having two systems writing to the same NFS file is very problematic. When I've
done this sort of thing I've had the two copies of rsyslog write to different
directories.

Subject: [rsyslog] rsyslog cluster with NFS backend
Hi.
I have a single rsyslog server (on cloud) receiving logs from a number of
systems (also in cloud). I am planning to add a second server and use NFS cloud
storage as the backend. This storage will be shared across the two syslog
systems.
At the moment, the single rsyslog system receives around 380.000 messages per
minute and stores them on local disk.
The reason for opting NFS shared storage is that logs from systems will be on
one location instead of two. For example, without shared storage and due to
load balancing, Monday logs from serverA can be found in rsyslog1 server and
Tuesday logs for same server can be on rsyslog2 server.
However, I am thinking about the performance of NFS and the (negative) impact
that it could cause on rsyslog. I am concerned about:
* NFS deadlocks
* behaviour when two rsyslog processes write to same file
* encryption and network delay of NFS backend
* rotation of files
Has anyone implemented such rsyslog setup and found it problematic?
Any thoughts/comments for such setup?
Thanks
