I have a PG that hasn't been scrubbed in over a month and not deep-scrubbed in over two months. I tried forcing with `ceph pg (deep-)scrub` but with no success. Looking at the logs of that PG's primary OSD it looks like every once in a while it attempts (and apparently fails) to scrub that PG, along with two others, over and over. For example: 2023-07-19T16:26:07.082 ... 24.3ea scrub starts 2023-07-19T16:26:10.284 ... 27.aae scrub starts 2023-07-19T16:26:11.169 ... 24.aa scrub starts 2023-07-19T16:26:12.153 ... 24.3ea scrub starts 2023-07-19T16:26:13.346 ... 27.aae scrub starts 2023-07-19T16:26:16.239 ... 24.aa scrub starts ... Lines like that are repeated throughout the log file. Has anyone seen something similar? How can I debug this? I am running 17.2.5 Vlad
