As gluster cli was failing to create a volume which has tons of brick request in one command. I added this https://review.gluster.org/#/c/18271/5/tests/bugs/cli/bug- 1490853.t test to ensure that gluster is able to parse large request. As per the bug "https://bugzilla.redhat.com/show_bug.cgi?id=1490853";, create was failing, but I added volume start too in the test case whichideally is not required.
I have addressed the same and updated the patch, Thanks Gaurav On Fri, Oct 6, 2017 at 2:31 PM, Michael Scherer <[email protected]> wrote: > Hi, > > so on the last 2 days, I have been contacted by people because some > builders were failling.
