/*
       #rm -rf /run/ceph/*
   
 Any pointers would be appreciated!

thinks!
peng
