Description of problem:

This test fails more than often, in regression jobs as well in my local setup.

An email https://lists.gluster.org/pipermail/gluster-devel/2018-July/055073.html was sent, but haven't seen any actions.

Comment 2 Nithya Balachandran 2018-08-03 10:51:48 UTC

Not a spurious failure. This is a bug introduced by commit 7131de81f72dda0ef685ed60d0887c6e14289b8c

With the latest master, I created a single brick volume and some files inside it.The first call to ls -l returns Null iatt information. This test uses this information to check if the operation succeeded and hence it fails.

[root@rhgs313-6 ~]# umount -f /mnt/fuse1; mount -t glusterfs -s server1:/vol1 /mnt/fuse1; ls -l /mnt/fuse1/; echo "Trying again"; ls -l /mnt/fuse1

The above works as expected if I revert this commit.

This is fixed as another patch from Mohit. Not seen in a long time.
