How can I increase or decrease the number of osd backfilling instantly
Hi All, I'd like to speed up or slow down osd recovery in ceph v18.2.1. According to the page ( https://www.suse.com/ko-kr/support/kb/doc/?id=000019693 ), I understand that osd_max_backfills, osd_recovery_max_active have to be increased or decreased. but It seems not to impact the number of osd backfilling instantly. so I tried to restart all of the osds even though I didn't need to restart osds. I wonder how long it takes to show that the number of backfilling is increased or decreased If the osds is not restarted. and Is there a way to increase or decrease the number of backfilling instantly after the configuration is changed.
Hello Jaemin, it's mclock now. Read this: https://docs.ceph.com/en/reef/rados/configuration/mclock-config-ref/ and apply that: https://docs.ceph.com/en/reef/rados/configuration/mclock-config-ref/#steps-t... Best, Malte On 28.06.24 08:54, Jaemin Joo wrote:
