Hello I was testing some backup/restore scenarios.
1 of them is Solr7.6 in a docker container(7.6.0-slim), set up as SolrCloud, with zookeeper. The steps are as follows: 1. Manually delete the data folder. 2. Restart the container. The process is now in error mode, complaining that it cannot find the cores. 3. Fix the install, meaning create new data folders, which are empty at this point. 4. Restart the container again, to pick up the empty folders and not be in error anymore. 5. Perform the restore 6. Check if everything is available again The problem is between step 4 and 5. After step 4, it takes several minutes before solr actually responds to curl commands. Once responsive, the restore happened just fine. But it's very stressful in a situation where you have to restore a production environment and the process just doesn't respond for 5-10 minutes. We're talking about 20GB of data here, so not very much, but not little either. Is it normal that it takes so long before solr responds? If not, what should I look at in order to find the cause? I have asked this before recently, though the wording was confusing. This should be clearer. Kind regards, Koen De Groote
