[Gluster-devel] ls -l in directory doesn't show file under samba with a brick down

Hi,
Using samba on top of gluster, and when one brick goes down I can't
see files that are actively being made on functional bricks.
Running 2.0.0, I have 2 machines in a NUFA arrangement (log below),
gluster mounted on /mnt, sharing /mnt out from one node via samba. On
the machine that is doing the samba I do a mkdir /mnt/me, then start
copying a big file into /mnt/me. I can do a ls -l /mnt/me and see the
file growing in there. I take down my second node (umount /mnt), back
on the first node everything is fine, the copy continues since the
file is going to a local brick anyway. I can do a ls -l /mnt/me and
see the file growing there fine.
I repeat the above but I'm copying a file into /mnt/me via samba.
When the second node goes down, the copy continues, but I can't see
the file in /mnt/me (a ls -l /mnt/me/nameoffile shows it, but a ls -l
/mnt/me doesn't). If I start a new copy while the second node is
down, then a ls -l /mnt/me shows that file fine. It is only files
that are in the process of being copied while the second node goes
down, and only under samba, that I see the problem.
I thought it might be something to do with samba preallocating the
entire file, then filling it up during the copy. I set 'strict
allocate = yes' in my smb.conf, which doesn't stop the preallocating
but it does make the preallocation real slow, slow enough that i can
watch the file growing and then take the second node down, but then
wham it is then not visible via a ls -l on its directory.
It might not sound like a huge issue, since the copy works. But I am
currently testing our gluster and demonstrating to a user that it will
work OK in the situation when a brick other than actively used one on
the samba server goes down.
Please, any help much appreciated.
Matt
