Issue "divide by zero" on Prometheus 1.x during migration to Prometheus 2.x after file system full

[craph]

Hello,

I post this issue because I have a major issue with Prometheus 1.x after a file system full.

I am using GitLab-ce docker image in production and on monday morning we had a file system full and the GitLab instance including Prometheus inside break down.

After adding some space I tried to do the migration to Prometheus 2.x.

I have open an issue here : https://gitlab.com/gitlab-org/gitlab-ce/issues/54470

But may be the tsdb is corrupted.

So my question is :
Is it possible to repair the Prometheus data ?

Thank you very much for your help.

Best regards
