From ca499de1cbd43b8a1bcdcbf2d62d137a7557bbc6 Mon Sep 17 00:00:00 2001 From: Lisandro Pin Date: Thu, 21 Nov 2024 17:46:24 +0100 Subject: [PATCH] Improve EC shards rebalancing logic across racks (#6270) Improve EC shards rebalancing logic across racks. - Favor target shards with less preexisting shards, to ensure a fair distribution. - Randomize selection when multiple possible target shards are available. - Add logic to account for replication settings when selecting target shards (currently disabled). --- weed/shell/command_ec_common.go | 93 ++++++++++++----- weed/shell/command_ec_common_test.go | 84 ++++++++++++---- weed/shell/command_volume_list_test.go | 8 +- weed/shell/volume.ecshards.txt | 134 +++++++++++++++++++++++++ 4 files changed, 274 insertions(+), 45 deletions(-) create mode 100644 weed/shell/volume.ecshards.txt diff --git a/weed/shell/command_ec_common.go b/weed/shell/command_ec_common.go index 39c3f75c5..6e7ad7e43 100644 --- a/weed/shell/command_ec_common.go +++ b/weed/shell/command_ec_common.go @@ -3,6 +3,7 @@ package shell import ( "context" "fmt" + "math/rand" "github.com/seaweedfs/seaweedfs/weed/glog" "github.com/seaweedfs/seaweedfs/weed/operation" @@ -473,16 +474,19 @@ func balanceEcShardsAcrossRacks(commandEnv *CommandEnv, allEcNodes []*EcNode, ra return nil } -func doBalanceEcShardsAcrossRacks(commandEnv *CommandEnv, collection string, vid needle.VolumeId, locations []*EcNode, racks map[RackId]*EcRack, applyBalancing bool) error { +func countShardsByRack(vid needle.VolumeId, locations []*EcNode) map[string]int { + return groupByCount(locations, func(ecNode *EcNode) (id string, count int) { + shardBits := findEcVolumeShards(ecNode, vid) + return string(ecNode.rack), shardBits.ShardIdCount() + }) +} +func doBalanceEcShardsAcrossRacks(commandEnv *CommandEnv, collection string, vid needle.VolumeId, locations []*EcNode, racks map[RackId]*EcRack, applyBalancing bool) error { // calculate average number of shards an ec rack should have for one volume averageShardsPerEcRack := ceilDivide(erasure_coding.TotalShardsCount, len(racks)) // see the volume's shards are in how many racks, and how many in each rack -
