If an OSD is removed during the wrong conditions, it could lead to blocked IO or worst case data loss.
Check against global flags that limit the capabilities of Ceph to heal itself (norebalance, norecover, noout) and if there are degraded objects. Unfortunately, the 'safe-to-destroy' API endpoint will not help here as it only works as long as the OSD is still running. By the time the destroy button is enabled, the OSD needs to be stopped. Signed-off-by: Aaron Lauterer <a.laute...@proxmox.com> --- After the short discussion on the previous version [0] and the hints to ok-to-stop & safe-to-destroy I kept the original approach with the reason given in the commit message. But now the checks are run before opening the window and showing a loading screen.
