Mount failed with dynamic provisioned persistent storage glusterfs



Hi,

When trying to provision persistent storage dynamically, below errors was caught,

If I do not use dynamic provision, it works well.

It seemed that above error was thrown by function readGlusterLog().

Is there any solution to work around this issue?

Or Did I miss anything?
