【标题描述】:

【测试类型：SQL功能】【测试版本：3.0.0】 gs_probackup恢复数据之后，gs_ctl build节点失败

【操作系统和硬件信息】(查询命令: cat /etc/system-release, uname -a):openEuler release 20.03 (LTS)

【测试环境】(单机/1主x备x级联备):1主1备

【被测功能】:行存表压缩

【测试类型】:功能测试

【数据库版本】(查询命令: gaussdb –V):gaussdb (openGauss 3.0.0 build 02c14696) compiled at 2022-04-01 18:12:19 commit 0 last mr

【预置条件】:数据库正常运行

使用sysbench导入随机数据；

1.修改sysbench表结构：CREATE TABLE sbtest%d(

id %s,

k INTEGER DEFAULT '0' NOT NULL,

c CHAR(120) DEFAULT '' NOT NULL,

pad CHAR(60) DEFAULT '' NOT NULL,

%s (id)

) with(compresstype=2）

2.使用sysbench导入数据；

【操作步骤】(请填写详细的操作步骤):

1. gs_probackup backup -B /home/omm/data_bak/ --instance=6001 -b full -h 127.0.0.1 -p 15400 -d test 备份数据

2. stop 集群

3. 删除主DN 目录下数据；

4. gs_probackup restore -B /home/omm/data_bak/ --instance=6001 恢复数据

5. gs_om -t start 启动集群失败；备机 wal

6. build 备机 /data/xydb/cluster/app/bin/gs_ctl build -D /data/xydb/cluster/dn_1 -M standby -b full -r 300

【预期输出】:成功拉起备机

【实际输出】:拉起失败

【原因分析】:

1. 这个问题的根因

2. 问题推断过程

3. 还有哪些原因可能造成类似现象

4. 该问题是否有临时规避措施

5. 问题解决方案

6. 预计修复问题时间
