Multiple RADOS monitor IPs to add RBD Primary Storage
Hi There,
I am using ACSv4.17
I added my primary storage using a single mon IP to attach the RBD pool. My
questions are following.
1. How to add multiple RADOS monitor IPs to add RBD Primary Storage?
2. Is there any way to add multiple RADOS monitor IPs to Existingly added
RBD Primary Storage which was a single RADOS monitor IP?
Yours sincerely,

You really want Round Robin DNS. Especially with the 'new' cephadm
Monitors can be spawned dynamically by the Ceph cluster and thus the IP
of a monitor can change rather quickly.
So with DNS you have the right control.
And everything starts with DNS. You'll need working DNS anyway :-)

The last time i've looked up this issue, it was proposed to use
DNS round-robin, aka add every monitor-IP as A-Record to your monitor-
alias and refer to it by name.
Not, that I like that solution, since it adds up another dependency to
DNS, but that's how we run it since a few years ;)
And no, AFAIK multiple IP's are not supported.

I suggest you create a Round Robin DNS record which contains the IPs of
all the Ceph Monitors. You use that hostname and then you can modify the
IPs afterwards when needed.
