Separating eos managers and quarkdb servers

Hello,
Is it supported to run eos managers and quarkdb servers on different machines ?
If yes, what should appear in /etc/xrd.cf.mgm ?:
mgmofs.cfgredishost
Can a DNS alias with round-robin IP addreses be used in:
mgmofs.qdbcluster
and
mq.qdbcluster
Thank you
JM

Hi Jean Michel,

Yes, it is possible, this is how we run at CERN. You need to list all the FQDNs of the hosts where QuarkDB runs since the qclient will fallback or recover any connection errors or to switch to the correct master QuarkDB node using this list.
For example:

mgmofs.qdbcluster  eoshome-ns-i01-00.cern.ch:7777 eoshome-ns-i01-01.cern.ch:7777 eoshome-ns-i01-02.cern.ch:7777
mgmofs.qdbpassword_file  /etc/eos.keytab

Cheers,
Elvin
