Subject: [pve-devel] ceph create pool with min_size=1 not possible anymore with last gui wizard
Date: Fri, 04 Jun 2021 04:47:55 +0200 [thread overview]
Message-ID: <2422013ee08dd4e3abb04ba5360a084beddf5183.camel@odiso.com> (raw)
Hi,
I was doing a training week with students,
and I see that the new ceph wizard to create pool don't allow to set
min_size=1 anymore.
It's currently displaying a warning "min_size <= size/2 can lead to
data loss, incomplete PGs or unfound objects",
that's ok , but It's also blocking the validation button.
Some users with small cluster/budgets want to do only size=2,
so with min_size=2, the cluster will go read only in case of any osd
down.
It could be great to allow at least min_size=1 when size=2 is used.
also,
Other setup like size=4, min_size=2, also display the warning, but
allow to validate the form.
I'm not sure this warning is correct in this case , as since octopus,
min_size
is auto compute when pool is created, and a simple
ceph osd pool create mypool 128 --size=4 , create a pool with
min_size=2 by default.
