Viachaslau Kabak commented on SOLR-11660:
-----------------------------------------
Hi,
sure
1. Backup collection
(http://serverName:SOLR_PORT/solr/admin/collections?action=BACKUP&name=CollectionName&collection=pCollectionName&location=tmpSolrDir)
2. Restore collection (even on another solr Cloud):
2a.
http://serverName:SOLR_PORT/solr/admin/collections?action=DELETE&name=pCollectionName
2b.
http://serverName:SOLR_PORT/solr/admin/collections?action=RESTORE&name=CollectionName&collection=CollectionName&location=tmpSolrDir
3. Try to update index from hybris application
Expected steps: index is updated for leader and for followers
Current results: index is updated only on followers, on the leader there is an
old index, there are warnings in logs:
{noformat}
o.a.s.u.p.DistributedUpdateProcessor Ignoring commit while not ACTIVE - state:
BUFFERING replay: false
{noformat}
Collection reload helps.
Note: if to restart solr on all instances before to update index from hybris
application - new index will be available on all instances and no warnings are
in the log

> application - we have new index on follower and old index on leader.
> The Reload on collection helps to make index up-to-date on leader.
