Hi Jianpeng,
I think this patch will work in the situation that 'mkcephfs' has
been added to the $PATH of other hosts, but what about that 'mkcephfs'
have been deployed to the same path in all cluster nodes, but NOT
added to $PATH, then the original version will work, but now it not
gotta work.
So my suggestion is, first check if the path $0 is valid or not on
other hosts by using something like ' if [ -f $0 ]', if so, just go as
now it is. Otherwise, remove other name components of the path, and
try to use it.
