This is a bit too low, e.g. we've seen RabbitMQ network -splits in production. - -This 12.9s amount is equal as 0.2*(2^1+2^2+..2^5), where 0.2 is a -retry timeout (RTO) that is calculated by kernel on a per-socket -basis. But in fast local networks it usually almost equal to minimum -values of 0.2s hardcoded in linux kernel (and BTW, RFC says that -minimum value should be 1s). - -On the other hand, comment in netconfig.pp says that our target -timeout is ~54 seconds. And changing tcp_retries2 to 7 is consistent -with that comment - tests an live env show that resulting timeout is -~52.2s - -Change-Id: Ib52f40ef1017a9da5a29cd62fb744a4597860763 ---- - deployment/puppet/osnailyfacter/manifests/netconfig/netconfig.pp | 2 +- - tests/noop/spec/hosts/netconfig/netconfig_spec.rb | 2 +- - 2 files changed, 2 insertions(+), 2 deletions(-) - -diff --git a/deployment/puppet/osnailyfacter/manifests/netconfig/netconfig.pp b/deployment/puppet/osnailyfacter/manifests/netconfig/netconfig.pp -index 78d5975..42579ac 100644 ---- a/deployment/puppet/osnailyfacter/manifests/netconfig/netconfig.pp -+++ b/deployment/puppet/osnailyfacter/manifests/netconfig/netconfig.pp -@@ -42,7 +42,7 @@ class osnailyfacter::netconfig::netconfig { - tcpka_time => '30', - tcpka_probes => '8', - tcpka_intvl => '3', -- tcp_retries2 => '5', -+ tcp_retries2 => '7', - } - - # increase network backlog for performance on fast networks -diff --git a/tests/noop/spec/hosts/netconfig/netconfig_spec.rb b/tests/noop/spec/hosts/netconfig/netconfig_spec.rb -index c175aed..80ea0f2 100644 ---- a/tests/noop/spec/hosts/netconfig/netconfig_spec.rb -+++ b/tests/noop/spec/hosts/netconfig/netconfig_spec.rb -@@ -27,7 +27,7 @@ describe manifest do - 'tcpka_time' => '30', - 'tcpka_probes' => '8', - 'tcpka_intvl' => '3', -- 'tcp_retries2' => '5', -+ 'tcp_retries2' => '7', - ) } - it { should contain_sysctl__value('net.core.netdev_max_backlog').with('value' => '261144') } - it { should contain_class('sysfs') } |
