Hi, Which Solr version ?
Restart which node ? Solr ? ZK ? Only one node ? Collections are missing in Solr console (lost in Zookeeper) but cores are still present ? Why put Zk data and datalog in a "temp" directory (dataDir=/applis/24374-iplsp-00/IPLS/apache-zookeeper-3.5.5-bin/temp) ? This directory is never purged ? Why launch Solr with ZKHOST and other settings in the command line instead of in solr.in.sh ? There is a similar discussion thread these days "All cores gone along with all solr configuration upon reboot".
