Not repeatable. Once it shows up, it stays there. I sent some other
strange behavior I am seeing to Pranith earlier this evening.

Another issue I am having that might be related is that I cannot
delete some directories. It complains that the directories are not
empty. But when I list them out, there is nothing there.
However, if I know of the name of the directory, I can cd into it and
see the files.

However, from the bricks (see listings below), there are other
directories that are not shown. For example, the References directory
contains the USSOCOM_OPAQUE_ARMOR directory on the brick, but it
doesn't show up on the volume.

The recursive file listed (ls -alR) from each of the bricks shows that
there are files/directories that do not show up on the /homegfs volume.

Subject: Re: missing files
Is the failure repeatable ? with the same directories ?
It's very weird that the directories appear on the volume when you do
an 'ls' on the bricks. Could it be that you only made a single 'ls'
on fuse mount which not showed the directory ? Is it possible that
this 'ls' triggered a self-heal that repaired the problem, whatever
it was, and when you did another 'ls' on the fuse mount after the
'ls' on the bricks, the directories were there ?
The first 'ls' could have healed the files, causing that the
following 'ls' on the bricks showed the files as if nothing were
damaged. If that's the case, it's possible that there were some
disconnections during the copy.
Added Pranith because he knows better replication and self-heal details.

Sorry. Thought about this a little more. I should have been clearer.
The files were on both bricks of the replica, not just one side. So,
both bricks had to have been up... The files/directories just
don't show
up on the mount.
I was reading and saw a related bug
(https://bugzilla.redhat.com/show_bug.cgi?id=1159484). I saw it
suggested to run:
find <mount> -d -exec getfattr -h -n trusted.ec.heal {} \;
This command is specific for a dispersed volume. It won't do anything
(aside from the error you are seeing) on a replicated volume.
I think you are using a replicated volume, right ?
In this case I'm not sure what can be happening. Is your volume a pure
replicated one or a distributed-replicated ? on a pure replicated it
doesn't make sense that some entries do not show in an 'ls' when the
file is in both replicas (at least without any error message in the
logs). On a distributed-replicated it could be caused by some problem
while combining contents of each replica set.
What's the configuration of your volume ?

It sounds to me like the files were only copied to one replica,
werent
there for the initial for the initial ls which triggered a self
heal,
and were there for the last ls because they were healed. Is there
any
chance that one of the replicas was down during the rsync? It could
be that you lost a brick during copy or something like that. To
confirm I would look for disconnects in the brick logs as well as
checking glusterfshd.log to verify the missing files were actually
healed.

I rsync'd 20-TB over to my gluster system and noticed that I had
some directories missing even though the rsync completed
normally.
The rsync logs showed that the missing files were transferred.
I went to the bricks and did an 'ls -al
/data/brick*/homegfs/dir/*' the files were on the bricks.
After I
did this 'ls', the files then showed up on the FUSE mounts.
1) Why are the files hidden on the fuse mount?
2) Why does the ls make them show up on the FUSE mount?
3) How can I prevent this from happening again?
Note, I also mounted the gluster volume using NFS and saw the
same
behavior. The files/directories were not shown until I did the
"ls" on the bricks.
