I should add, I'm mounting these volumes through GlusterFS FUSE,
not the Samba VFS plugin.<br>

<div>Hello,<br>
<br>
I'm running into some serious problems with Gluster + CTDB
and Samba. What I have:<br>
<br>
</div>
A two node replicated gluster cluster set up to share
volumes using Samba setup according to this guide: <a
moz-do-not-send="true"
href="https://download.gluster.org/pub/gluster/glusterfs/doc/Gluster_CTDB_setup.v1.pdf">https://download.gluster.org/pub/gluster/glusterfs/doc/Gluster_CTDB_setup.v1.pdf</a><br>
<br>
</div>
When we edit or copy files into the volume via SMB (from a
Windows client accessing through a samba file share) this
inevitably leads to a split-brain scenario. For example:<br>
<br>
gluster> volume heal fl-webroot info<br>
