Package: prometheus Version: 1.5.2+ds-2+b3 Severity: important Dear Maintainer,
I've blindly upgraded prometheus 1.5.2+ds-2+b3 to 2.7.1+ds-3+b11 and this automatically removed all my historical data from /var/lib/prometheus/metrics/. I had to rollback because new version requires new configuration and finding solution on keeping historical data. As developers provided no way to convert to new format most probable solution will be to stuck on pre 2.0 version. Dramatic changes like that are dangerous and should not happen so easy. -- System Information: Debian Release: 10.1 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable'), (500, 'oldstable'), (81, 'testing'), (80, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-5-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) Versions of packages prometheus depends on: ii daemon 0.6.4-1+b2 ii libc6 2.28-10 ii libjs-bootstrap 3.4.1+dfsg-1 ii libjs-eonasdan-bootstrap-datetimepicker 4.17.47-3 ii libjs-jquery 3.3.1~dfsg-3 ii libjs-jquery-hotkeys 0~20130707+git2d51e3a9+dfsg-2 ii libjs-moment 2.24.0+ds-1 ii libjs-mustache 2.3.2-1 ii libjs-rickshaw 1.5.1.dfsg-2 Versions of packages prometheus recommends: ii prometheus-node-exporter 0.17.0+ds-3+b11 prometheus suggests no packages. -- Configuration Files: /etc/default/prometheus changed [not included] /etc/prometheus/prometheus.yml changed [not included] -- debconf information: prometheus/remove-version1-database: true
