Gerrit .pack size abnormal

[姜磊]

There has a git repository space issue on our gerrit system, and its size is abnormal.

We used git clone checkout to find out the size is only 550M, but its space size on the gerrit server has exceeded 30G and is still growing.

After checking, I found that there is a large number of pack directories on the server side, whether this is due to the user using the online editing feature.
Can these.pack files be cleaned, and do they cause any exceptions?

The version of gerrit we are currently using is 3.6.1

Do run git gc or repack on a regular basis (daily, hourly)?

Hi Sven

    Thanks for your support.

     No, we didn't run git gc or repack on a regular basis, but we use a script to back up all the repositories on this gerrit server every day.

     We have nearly 3,000 repositories on this gerrit server, but only this git repository has this problem, and only this git repository will be online editing by users, they will edit and update comments on the webpage.  Thanks

It is highly recommended that you run some sort of gc/repack job regularly. This increases performance and decreases disk-usage.
You can read more here:
https://gerrit-documentation.storage.googleapis.com/Documentation/3.6.1/repository-maintenance.html

As the user that runs gerrit you can issue a repack manually in this project and check the results.
 trouble-git$ git repack -A -d -b

 trouble-git$ git pack-refs --all

Or just:
  trouble-git$ git gc
