From d3b209c8e19edfdeb13035e1d8f4b4815cf77f08 Mon Sep 17 00:00:00 2001 From: Dmitrii Stepanov Date: Wed, 4 Sep 2024 09:30:56 +0300 Subject: [PATCH] [#1337] shard: Disable background rebuild Since `frostfs-cli control shards rebuild` command was added, there is no need for background rebuild now. For failover tests used used value 1 to rebuild only schema change.
