how to patch

Please help to patch Storage-17443 for Ginger

Patch branch is bugfix-release-ecs-3.1-Ginger-7468cdof

git checkout Destination branch: bugfix-release-ecs-3.1-Ginger-7468cdof

git pull origin bugfix-release-ecs-3.1-Ginger-7468cdof

enter JIRA  found commit :17443

git cherry-pick commit_number

enter container:  tools/webstorage/enter.sh .

start build(about 15mins) :  ./gradew clean all

scp  build/lib/Storageos-blobsvc.jar  admin@10.247.198.60:/home/admin

ls

md5sum Storageos-blobsvc.jar

cat  MACHINES

viprapplypatch MACHINES Storageos-blobsvc.jar

restart svc  :    viprexec -c  kill `pidof blobsvc`

涉及到权限在命令前加sudo

停止 viprexec -c ` md5sum  /opt/Storageos/lib/Storageos-blob.jar`

针对JIRA STORAGE-10000创建一个分支，gitcheckout -b bugfix-STORAGE-10000-branch-name

两种修改同步devkit和windows的方法

1. 在windows， git commit -a -m "some comment"

    再git push origin bugfix-STORAGE-10000-branch-name

2. 在devkit上，git pull origin bugfix-STORAGE-10000-branch-name

方法二：

1. 在windows，git diff > temp.diff

2. 在windows，scp temo.diff到devkit

3. 在devkit上 git apply xxx.diff

 

Devkit

./gradlew :client:jar (编译client模块)

 

make clean clobber rpm&& tools/webstorage/deployment.sh SetupViprNodes（Setup ECS Datanodes）

 

登录container：        nsenter -i -m -p -u -t `pidof cm`

   查看storageserver进程   ps -ef| grep storageserver

   kill进程：              kill pidnum 或者  kill `pidof storageserver`

   查看进程是否被kill：  ps -ef | grepstorageserver

   重新启动storageserver进程： /opt/storageos/bin/monitor -u 444 -g 444 -c / -l/opt/storageos/logs/storageserver.out -p /var/run/storageserver.pid -i 40 -I 40/opt/storageos/bin/storageserver \"--config\" /opt/storageos/conf/storageserver.conf\"--partitionconfig\" /data/partitions.json

   查看进程是否重新启动： ps -ef | grep storageserver

    查看log信息： cd /var/log

               vim dataheadsvc.log 或者 tail -F dataheadsvc.log

 

 

Apply patch：

1.修改了代码以后

./gradlew clean all

2.替换jar包

在container中的/opt/storageos/lib/目录下（以client为例）

mv storageos-client.jarstorageos-client.jar.old && scproot@10.247.97.202:/opt/MyWorkSpace/EMC/Storage/Quasar/Std/storage/datasvc/libs/client/build/libs/storageos-client.jar .

3.重启service，有两种方法重启进程

方法一： ()

    1. servicestorageos_dataservice 速度比较慢

    2.用curlhttp://localhost:9101/stats/dt/DTInitStatDT是否恢复成功

 

方法二：

    1.kill `pidof***`

    kill`pidof  dataheadsvc`

 

UT Test

以Client的BufferedFileWriter UT为例

 

在log4j2.xml  中下面这条语句的意思就是改log level为DEBUG

<Loggername="com.emc.storageos.data.object" level="DEBUG" />

 

将改好log4j2.xml放在这里：datasvc/libs/client/src/main/test

 

运行UT： ./gradlew:client:test  -Dtest.single=BufferedFileWriterTest  -Plog4jConf=datasvc/libs/client/src/main/test/log4j2.xml

 

查看log ：vi datasvc/libs/client/build/test.log
