hi Vijai,
        I am not sure if you are maintaining this now, but git blame
gives your name, so sending the mail to you. Could you please take a
look at
http://build.gluster.org/job/rackspace-regression-2GB-triggered/8148/consoleFull
where the failure happened. If someone else is looking into this, please
add him/her to the thread.

Hi Pranith,

I will have a look at this testcase failure.
I think even Atin had faced issue with
this. I am not sure if he has solved it.


Quick update on this :

Looking at the log I found this error

snap4-ba05b929-8cb3-4bf2-811f-1b31b1fb881f.log:[2015-05-04 05:17:24.192063] E

0-rpc_transport: invalid argument: this


__svs_initialize_snapshot_volume failed because of failure of glfs_init.
With the available information, I am not sure why glfs_init failed.
I am trying to find the root cause for this. I have executed this more
than 20 times in my system, and It did not fail even once :-/

If any of you have encountered issue similar to this, your help
is much appreciated.


I have seen the second error line in gfapi logs while running sample gfapi programs. I think, it is being logged during the invocation of glfs_fini(). But here, even glfs_init() failed which was not the case for me. Note that this "invalid argument: this" error is seen in logs even after successful run of a gfapi program.
