gitlab-ce 12.X : how do I find the hashed storage path of a repository on the server?

Question

With gitlab-ce-12.x, Geo requires the storage path to be hashed (https://docs.gitlab.com/ee/administration/repository_storage_types.html)

For a given repository, the data will therefore be stored in : "@hashed/#{hash[0..1]}/#{hash[2..3]}/#{hash}.git"

From a practical point of view, say I have a repository whose URL is

https://my-gitlab-server/Group1/project1.git

How do I work out the path to the storage on the server ? i.e. how do i find the value of

#{hash[0..1]}/#{hash[2..3]}/#{hash}

Thanks

I found the answer to my question.

In order to get the hashed storage location of a project, you first need to get the project id of the project repository.

Once you get that project id, say your project id is 1, you get the hash this way :

Say project.id is 1

echo -n 1 | sha256sum

=> You get the HASH 6b86b273ff34fce19d6b804eff5a3f5747ada4eaa22f1d49c01e52ddb7875b4b

The hashed storage location of your repository on the server will therefore be :

server/@hashed/6b/86/6b86b273ff34fce19d6b804eff5a3f5747ada4eaa22f1d49c01e52ddb7875b4b.git
