greenplum是2(master)+7(segment)的集群规模

系统刚准备上线，是用来做统计数据库的，正在帮忙一个hadoop集群核对其数据的准确性，在这个greenplum库中入了清单数据

后检查分析是部分建表语句存在问题，没有指定字段做分布键，也没有指定其是随机分布，导致默认为第一个字段做为分布键导致数据倾斜。

发现数据库非常慢，几乎是不可用，检查greenplum的状态情况

1、检查greenplum数据库的状态

2、检查数据库服务器的情况

3、数据库上删除清单表

用psql连接数据库，执行drop table 表名，执行后，等待大半天也没反应，使用gpssh -f检查服务器的io使用情况，segment服务器的IO没有读写操作，证明数据库已经没办法分发命令下去。

Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util sdb 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 sda 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 sr0 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00

4、分别登陆sdw2和sdw6

#cd /data/primary/gpseg4/gp_log

#ls -ltrh

目录下有gpdb-日期.csv文件，直接执行

#rm -rf *.csv

每个gpseg下的gp_log都执行同样的删除操作，执行完后，空间释放得非常少。

5、停数据库

执行gpstop

报：-gpstop failed(Reason=‘FATAL: the database system is shutting down‘) exiting ...

gpstop停不下来。

6、检查进程

gpssh -h sdw1 -h sdw2 -h sdw3 -h sdw4 -h sdw5 -h sdw6 -h sdw7 -h mdw -h smdw "ps -ef |grep postgres"

数据库segment上进程没有停。下面是一台segment上的进程：

7、在master上执行

#gpstop -af

报：-gpstop failed(Reason=‘FATAL: the database system is shutting down‘) exiting ...

同样停不了库

[email protected]:~> gpstop -M fast 20150227:18:42:01:021768 gpstop:mdw:gpadmin-[INFO]:-Starting gpstop with args: -M fast 20150227:18:42:01:021768 gpstop:mdw:gpadmin-[INFO]:-Gathering information and validating the environment... 20150227:18:42:01:021768 gpstop:mdw:gpadmin-[INFO]:-Obtaining Greenplum Master catalog information 20150227:18:42:01:021768 gpstop:mdw:gpadmin-[INFO]:-Obtaining Segment details from master... 20150227:18:42:01:021768 gpstop:mdw:gpadmin-[CRITICAL]:-gpstop failed. (Reason=‘FATAL: the database system is shutting down ‘) exiting...

同样不行。

8、直接kill

gpssh -h sdw1 -h sdw2 -h sdw3 -h sdw4 -h sdw5 -h sdw6 -h sdw7 -h mdw -h smdw "for i in `ps -ef |grep postgres |awk {‘print $2‘}`;do kill $i; done"

使用上面的检查，segment上的进程都已停止，但是master上的部分进程没有停。

9、停止master进程

mdw -h smdw ps -ef |grep postgres [ mdw] gpadmin 15765 15724 0 17:52 pts/11 00:00:00 grep postgres [ mdw] gpadmin 38876 41830 0 Feb26 ? 00:05:11 postgres: port 5432, cems cems 198.168.11.12(51943) con6959 198.168.11.12(51943) cmd24705 BIND [ mdw] gpadmin 41830 1 0 Feb04 ? 00:00:07 /usr/local/greenplum-db-4.3.3.1/bin/postgres -D /data/master/gpseg-1 -p 5432 -b 1 -z 28 --silent-mode=true -i -M master -C -1 -x 58 -E [ mdw] gpadmin 41838 41830 0 Feb04 ? 00:10:18 postgres: port 5432, master logger process [ mdw] gpadmin 41844 41830 0 Feb04 ? 00:00:18 postgres: port 5432, stats collector process [ mdw] gpadmin 41845 41830 0 Feb04 ? 00:05:02 postgres: port 5432, writer process [ mdw] gpadmin 41846 41830 0 Feb04 ? 00:00:55 postgres: port 5432, checkpoint process [ mdw] gpadmin 41847 41830 0 Feb04 ? 00:00:13 postgres: port 5432, seqserver process [ mdw] gpadmin 41848 41830 0 Feb04 ? 00:04:33 postgres: port 5432, ftsprobe process [ mdw] gpadmin 41851 41830 0 Feb04 ? 00:00:49 postgres: port 5432, sweeper process

执行gkill postgres，没反应。

直接使用kill 41830，没反应，不行。

执行pg_ctl stop -D /data/master/gpseg-1

>pg_ctl stop -D /data/master/gpseg-1

waiting for server to shut down .........................................failed

pg_ctl:server does not shut down

应是新版本中对于进程做了保护，不能直接kill了。

9、使用pg_ctl停库

[email protected]:~> pg_ctl --help pg_ctl is a utility to start, stop, restart, reload configuration files, report the status of a PostgreSQL server, or signal a PostgreSQL process.

Usage: pg_ctl start [-w] [-t SECS] [-D DATADIR] [-s] [-l FILENAME] [-o "OPTIONS"] pg_ctl stop [-W] [-t SECS] [-D DATADIR] [-s] [-m SHUTDOWN-MODE] pg_ctl restart [-w] [-t SECS] [-D DATADIR] [-s] [-m SHUTDOWN-MODE] [-o "OPTIONS"] pg_ctl reload [-D DATADIR] [-s] pg_ctl status [-D DATADIR] pg_ctl kill SIGNALNAME PID

Common options: -D, --pgdata DATADIR location of the database storage area -s, --silent only print errors, no informational messages -t SECS seconds to wait when using -w option -w wait until operation completes -W do not wait until operation completes --help show this help, then exit --version output version information, then exit --gp-version output Greenplum version information, then exit (The default is to wait for shutdown, but not for start or restart.)

If the -D option is omitted, the environment variable PGDATA is used.

Options for start or restart: -l, --log FILENAME write (or append) server log to FILENAME -o OPTIONS command line options to pass to postgres (PostgreSQL server executable) -p PATH-TO-POSTGRES normally not necessary -c, --core-files allow postgres to produce core files

Options for stop or restart: -m SHUTDOWN-MODE can be "smart", "fast", or "immediate"

Shutdown modes are: smart quit after all clients have disconnected fast quit directly, with proper shutdown immediate quit without complete shutdown; will lead to recovery on restart

Allowed signal names for kill: HUP INT QUIT ABRT TERM USR1 USR2

经分析，应是hosts有问题了，直接ssh hosts的域名不行，直接ssh ip地址没有问题。

经检查，segment上的hosts有问题，和hadoop集群的hosts一样了。应该hadoop集群是后安装的，当时我要同事帮忙scp修改的hosts，估计把gp的集群也覆盖了。

修改hosts完后，

再执行gprecoverseg命令
