在Centos7 greenplum 5.3版本上，我可以使用gpstart和createtb命令 但如果我使用如下，则会发生错误。
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
如果在其他数据库上运行相同的命令，它将挂起。 我将所有允许ip设置为＆＃34; trust＆＃34;
gpcheck -f hostfile_gpcheck -m mdw
有这样的错误，因为mount -a和mount -o remount命令不会挂载 并且与磁盘的当前参数不同
gpcheck:xxx:gpadmin-[ERROR]:-GPCHECK_ERROR host(xxx07.novalocal): XFS filesystem on device /dev/vda1 is missing the recommended mount option 'allocsize=16m'
gpcheck:xxx:gpadmin-[ERROR]:-GPCHECK_ERROR host(xxx07.novalocal): XFS filesystem on device /dev/vda1 is missing the recommended mount option 'nobarrier'
gpcheck:xxx:gpadmin-[ERROR]:-GPCHECK_ERROR host(xxx07.novalocal): XFS filesystem on device /dev/vda1 is missing the recommended mount option 'nodev'
gpcheck:xxx:gpadmin-[ERROR]:-GPCHECK_ERROR host(xxx07.novalocal): XFS filesystem on device /dev/vdb has 8 XFS mount options and 6 are expected
gpcheck:xxx:gpadmin-[ERROR]:-GPCHECK_ERROR host(xxx07.novalocal): XFS filesystem on device /dev/vdb is missing the recommended mount option 'allocsize=16m'
运行以下命令后，将使用empty和subnet2创建subnet1.out 没有创建。
gpcheckperf -f hostfile_gpchecknet_ic1 -r N -d /tmp > subnet1.out
gpcheckperf -f hostfile_gpchecknet_ic2 -r N -d /tmp > subnet2.out
以下命令可以成功运行
gpcheckperf -f hostfile_gpcheckperf -r ds -D \
-d /data/primary -d /data/primary \
-d /data/mirror -d /data/mirror
以下命令失败
gpadmin@xxxx ~]$ gpconfig -s max_connections

我认为错误与以下问题相同，尽管有不同的错误消息。 greenplum hang forever when doing any search or insert actions with psql and centos7
