[Gluster-users] failed to create directories

[Mingfan Lu]

Hi,

I failed to create directories (using python os.makedirs) occationally, the
following is an example.

When 00:01:56， my application try to create the directories
/mnt/upload/sh_ugc/production/video/2014/01/22/a38/466/351/ ,but finally,
my application failed write the file to the directories. I use ls to find
that the directories doesn't exist, that means the application failed to
create the directories.

>From the glusterfs client's log, I found those pasted below, I could not
understand why? any could help to figure out the root cause? thanks
