find all repositories that failed: link in mail)

(OPTIONAL) Check /var/log/gitlab/gitlab-rails/repocheck.log for additional info,

open specific project Menu->Admin->Projects-><the failed project> and search for Gitaly relative path

something like this: @hashed/48/b3/48b361d46638bfa4eee090c158a750a69c7beec3a62e703e2801125551b1b157.git

ssh into gitlab vm and save the path into a variable for easiness of access:

export hashed_path="<paste_here_the_hashed_path>"

then check git cache

sudo -u git /opt/gitlab/embedded/bin/git -C "/var/opt/gitlab/git-data/repositories/${hashed_path}" fsck

and check if there are any errors like

error: Could not read 098b53ffbe581e25b…
failed to parse commit 098b53ffbe581e25b… from object database for commit-graph

now run garbage collector gc with

sudo -u git /opt/gitlab/embedded/bin/git -C "/var/opt/gitlab/git-data/repositories/${hashed_path}" gc

and check again repository with fsck

sudo -u git /opt/gitlab/embedded/bin/git -C "/var/opt/gitlab/git-data/repositories/${hashed_path}" fsck

and errors and fails should be cleared

run again Trigger repository check in check if repository check has passed successfully.

If it was successful then this repository shouldn’t be in repository list that have failed to pass the repository check:
