After adding additional application servers to a high
availability environment, validate each server.
After adding application servers to your high
availability deployment, we recommend verifying that each application
server has the correct configuration.
Verify the shared file system was created and
is owned by demisto user.
sudo ls -lh /<shared>/var/lib/demisto
Modify path as needed if you mounted the shared filed system
at another location.
Confirm you see folders for artifacts, images, systemTools,
etc.
Verify that the
temp
folder on
the new application server contains folders for tempSystemContent,
script directories, etc.
ls -lh /var/lib/demisto/temp
Modify path as needed if you choose a different temp folder
location.
Temp folder must be owned by
demisto:demisto
Validate the
/etc/demisto.conf
files
are the same across all application servers.
Only the
AppID
and
InClusterHostName
keys
should be different per application server.
Log in to the new Cortex XSOAR app server
https://<
app server
>
.
Validate you can view the
Elasticsearch Monitoring
dashboard
from the
Elasticsearch Monitoring
content
pack to check Elasticsearch indexes for shards, replicas, and cluster
status.
Applies only to first application server.
Go to
Settings
Advanced
App Servers
Confirm that two or more application servers are showing
online in the Elasticsearch cluster.
Create a new incident and verify you can view the incident
across all application servers.
