We have a HA setup with shared storage on a NFSv4 share. During the startup
of the second server I got the following Exception and the startup process
will be stopped:
17:32:12,900 INFO [org.apache.activemq.artemis.integration.bootstrap]
AMQ101000: Starting ActiveMQ Artemis Server

I can reproduce the behaviour when I try to cat the file from the console:
[foo@broker bin]$ cat /data/artemis_shared_store/journal/server.lock
cat: /data/artemis_shared_store/journal/server.lock: Input/output error
Used environment: RHEL 7.3, Artemis 2.4.0
Btw: I tried ASYNCIO and NIO and got the same results.
Btw2: The same NFSv4 share works perfectly fine for a HA setup with two
embedded Artemis instances in JBoss EAP 7.0 (Artemis 1.1.0.SP16-redhat-1).
In my understanding NFSv4 is not recommended due to performance issues but
should work without errors?
