The file went into split-brain. I think we should do these tests
with 3.5.2. Where monitoring the heals is easier. Let me also come
up with a document about how to do this testing you are trying to
do.<br>
<br>
Humble/Niels,<br>
Do we have debs available for 3.5.2? In 3.5.1 there was
packaging issue where /usr/bin/glfsheal is not packaged along with
the deb. I think that should be fixed now as well?<br>

Seems like

The problem I
feel is that
whichever
process does
the healing
has the latest
information
about the good
bricks in this
usecase. Since
for VM
usecase,
mounts should
have the
latest
information,
we should let
the mounts do
the healing.
If the mount
accesses the
VM image
either by
someone doing
operations
inside the VM
or explicit
stat on the
file it should
do the
healing.<span><font
