What is Ceph: https://ceph.io/en/discover/
A
All
right,
so
the
one
thing
I
had
in
here
was
the
host
maintenance.
First
thing
I
think
we
had
talked
about
this
before,
but
basically
the
idea
is
that,
right
now
the
force
flag
on
host
maintenance
enter
all
it
does
is
Force
to
the
okay
to
stop
functions
that
are
beneath
it,
but
if
those
still
fail
with
the
okay
to
stop
which
they
do
a
decent
amount
of
the
time,
there's
a
lot
of
conditions
where
they'll
still
fail.
A
You
can't
actually
put
the
hose
in
the
maintenance
mode,
so
there
have
been
some
asks
to
have
a
way
to
like
properly
force.
It
I
was
always
finally
looking
into
that
now,
but
I
think
we
talked
about
it
before,
but
obviously
we
don't
have
the
2022
notes
anymore.
So
I
didn't
remember
what
we
said
about
that
I
brought
up
again
here.
A
What
I
kind
of
wanted
to
do
was
have
something
like
get
okay
to
stop
or
something
flag
that
actually
will
just
I,
don't
know
put
in
the
maintenance
mode
on
its
own
I.
Don't
know
if
you
want
extra
warnings
for
that
or
whatever
so
I've
had
to
bring
up
here.
Keep
someone
on
the
April
news
about
that
I!
Don't
have.
A
The
idea
is
like,
if
you're
going
to
do
some
I,
don't
know
work
on
the
infrastructure
that
node
or
whatever
you
don't
want
the
actual
steps
off
running
as
you
do
it.
So
we
want
it
to
sort
of
nicely
top
it
all
beforehand
and
you
can
bring
it
back
out
later.
I
said:
if
there's
some
reason,
the
okay
itself
doesn't
pass
for
whatever
reason
like
say:
there's
the
size
of
the
the
pgs
will
be
degraded.
If
you
stop
all
the
osds
on
this
host
or
something
like
that,
it
just
won't.
A
Let
you
do
it
because
if
you
pass
the
force
plug
I,
think
so,
for
people
who
are
like
I
really
do
need
to
top
of
the
demons
in
the
show
to
have
to
do
some,
some
maintenance
on
this
node,
no
matter
what,
even
if
the
stuff
says
that
it's
ipgs
will
be
degraded
or
everything
won't
work.
A
They
can't
basically
like
it
won't.
Let
you
do
that.
So
some
people
have
asked
for
the
ability
to
do
that.
A
So
it's
not
as
Extreme
as
draining
because
we're
not
removing
anything
we're
just
stopping
but
definitely
means
that
for
the
time
being,
they're
not
they
can't
participate
in
the
cluster
like
any
of
the
osds
or
the
monitors
and
stuff
won't
be
doing
anything.
A
Do
you
want
to
be
a
bit
careful
with
it,
which
is
why
I
think
it
was
so
I,
don't
know
careful
before
we're
like
even
with
the
force
flag,
it
wouldn't
do
very
much.
They
obviously
would
you
know
just
pass
it
to
the
underlying
okay
to
stop
functions,
and
it
would
still
not
put
it
in
maintenance
mode
if
those
failed
with
the
force
flag
provided,
but
some
people
wanted
a
little
bit
more,
forcing
so
I
think
I
was
I
was
willing
to
put
something
in
that
like
like
totally
skip
that
check.
A
If
you
really
need
it
like
for
drain,
it's
a
bit
more
extreme
because
we're
just
fun
removing
things,
but
for
this,
when
you
think,
like
the
node
in
theory,
should
come
back
later,
a
lot
of
people
like
us
just
sort
of
work
around
maybe
could
be
good.
A
A
I,
don't
know
what
was
anything
so
anyway,
I
guess,
I
brought
it
up
to
ask
people.
Think
it's
the
okay.
C
C
So
I
I
should
have
name
in
chat.
I
think
that
if
it's
potentially
risky
we
should
have
a
scary
on-purpose
knit
flag
like
like
I
said
emergency
or
you
know
you
might
you
might
trash
your
whole
cluster?
If
you
do
this
as
something
neutral
like
skip
okay
to
stop
I,
if
I
didn't
intimately,
if
I
didn't
hear
you
just
say
all
the
things
you
said,
I
would
have
no
idea
what
that
means.
A
Yeah
yeah,
it's
more
basically,
this
guy's
what
it's
actually
doing
behind
the
scenes,
but
I,
don't
that's
what
is
concerned
too.
Is
it's
not
actually
useful
to
anyone
outside
they
don't
know
what
that
is
so
yours,
I
guess,
is
it
better
would
show
how
extreme
I
guess?
What
you're
doing
is
that
we're
not
going
to
check
if
it's
okay
to
stop
these
demons,
we're
just
going
to
stop
them
better
run.
A
C
A
This
is
sort
of
what
this
sort
of
is
either
like
I'm,
never
going
to
have
this
Nokia
stops,
but
so
just
let
me
do
this
or
like
I,
really
need
to
do
this.
So
if
all
the
checks-
just
let
me
put
this
in
latest.
C
C
A
Yeah,
remember
you
just
ask
a
second
ago.
A
B
A
It
was
pretty
much
force
in
what
you
asked
about.
I
was
going
to
say
yes
combined
it
with
the
force
flag,
because
that's
what
we've
done
everywhere
else
as
far
as
I
know,
whatever
it's
Force,
plus
this
thing
or
whatever
you
need
a
more
extreme
flag
than
Force.
Usually
you
pass
it
with
force
or
if
they
don't
pass
Force
instead
of
doing
anything,
you
tell
them,
they
have
to
password
force
and
usually
gives
like
an
extra
warning,
like
we
say
like
like
Warning.
By
the
way,
this
will
do
X
cool.
B
No
you're,
okay,
so
in
this
case
we
don't
plan
to
reschedule
the
daemons,
though
right
we
want
them
still
intact
on
that
host.
No.
A
We
definitely
don't
want
to
do
that
for
maintenance
mode,
because,
again,
I
think
the
idea
is
they'll
come
back
and
if
people
really
want
them
on
somewhere
else,
so
they
can,
they
can
sort
of
make
that
happen.
They'd
like
at
least
temporarily
and
move
them
back,
and
we
also
I,
don't
I,
don't
I
wasn't
planning
on
doing
any
sort
of
changes
to
the
scheduler
around
this
stuff.
A
The
reason
for
that
is
that
people
might
want
a
situation
where
like
to
stop
this
for
a
while,
but
don't
put
it
like
somewhere
else
that
if
you
ever
want
to
put
it
somewhere
else,
you
can
do
that
on
your
own,
like
that's,
not
that's,
always
possible
to
do
even
mattify
the
placement
in
some
way
that
works
right
and
put
it
back
after,
but
I
think
this
is
just
for
like
I
want
to
just
have
this
like
this
for
like
a
few
hours
while
I
do
something
and
then
I'll
put
it
back
later,
I
don't
need
to
bother
moving
stuff
around.
A
What
maintenance
mode
does
in
general?
It's
it's
stop,
but
not
removed,
because
we
have
the
drain
for
removing
and
then
maintenance
mode
for
stopping.
A
B
I
guess,
as
an
alternative,
we
could
use
the
yes
I
really
mean
it
flag,
but
just
utilized
all
over
the
place
in
the
CLA.
A
I
thought
about
that
one,
because
that
is
sort
of
the
one
that
Seth
has
used
in
the
past
and
I
guess
people
would
maybe
be
more
familiar
with
it.
I've
always
thought
it
was
just
like
really
long,
I
guess
it's
probably
on
purpose
to
some
degree.
C
That's
my
only
so
that's
my
why
I
would
slightly
suggest
a
new
flag.
A
I
mean
I,
don't
remember
all
the
uses
of
gifts,
I
really
really
mean
it.
What
exactly
it
does
I
mean
I,
always
thought
it
as
sort
of
doing
what
this
is,
which
is
like
we're
just
going
to
skip
safety
checks
entirely
and
do
whatever
you
tell
me
to
do.
B
A
I
know
for
to
me:
I
thought:
the
meeting
was
actually
pretty
similar
here
with
the
other
ones.
I
thought
I
was
going
to
voice
because
I
always
thought
the
Vlog
was
really
long,
but
I.
Guess
again,
that
is
sort
of
the
point
is:
if
you
really
want
to
do
it,
you
have
to
type
out
this
long
flag,
another
little
extra
layer,
protection,
really
antioxidant
or
something.
A
Yeah,
that
was
all
we
had
about
this,
though
I
think
it'll
I
want
to
implement
in
general
I.
Don't
think
anyone
has
any
problem
with
the
idea
of
this
could
exist
in
case
there
are
some
cases
where
you're,
not
accounting,
for
or
because
we
are
thinking
of
even
that
you
might
really
want
to
force
this
there's
more
just
what
do
you
want
to
call
it.
A
A
Yeah
I
know
at
least
I
remember.
We
have
a
message
like
that
for
training
hosts
where,
if
at
least
it's
around
like
the
offline
and
the
fourth
stuff,
I
think
where,
if
like
you
try
to
like,
create
an
offline
host.
Well,
like
a
message
saying
like
we
can't
do
that,
like
you
can
pass
the
offline
flag
and
then,
if
you
pass
just
stop
flat,
I
think
you
have
to
also
pass
a
force.
What
gives
you
a
message
like
I,
don't
know,
make
sure
you
also
pass
force
or
after
do
that
either.
A
Oh
yeah,
so
I
went
for
the
the
last
admin
label
host,
which
is
again
something
that
could
be
dangerous.
Removing
the
last
admin
label
hosts.
If
you
don't
pass
Force
when
you
do
that
it
runs
it
prints.
This
long
message
telling
you
like
what
you're
risking
by
doing
this,
and
then
it
tells
you
you
can
pass
Force.
You
really
need
to
I
guess
we
want
something
like
that
here.
A
Okay,
so
right
now
all
we
have,
for
it
is
with
the
force
flag.
If
something
fails,
it
either
comes
up
as
like
a
warning
or
something
else,
the
other
one
is,
and
then
we
have
a
message
where
that
things
that
are
warnings
or
things
that
can
be
passed
with
the
force
flag.
A
So
we
at
least
will
tell
people
if,
like
they
have
conditions
where
just
the
force
flag
will
get
through.
We
tell
them
about
that.
If
there's
some
of
this
is
called
that's
stronger
than
warning
in
here,
maybe
just
I,
don't
know,
then
I
think
we
still
print
that
message,
but
basically
we're
saying
like
you
can
get
around
these
types
of
issues
with
the
forged
flag,
but
the
other
ones
you
can't
and
this
flag
would
now
get
around
to
those
ones
as
well,
because
it
wouldn't
even
run
these
sort
of
checks.
A
A
Yeah,
that's
all
I
had
about
that.
I
thought
there
wasn't
too
much
to
say
about
it.
I
was
just
passionate
about
flag
and
they
mean
what
maintenance
mode
does
I
think
we've
sort
of
covered
now.
A
That's
kind
of
all
I
had
this
week.
Actually
anybody
have
any
other
topics.
I
want
to
talk
about
in
here.
