I just yesterday updated by Ceph cluster from Quincy (17.2.7) to Reef (18.2.4, purely by accident; I didn't realize I was getting it THE EXACT SECOND it was pushed out). The upgrade resolved an issue I was having with HTTP 500 errors on the RGW UI, but seems to have created an issue in the dashboard with the Block / Images screen. I see errors that come up as alerts: 0 - Unknown Error * Http failure response for api/prometheus: 0 Unknown Error * Http failure reponse for api/prometheus/rules: 0 Unknown Error * Http failure response for api/summary: 0 Unknown Error All the other menu options on the dashboard are working. I thought it was a UI issue, but having read the notes on 18.2.4, I wonder if I've hit a bug, or if there's something wonky with the RBD images in some of our pools. We're using Ceph mostly for OpenStack. The syslog on the mgr server shows an error and traceback, when I try to use the Block / Images menu link. Notably I see Jul 25 09:13:15 ceph00.cecnet.gmu.edu ceph-mgr[2293091]: librbd::DiffIterate: fast diff enabled just before the crash, and there's mention of this function in the release notes. I'm going to try and use the rbd command and query some of the pools and images to see if I can narrow down specifically what's going on. If anyone's got some suggestions, I'd love to hear them. I can drop additional information from the logs if needed. I don't THINK there were errors prior to the upgrade, but I can't say for sure since I've been working in other parts of the Ceph UI.
