Hi - have just recently completed the Elasticsearch to OpenSearch migration (as per OpenSearch migration instructions.

But experiencing issues with starting the opensearch service via
“systemctl start opensearch.service” - note starts via a manual call to “/usr/shared/opensearch/bin/opensearch -d” no issues!

The Error AccessDeniedException: /var/run/opensearch/opensearch.pid

Hey @Steohen

Perhaps try this.

chown -R opensearch:opensearch /var/run/opensearch/opensearch.pid

should look like this;

root@opensearch:/var/log/opensearch# ls -al  /var/run/opensearch/opensearch.pid
-rw-r--r-- 1 opensearch opensearch 4 Nov 28 23:56 /var/run/opensearch/opensearch.pid
