Ceph on a single host makes little to no sense. You're better of running

I'm not aware of any directly, but I know rook-ceph is used on Kubernetes, and
Kubernetes is sometimes deployed with BGP based SDN layers. So there may be a
few deployments that do it that way.

Hi,
I created a Ceph environment with 3 filesystems in the pacific version,
but I'm facing a problem. I set filesystem size but it's not changed.
When I mount different filesystems on a client, they all get the same
size. Even though I put different values.
I've already tried

Oh, I just read your message again, and I see that I didn't answer your
question. :D I admit I don't know how MAX AVAIL is calculated, and whether
it takes things like imbalance into account (it might).

Hey Wladimir,
That output looks like it's from Nautilus or later. My understanding is
that the USED column is in raw bytes, whereas STORED is "user" bytes. If
you're using EC 2:1 for all of those pools, I would expect USED to be at
least 1.5x STORED, which looks to be the case for jerasure21.
Hi Jay,
looks like there is a bug in the code - no proper handling for this
config parameter. Ticket created: https://tracker.ceph.com/issues/51540
Thanks,

I'm having the same problem, the setting doesn't affect the warning at all.
I'm currently muting the warning every week or so (because it doesn't

It does. It’s calculated relative to the most-full OSD in the pool, and the
full_ratio
I have a pretty firm grasp on how OSD encryption with LUKS works, but I'm wondering if anyone has found a way to avoid storing the lockbox keyring on disk?

Sorry, I did not use it before, we evaluated it and went for L2 below ToR.
You need to design the BGP network with your network team because
every node will have an ASN too.
You need to set up a test network before going to production.

Without using FRR you are still L2 below ToR. Do you have any
experience with FRR?
You should think about multiple uplinks and how you handle them with FRR.
Other than that, it should work, we have been in production with BGP
above ToR for years without any problem.

Hello Stefan, thanks a lot for the reply.
We have everything in the same datacenter, and the fault domains are per
rack. Regarding BGP, the idea of the networking team is to stop using layer
2+3 and move everything to full layer 3, for this they want to implement
BGP and the idea is that each

Out of curiosity, is there someone here that has his Ceph cluster running
with BGP in production?
