Hi ,
We refer to ceph wiki :
http://ceph.newdream.net/wiki/Starting_and_stopping
,use the commands:
start|stop -- start or stop the daemon(s)
forcestop -- force stop (kill -9)
killall -- kill all instance of daemon type on the host (useful is
pid file is wrong or missing)
cleanlogs -- clean out log directory
cleanalllogs -- clean out _everything_ from log directory
If we execute the command : "init-ceph cleanalllogs" , which will
delete / folder (logs,see below ):
================================================

=================================================
Look into init-ceph codes, should be "$log_sym_dir/* " equal to "/*",
"cleanlogs" command also exist this issue. init-ceph script might be add
a check for "$log_dir" and "$log_sym_dir".
and If we detect some of bugs ,does it update to
http://tracker.newdream.net/projects/ceph ?
if yes ,how ?
thanks.
Jeff,wu
