Re: [PATCH] mkcephfs: Don't transfer absolute path of mkcephfs to other hosts.

2013-11-05 Thread Yunchuan Wen
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.
