Resend as I did not reply to the list earlier. TBird responded
to the poster and not the list.

Hi Brett,
Could you please tell us more about the setup?
1 - Gluster v info
2 - gluster v status
3 - gluster v heal <volname> info
These are the very basic information to start with
debugging or suggesting any workaround.
It should always be included when asking such questions
on mailing list so that people can reply sooner.
Note: Please hide IP address/hostname or any other
information you don't want world to see.

Subject: Re: Self Heal Confusion
Still no change in the heals pending. I found this
reference, https://archive.fosdem.org/2017/schedule/event/glusterselinux/attachments/slides/1876/export/events/attachments/glusterselinux/slides/1876/fosdem.pdf,
which mentions the default SELinux context for a brick and
that internal operations such as self-heal, rebalance
should be ignored. but they do not elaborate on what
ignore means - is it just not doing self-heal or something
else.
I did set SELinux to permissive and nothing changed.
I'll try setting the bricks to the context mentioned in
this pdf and see what happens.

Assuming your bricks are up... yes, the

There is/was a bug wherein self-heal would stop
healing but would still be running. I don't know
whether your version is affected, but the remedy is to
just restart the self-heal daemon.
Force start one of the volumes that has heals
pending. The bricks are already running, but it will
cause shd to restart and, assuming this is the
problem, healing should begin...
$ gluster vol start my-pending-heal-vol force
Others could better comment on the status of the
bug.

I
have one volume that has 85 pending entries in healing
and two more
volumes with 58,854 entries in healing pending. These
numbers are from
the volume heal info summary command. They have
stayed constant for two
days now. I've read the gluster docs and many more.
The Gluster docs
just give some commands and non gluster docs basically
repeat that.
Given that it appears no self-healing is going on for
my volume I am
confused as to why.
1. If a self-heal deamon is listed on a host (all of
mine show one with
a volume status command) can I assume it's enabled and
running?
2. I assume the volume that has all the self-heals
pending has some
serious issues even though I can access the files and
directories on
it. If self-heal is running shouldn't the numbers be
decreasing?
It appears to me self-heal is not working properly so
how to I get it to
start working or should I delete the volume and start
over?
I'm running gluster 5.2 on Centos 7 latest and
updated.
Thank you.
