OpenJDK requires procfs

[jarge11]

Installing ELK stack on FreeNAS jail.
Elastic and Kibana work but Logstash will not start because OpenJDK requires /proc/curproc/map to be mounted, but that doesn't happen with a jail.

[2020-07-31T20:37:38,144][ERROR][org.logstash.Logstash ] java.lang.InternalError: errno: 2 error: Unable to open /proc/curproc/map

Looking for advice and suggestions please?

you probably just need to stop the jail, run this command iocage set mount_procfs=1 ${yourLogStashJailNameHere}, and then restart the jail. I had LogStash running in a jail with the property set on the the jail with no issues.

You may also need to iocage set allow_mount_procfs=1 ${yourLogStashJailNameHere} and iocage set allow_mount=1 ${yourLogStashJailNameHere}, and set these sysctl tunables

Code:

security.jail.mount_allowed: 1
security.jail.mount_procfs_allowed: 1
security.jail.param.allow.mount.: 1
security.jail.param.allow.mount.procfs: 1
