Khoi Pham updated NIFI-6965:
----------------------------
    Description: Hello, it seems to me that NiFi root process group is saved in 
memory only. I attached a persistent volume to NIFI_HOME folder and yet 
whenever pod restart a new root process group is created and all my previous 
works disappear. I did not change any default settings except 
`NIFI_WEB_HTTP_HOST=0.0.0.0`. Any idea?  (was: Hello, it seems to me that NiFi
