hello

When the given index is being reindexed it is closed hence not available for the users.  
What is the proper way to do reindex on the production system where the index should be highly available?

Regards  
Jacek

Hey,

can you explain, what exactly you are doing? A reindex operation does not close the index, so if that happens, another component/script has done this.

Or are you talking about snapshot/restore instead of reindex here (which also does not require a closed index, but the restore operation requires the index not to exist).

A bit more about your setup would be super useful here.

hello,

Yes, that was another component that was closing the index not the ES.  
Thank You.
