Centos7 greenplum 5.3バージョンでは、gpstartコマンドとcreatetbコマンドを使用できます。 ただし、以下のように使用するとエラーが発生します。Greenplum ERROR：1つ以上のセグメントでリソースを取得できませんでした
testdb=# select * FROM test_vb;
ERROR: failed to acquire resources on one or more segments
DETAIL: FATAL: database "testdb" does not exist
(seg3 xxx.xxx.xxx:xxx:40003)
testdb=# failed to acquire resources on one or more segments
testdb-# ERROR: failed to acquire resources on one or more segments
他のデータベースで同じコマンドを実行すると、ハングします。 は、私はすべてがマウント-aとマウント-o再マウントコマンドが をマウントしたディスク

の現在のパラメータと異ならないので、
gpcheck -f hostfile_gpcheck -m mdw
はこのようなエラーが発生しました「信頼」でIPを許可する設定しました次のコマンドを実行すると、空とサブネット2でsubnet1.outが作成されます が作成されません。
gpcheckperf -f hostfile_gpchecknet_ic1 -r N -d /tmp > subnet1.out
gpcheckperf -f hostfile_gpchecknet_ic2 -r N -d /tmp > subnet2.out
次のコマンドが成功し、次のコマンドはpsxxx.xxx.xxx.52がローカルアドレスである（以下のようにgplogfilterのログ・ファイル
