There will be pending heals only when the brick process goes down
or there is a disconnect between the client and that brick. When
you say " gluster process is down but bricks running", I'm
guessing you killed only glusterd and not the glusterfsd brick
process. That won't cause any pending heals. If there is something
to be healed, `gluster volume heal $volname info` will display the
list of files.
Hope that helps,
Ravi

Thanks Karthik / Ravishankar in advance!

Hi all,
I need someone to explain if my gluster behaviour is
correct. I am not sure if my gluster works as it
should. I have simple Replica 3 - Number of Bricks: 1
x 3 = 3.
When one of my hypervisor is disconnected as peer,
i.e. gluster process is down but bricks running, other
two healthy nodes start signalling that they lost one
peer. This is correct.
Next, I restart gluster process on node where gluster
process failed and I thought It should trigger healing
of files on failed node but nothing is happening.
I run VMs disks on this gluster volume. No healing is
triggered after gluster restart, remaining two nodes
get peer back after restart of gluster and everything
is running without down time.
Even VMs that are running on “failed” node where
gluster process was down (bricks were up) are running
without down time.
I assume your VMs use gluster as
the storage. In that case, the
gluster volume might be mounted on
all the hypervisors.
The mount/ client is smart enough
to give the correct data from the
other two machines which were
always up.
This is the reason things are
working fine.
Gluster should heal the brick.
Adding people how can help you
better with the heal part.
@Karthik Subrahmanya @Ravishankar
N do take a look and answer this part.
Is this behaviour correct? I mean No healing is
triggered after peer is reconnected back and VMs.
Thanks for explanation.
BR!
Martin
