Hi, I’ve just upgrade my cluster from Jewel to Nautilus (still running filestore). Since I'v stopped deepscrub for several days for this upgrade, now I got warning of "3 pgs not deep-scrubbed in time”. I tried to increase osd_max_scrubs to 3, osd_scrub_load_threshold to 5.0 and osd_deep_scrub_stride to 1048576 in order to accelerate the deepscrub processes. But deep scrubs seem still very slow. Is there any other way to improve the deep scrub performance? The cluster has 8 nodes, 52 HDD OSDs, 168 TiB / 313 TiB avail data, cluster traffic is low at present. BR, Xu Yun
