Gaussdb T分布式集群可通过gs_upgradectl对数据库进行离线版本升级，本文演示将数据库从GaussDB_100_1.0.0.B019 Release 0b7bb43升级至GaussDB_100_1.0.1.SPC2.B003 Release 3ae9d6c的整个过程。
1.gs_upgradectl命令帮助
[omm@gaussdb1 script]$ which gs_upgradectl /gaussdb/gaussTools/wisequery/script/gs_upgradectl [omm@gaussdb1 script]$ gs_upgradectl --help gs_upgradectl is a utility to upgrade a cluster. Usage: gs_upgradectl -? | --help gs_upgradectl -V | --version gs_upgradectl -t upgrade-type -X XMLFILE [-l LOGFILE] gs_upgradectl -t offline-upgrade -X XMLFILE [-l LOGFILE] gs_upgradectl -t offline-rollback -X XMLFILE [-l LOGFILE] General options: -?, --help Show help information for this utility, and exit the command line mode. -V, --version Show version information. -t Subcommand for upgrade. It can be upgrade-type, offline-upgrade, offline-rollback. -X Path of the XML configuration file of the later version cluster. -l Path of log file. [omm@gaussdb1 script]$
参数解释：
-X 集群配置文件 -l 日志文件 -t 升级类型，其中upgrade-type为判断本次升级类型，systable-upgrade为离线小版本升级,binary-upgrade为离线二进制升级。
2.升级前信息收集
a).集群状态
[omm@gaussdb1 script]$ gs_om -t status Set output to terminal. --------------------------------------------------------------------Cluster Status-------------------------------------------------------------------- az_state : single_az cluster_state : Normal balanced : true ----------------------------------------------------------------------AZ Status----------------------------------------------------------------------- AZ:AZ1 ROLE:primary STATUS:ONLINE ---------------------------------------------------------------------Host Status---------------------------------------------------------------------- HOST:gaussdb1 AZ:AZ1 STATUS:ONLINE IP:10.111.76.22 HOST:gaussdb2 AZ:AZ1 STATUS:ONLINE IP:10.111.76.23 HOST:gaussdb3 AZ:AZ1 STATUS:ONLINE IP:10.111.76.24 HOST:gaussdb4 AZ:AZ1 STATUS:ONLINE IP:10.111.76.25 ----------------------------------------------------------------Cluster Manager Status---------------------------------------------------------------- INSTANCE:CM1 ROLE:primary STATUS:ONLINE HOST:gaussdb1 ID:601 INSTANCE:CM2 ROLE:slave STATUS:ONLINE HOST:gaussdb2 ID:602 ---------------------------------------------------------------------ETCD Status---------------------------------------------------------------------- INSTANCE:ETCD1 ROLE:follower STATUS:ONLINE HOST:gaussdb1 ID:701 PORT:2379 DataDir:/gaussdb/data/etcd/data_etcd1 INSTANCE:ETCD2 ROLE:leader STATUS:ONLINE HOST:gaussdb2 ID:702 PORT:2379 DataDir:/gaussdb/data/etcd/data_etcd1 INSTANCE:ETCD3 ROLE:follower STATUS:ONLINE HOST:gaussdb3 ID:703 PORT:2379 DataDir:/gaussdb/data/etcd/data_etcd1 ----------------------------------------------------------------------CN Status----------------------------------------------------------------------- INSTANCE:cn_401 ROLE:no role STATUS:ONLINE HOST:gaussdb1 ID:401 PORT:8000 DataDir:/gaussdb/data/cn INSTANCE:cn_402 ROLE:no role STATUS:ONLINE HOST:gaussdb2 ID:402 PORT:8000 DataDir:/gaussdb/data/cn INSTANCE:cn_403 ROLE:no role STATUS:ONLINE HOST:gaussdb3 ID:403 PORT:8000 DataDir:/gaussdb/data/cn INSTANCE:cn_404 ROLE:no role STATUS:ONLINE HOST:gaussdb4 ID:404 PORT:8000 DataDir:/gaussdb/data/cn ---------------------------------------------------------Instances Status in Group (group_1)---------------------------------------------------------- INSTANCE:DB1_1 ROLE:primary STATUS:ONLINE HOST:gaussdb1 ID:1 PORT:4000 DataDir:/gaussdb/data/dn1 INSTANCE:DB1_2 ROLE:standby STATUS:ONLINE HOST:gaussdb2 ID:2 PORT:4000 DataDir:/gaussdb/data/dn1 ---------------------------------------------------------Instances Status in Group (group_2)---------------------------------------------------------- INSTANCE:DB2_3 ROLE:primary STATUS:ONLINE HOST:gaussdb3 ID:3 PORT:4000 DataDir:/gaussdb/data/dn3 INSTANCE:DB2_4 ROLE:standby STATUS:ONLINE HOST:gaussdb4 ID:4 PORT:4000 DataDir:/gaussdb/data/dn3 --------------------------------------------------Manage IP-------------------------------------------------- HOST:gaussdb1 IP:10.111.76.22 HOST:gaussdb2 IP:10.111.76.23 HOST:gaussdb3 IP:10.111.76.24 HOST:gaussdb4 IP:10.111.76.25 [omm@gaussdb1 script]$
b).版本信息
SQL> select * from v$version; VERSION ---------------------------------------------------------------- GaussDB_100_1.0.0.B019 Release 0b7bb43 ZENGINE 0b7bb43 3 rows fetched.
c).数据同步情况
[omm@gaussdb1 script]$ zsql / as sysdba 10.111.76.22:4000 -D /gaussdb/data/dn1 Warning: SSL connection to server without CA certificate is insecure. Continue anyway? (y/n):y connected. SQL> SELECT LOCAL_LFN, PEER_LFN FROM DV_HA_SYNC_INFO; LOCAL_LFN PEER_LFN -------------------- -------------------- 1646 1646 1 rows fetched. SQL> [omm@gaussdb3 ~]$ zsql / as sysdba 10.111.76.24:4000 -D /gaussdb/data/dn3 -q connected. SQL> SELECT LOCAL_LFN, PEER_LFN FROM DV_HA_SYNC_INFO; LOCAL_LFN PEER_LFN -------------------- -------------------- 1631 1631 1 rows fetched. SQL>
3.新版本介质准备
[root@gaussdb1 script]# mkdir -p /opt/software/upgrade [root@gaussdb1 upgrade]# tar -zxvf ../1.0.1/GaussDB_100_1.0.1-CLUSTER-REDHAT7.5-64bit.tar.gz [root@gaussdb1 upgrade]# ls -lrt total 54476 drwx------ 6 omm dbgrp 4096 Dec 14 11:40 script drwx------ 7 omm dbgrp 196 Dec 14 11:40 lib -rwx------ 1 omm dbgrp 8038086 Dec 14 11:43 GaussDB_100_1.0.1-DATABASE-REDHAT-64bit.tar.gz -rwx------ 1 omm dbgrp 128240 Dec 14 11:46 GaussDB_100_1.0.1-ROACH-REDHAT-64bit.tar.gz -rwx------ 1 omm dbgrp 47604191 Dec 14 11:46 GaussDB_100_1.0.1-CM-REDHAT-64bit.tar.gz drwx------ 5 omm dbgrp 49 Dec 14 11:46 shardingscript [root@gaussdb1 script]# cp /opt/soft/GaussDB_100-Upgrade-WhiteList.txt /gaussdb/gaussTools/wisequery [root@gaussdb1 script]#
4.升级前检查磁盘空间
Gaussdb T升级前会对数据库进行备份，请确保空闲空间足够。
[omm@gaussdb1 script]$ df -lh /gaussdb Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_data-lv_data 150G 42G 109G 28% /gaussdb [omm@gaussdb1 script]$ [omm@gaussdb2 ~]$ df -lh /gaussdb Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_data-lv_data 150G 42G 109G 28% /gaussdb [omm@gaussdb2 ~]$ [omm@gaussdb3 ~]$ df -lh /gaussdb Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_data-lv_data 150G 42G 109G 28% /gaussdb [omm@gaussdb3 ~]$ [omm@gaussdb4 ~]$ df -lh /gaussdb/ Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_data-lv_data 150G 42G 109G 28% /gaussdb [omm@gaussdb4 ~]$
5.升级前置检查
cd /opt/software/upgrade/script ./gs_preinstall -U omm -G dbgrp -X /opt/clusterconfig.xml --alarm-type=1 --operation=upgrade
检查日志
[root@gaussdb1 script]# ./gs_preinstall -U omm -G dbgrp -X /opt/clusterconfig.xml --alarm-type=1 --operation=upgrade Parsing the configuration file. Successfully parsed the configuration file.

6.检查升级类型
systable-upgrade为离线小版本升级,binary-upgrade为离线二进制升级。本次升级为离线小版本升级。
[omm@gaussdb1 script]$ gs_upgradectl -t upgrade-type -X /opt/clusterconfig.xml Checking upgrade type. Successfully checked upgrade type. Upgrade type: systable-upgrade. [omm@gaussdb1 script]$
