Hi,

"you can choose" ... meaning that it is not mandatory ? and my configuration is correct anyway ?

Because somebody told me that it we put same mcastaddr it is written in corosync documentation (but I can't find where) that corosync may crash if one network becomes unreachable ... could you confirm this or reassure me telling that it is not true ;-) ?

Thanks
Alain

Hi,

corosync-1.4.1-7

with two rings in corosync.conf , and rrp mode active, is it recommended
to have two distinct mcastaddr ?
You can choose to have ether two distinct mcastaddr(eses) or distinct
ports (don't use port +- 1).

(and if so, where can I find this information ?)

It looks like it's not documented (thanks for that information, I will
add to my TODO) and sadly, corosync will not complain (this already
exists in TODO)

Regards,
   Honza

or it is not important and we can have same mcast addr on both rings ?

Saying it in another way , is this sample correct :

      interface {
          ringnumber: 0

          # The following three values need to be set based on your
environment
          bindnetaddr: 182.128.3.0
          mcastaddr: 239.0.0.1
          mcastport: 5405
      }
         interface {
                 ringnumber: 1

                 # The following values need to be set based on your
environment
                 bindnetaddr: 182.128.2.0
                 mcastaddr: 239.0.0.1
                 mcastport: 5405
         }


Thanks
Alain
