Hi, I want to do full elk stack upgrade from 6.6.2 to 7.6.2. Started with elasticsearch. I did snapshot backup. Followed this guide [https://www.elastic.co/guide/en/elasticsearch/reference/7.6/restart-upgrade.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.6/restart-upgrade.html) Downloaded package using: `wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.6.2-x86_64.rpm` Installed using: `yum localinstall "package"` Then when I want to start elastic using: **service elasticsearch start** it gives me error: ``` May 5 18:15:43 prd systemd: Starting Elasticsearch... May 5 18:15:44 prd elasticsearch: OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release. May 5 18:15:44 prd elasticsearch: OpenJDK 64-Bit Server VM warning: UseAVX=2 is not supported on this CPU, setting it to UseAVX=1 May 5 18:15:45 prd elasticsearch: ERROR: Temporary file directory [${ES_TMPDIR}] does not exist or is not accessible May 5 18:15:45 prd systemd: elasticsearch.service: main process exited, code=exited, status=78/n/a May 5 18:15:45 prd systemd: Failed to start Elasticsearch. May 5 18:15:45 prd systemd: Unit elasticsearch.service entered failed state. May 5 18:15:45 prd systemd: elasticsearch.service failed. ``` Please can you help me? ---

You can give this a try and see if that works.. `sudo mkdir /usr/share/elasticsearch/tmp && sudo chmod 777 -R /usr/share/elasticsearch/tmp` ---
