Hi, After a disk failure, the number of PGs not deep scrubbed started to increase (Ceph Quincy). Here is an example PG: https://gist.githubusercontent.com/Badb0yBadb0y/afe9b26fbae72c79c9430585bf4e5f23/raw/7e794b7d6245cc13276afec20fd8b5a5a7fbd082/PG%2520Query Normally, when this happens, I observe some stuck operations and increased latency on certain OSDs (restarting the affected OSD usually resolves the issue, and the not deep-scrubbed PGs get scrubbed within a day). However, this time I don’t see any obvious problems. Could you please help review the attached not deep-scrubbed PG and let me know if you notice anything unusual? For context, the disk was re-added yesterday and rebalance is still in progress, but the not deep-scrubbed alerts started appearing before the disk was added back. Thank you.
