Hi Nigel, As Pranith has already mentioned, we are getting different gfid's in loc and loc->inode. It looks like issue with DHT. If a re validate fails for gfid, a fresh look up should be done.
I don't know if it is related or not but a similar bug was fixed by Pranith https://review.gluster.org/#/c/16986/ Ashish ----- Original Message ----- From: "Pranith Kumar Karampuri" <pkara...@redhat.com> To: "Anoop C S" <anoo...@autistici.org> Cc: "gluster-devel" <gluster-devel@gluster.org> Sent: Thursday, June 29, 2017 7:36:45 PM Subject: Re: [Gluster-devel] Glusto failures with dispersed volumes + Samba On Thu, Jun 29, 2017 at 6:49 PM, Anoop C S < anoo...@autistici.org > wrote: On Thu, 2017-06-29 at 16:35 +0530, Nigel Babu wrote: > Hi Pranith and Xavi, > > We seem to be running into a problem with glusto tests when we try to run > them against dispersed > volumes over a CIFS mount[1].
