Re: [ClusterLabs] Sync Apache config files

[Victor José Acosta Domínguez]

You have many options to do that:
- lsyncd+csync2/rsync
- cron+rsync
- glusterfs replicated f's

Lsyncd + csync2 is a good option if you need near to real time replication

Cron + rsync is a good option for scheduled replication

Glusterfs is good for real time replication
For 2+ nodes

Regards

It depends on how much data there is and what the update model is. For
larger datasets zfs incremental snapshots work best IME, although on our
two-node active/passive pairs I haven't had any problems with DRBD
either -- as long as it's not exported via nfs on centos
7/corosync/pacemaker.

Hmm, Puppet is also a good idea. Thanks.

I haven’t tried because we have not so many Linux servers. Just a handful.

Short beginner answer: yes.

No.

There's any number of ways to do it but pcs is not one of them.
Automation solutions like chef or puppet can do it (saltstack has an
event-reactor system that can make it transparent, don't know about
others), you could put it on zfs and clone snapshots, syncthing, rsync,
and so on.

Hi,

As far as I know pcsd has no such functionality.
This is possible using Cluster Sync tool csync2 
http://oss.linbit.com/csync2/.

Can pcsd do this?
