<div>I took down one of the 4 replicate gluster servers for

600GB. Not that much data. After the server comes back online,
it starts auto healing and pretty much all operations on
gluster freeze for many minutes.</div>

<div>During this time, I can see iostat show 100% utilization on
the brick, heal status takes many minutes to return,
glusterfsd uses up tons of CPU (I saw it spike to 600%).
gluster already has massive performance issues for me, but
healing after a 4-hour downtime is on another level of bad
perf.</div>

It is likely that self-heal is causing the CPU spike due to the
flood of lookups/ locks and checksum fops that the self-heal-daemon
sends to the bricks.<br>
There's a script to control shd's cpu usage using cgroups. That
should help in regulating self-heal traffic:
<a class="m_979837676701406854moz-txt-link-freetext" href="https://review.gluster.org/#/c/18404/" target="_blank">https://review.gluster.org/#/<wbr>c/18404/</a> (see
extras/control-cpu-load.sh)<br>
Other self-heal related volume options that you could change are
setting 'cluster.data-self-heal-<wbr>algorithm' to 'full' and
'granular-entry-heal' to 'enable'. `gluster volume set help` should
give you more information about these options.<br>

be disabled for better performance when used just for
file accesses.</div>

Same as you I ran tests on a large volume of
files, finding that main delays are in
attribute calls, ending up with those mount
options to add performance.<br>
</div>
<div>I discovered those options through
basically googling this user list with people
sharing their tests.<br>
</div>
Not sure I would share your optimism, and rather
then going up I downgraded to 3.12 and have no
dir view issue now. Though I had to recreate the
cluster and had to re-add bricks with existing
data.<br>

<div>Can you please explain what

performance issues shown in my
posts?
"negative-timeout=10,attribute<wbr>-timeout=30,fopen-keep-cache,d<wbr>irect-io-mode=enable,fetch-att<wbr>empts=5"
From what I remember,
direct-io-mode=enable didn't make a
difference in my tests, but I
suppose I can try again. The
explanations about direct-io-mode
are quite confusing on the web in
various guides, saying enabling it
could make performance worse in some
situations and better in others due
to OS file cache.</div>
<div><br>
</div>
<div>There are also these gluster
volume settings, adding to the
confusion:</div>
<div>
<div>Option:
performance.strict-o-direct</div>
<div>Default Value: off</div>
<div>Description: This option when

<div>Re: 4.0. I moved to 4.0 after
finding out that it fixes the
disappearing dirs bug related to
cluster.readdir-optimize if you
remember (<a href="http://lists.gluster.org/pipermail/gluster-users/2018-April/033830.html" target="_blank">http://lists.gluster.org/pipe<wbr>rmail/gluster-users/2018-April<wbr>/033830.html</a>).
I was already on 3.13 by then, and
4.0 resolved the issue. It's been
stable for me so far, thankfully.</div>

<div dir="ltr">Hi
again,
<div><br>
</div>
<div>I'd like to
expand on the
performance
issues and
plead for
help. Here's
one case which
shows these
odd hiccups: <a href="https://i.imgur.com/CXBPjTK.gifv" target="_blank">https://i.imgur.com/C<wbr>XBPjTK.gifv</a>.

between copy
operations on
2 servers, I'm
copying a 10GB
dir full of
.apk and image
files.</div>
<div><br>
</div>
<div>On server
"hive" I'm
copying
straight from
the main disk
to an attached
volume block
(xfs). As you
can see, the
transfers are
relatively
speedy and
don't hiccup.</div>
<div>On server
"citadel" I'm
copying the
same set of
data to a
4-replicate
gluster which
uses block
storage as a
brick. As you
can see,
performance is
much worse,
and there are
frequent
pauses for
many seconds
where nothing
seems to be
happening -
just freezes.<br>
</div>
<div><br>
</div>
<div>All 4
servers have
the same
specs, and all
of them have
performance
issues with
gluster and no
such issues
when raw xfs
block storage
is used.</div>
<div><br>
</div>
<div>hive has
long finished
copying the
data, while
citadel is
barely
chugging along
and is
expected to
take probably
half an hour
to an hour. I
have over 1TB
of data to
migrate, at
which point if
we went live,
I'm not even
sure gluster
would be able
to keep up
instead of
bringing the
machines and
services down.</div>

<div dir="ltr">Hi,
<div><br>
</div>
<div>I'm
trying to
squeeze
performance
out of gluster
on 4 80GB RAM
20-CPU
machines where
Gluster runs
on attached
block storage
(Linode) in (4
replicate
bricks), and
so far
everything I
tried results
in sub-optimal
performance.</div>
<div><br>
</div>
<div>There are
many files -
mostly images,
several
million - and
many
operations
take minutes,
copying
multiple files
(even if
they're small)
suddenly
freezes up for
seconds at a
time, then
continues,
iostat
frequently
shows large
r_await and
w_awaits with
100%
utilization
for the
attached block
device, etc.</div>
<div><br>
</div>
<div>But
anyway, there
are many
guides out
there for
small-file
performance
improvements,
but more
explanation is
needed, and I
think more
tweaks should
be possible.<br>
</div>
<div><br>
</div>
<div>My
question today
is
about performance.cache-size.
Is this a size
of cache in
RAM? If so,
how do I view
the current
cache size to
see if it gets
full and I
should
increase its
size? Is it
advisable to
bump it up if
I have many
tens of gigs
of RAM free? </div>
<div><br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>More
generally, in
the last 2
months since I
first started
working with
gluster and
set a
production
system live,
I've been
feeling
frustrated
because
Gluster has a
lot of
poorly-documented
and confusing
options. I
really wish
documentation
could be
improved with
examples and
better
explanations.</div>
<div><br>
</div>
<div>Specifically,
it'd be
absolutely
amazing if the
docs offered a
strategy for
setting each
value and ways
of determining
more optimal
values. For
example,
for performance.cache-size,
if it said
something like
"run command
abc to see
your current
cache size,
and if it's
hurting, up
it, but be
aware that
it's limited
by RAM," it'd
be already a
huge
improvement to
the docs. And
so on with
other options.</div>

gluster team
is quite
helpful on
this mailing
list, but in a
reactive
rather than
proactive way.
Perhaps it's
tunnel vision
once you've
worked on a
project for so
long where
less technical
explanations
and even
proper
documentation
of options
takes a back
seat, but I
encourage you
to be more
proactive
about helping
us understand
and optimize
Gluster.</div>
