[Gluster-devel] Help needed: NFS Debugging for Glusto tests and Glusto help in general

[Nigel Babu]

Hello,

I've been working on getting the Glusto tests to work and it appears that we're
stuck in a situation which Shewtha and Jonathan haven't been able to fully
arrive at a solution. Here are the two problems:

1. Originally, we ran into issues with NFS with an error that looked like this:

        if 'nfs' in cls.mount_type:
            cmd = "showmount -e localhost"
            _, _, _ = g.run(cls.mnode, cmd)

            cmd = "showmount -e localhost | grep %s" % cls.volname
            ret, _, _ = g.run(cls.mnode, cmd)
>           assert (ret == 0), "Volume %s not exported" % cls.volname
E           AssertionError: Volume testvol_replicated not exported
E           assert 1 == 0

bvt/test_bvt_lite_and_plus.py:88: AssertionError

Today I tried to comment out the NFS bits and run the test again. Here's what
that got me:

        # Setup Volume
        ret = setup_volume(mnode=cls.mnode,
                           all_servers_info=cls.all_servers_info,
                           volume_config=cls.volume, force=True)
>       assert (ret == True), "Setup volume %s failed" % cls.volname
E       AssertionError: Setup volume testvol_distributed-replicated failed
E       assert False == True

2016-11-07 06:20:35,049 ERROR (setup_volume) Number_of_bricks is greater than the unused bricks on servers

Does this make sense to anyone in terms of whether it's an error at Glusto-end
or an error in Gluster that's being caught?
