Re: [ceph-users] DNS records for ceph

Mons do not communicate with the OSDs on the private subnet. Only OSDs are
on the private subnet.

Re: [ceph-users] DNS records for ceph

Ceph kraken or later can use SRV records to find the mon servers. It works
great and I've found it a bit easier to maintain than the static list in
ceph.conf.

That would presumably be on the private subnet.

I was unsubscribed from the list a while ago because my company was filing
mail as spam and replying to the list about it.  Check for an email like
that.

Re: [ceph-users] DNS records for ceph

[David Turner]

The private network is only used by OSD daemons. The mons, mds, rgw, and
clients do not need access to this subnet. Ceph does not need DNS for
anything.  DNS is very helpful when managing your cluster, so it is helpful
to configure it for the public network.  As nothing talks to the private
subnet, there is no benefit to configuring DNS for it.

[ceph-users] DNS records for ceph

[Anton Dmitriev]

What is the true way of configuring DNS records for ceph?

public network = 10.17.12.0/24
cluster network = 10.17.27.0/24

Storages have separate interfaces for public and cluster networks.

In DNS servers I added records such as storage01 pointing to IPs in 
public network.


Do I need to add extra records which will point to cluster network?

Do I need to add records to /etc/hosts file on storages to make storages 
resolve each other to cluster network addresses?


Or maybe I don`t need to care about cluster network and ceph will 
determine cluster network addresses himself without asking DNS and 
/etc/hosts?


Do monitors interact with OSD using public network?

Do I need to add cluster network to monitors?

[ceph . novice]

I've not received the list mails since weeks. Thought it's my mail provider who 
may filter them out. Have checked with them for days. Due to them all is ok. 

I've then subscribed with my business mail account and do not receive any 
posts/mails from the list.

Any ideas anyone?
