Hi, while trying to upgrade a cluster from 12.2.8 to 12.2.10 i'm experience issues with bluestore osds - so i canceled the upgrade and all bluestore osds are stopped now. After starting a bluestore osd i'm seeing a lot of slow requests caused by very high read rates. Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await r_await w_await svctm %util sda 45,00 187,00 767,00 39,00 482040,00 8660,00 1217,62 58,16 74,60 73,85 89,23 1,24 100,00 it reads permanently with 500MB/s from the disk and can't service client requests. Overall client read rate is at 10.9MiB/s rd I can't reproduce this with 12.2.8. Is this a known bug / regression?
