Shell script to stop and start the services of gerrit

[kamal gumparthi]

Hi,

Could you please provide the shell script which need to call ./gerrit.sh stop and ./gerrit.start  gerrit services. We dont want ./gerrit.sh restart since it is causing problem now a days.

Requirements:

1.First it should stop the services.

2.Check if the services stopped or not

3.If stopped then do start  after 5 minutes else do first point again else quit.

4.If start is working then check the status of the process.

[Dave Borowitz]

The script you want is gerrit.sh. Can you clarify, what kind of problems is it causing you? If there is a bug in it, it would be better to fix it for everybody than to write a new script.

Hi Dave,

Thanks for the reply.

We have an issue at the time of gerrit restart in crontab.This was working since many days but recent days it is not working. So decided to create one script to call ./gerritsh stop and start instead of ./gerrit.sh restart.

Posted this issue earlier. Please see the below link.

Also one more thing today we have got other error while crotnab schedule ran. Manual stop and start is working fine.

Manual Stop and start is also not working from today onwards. Same error showing in the error_log file.

Currently we are not able to restart/stop/start the gerrit services.

[Björn Pedersen]

Hi,

possible reasons:
 unclean shutdown (due to powerloss etc.. ) - > remove the lock file manually
 another gerrit process still running and  pid-file lost/wrong ( check with ps...)



A of course mentioning  the gerrit version would help.
Is there any error logged in logs/error_log?

Björn

Hi Pederson,

Please find the attached document.

I have explained the issue with screenshots and included error_log as well.

Please let me know which lock file do you want me to remove? changes_0014/open/write.lock file?

Can you run a git gc and gerrit gc to see if there are some corrupted objects found. If something found the gc log please rectify the issues and run the steps manually. We do have some script to start gerrit service and stop it. Never face any issues with that.
