Solr cores are not creating

[Christoforos Korifidis]

Hello, I need some help with solr. I followed the instructions "Taking Solr to production" from here
https://solr.apache.org/guide/8_11/taking-solr-to-production.html
I have copy the configests from DSpace to /opt/solr/server/solr/configsets and I restart solr.
Unfortunately solr cores are not created.
Any help please

For everyone having the same porblem,

The solution was to move the configsets from /opt/solr/server/solr/configsets

that are suggested on the installation instructions.
to

/var/solr/data/configsets

configsets did not exists in /var/solr/data I had to created and set the right permissions.
