volumemount for opensearch logs

[ibrahimjelliti]

Hi, I am trying to ingest opensearch logs to the node for fluentbit as input, I attempt to add extraVolumeMounts:

extraVolumes:
  - name: opensearch-logs
    hostPath:
      path: /var/log/opensearch/logs
      type: ''
extraVolumeMounts: 
  - name: opensearch-logs
    mountPath: /usr/share/opensearch/logs

I upgrade the helm chart with this, I am getting a read-only file system issue with this.
