主题: Re: [ceph-users] Full Ratio
Thank you!
Ceph version is 12.2
Also, can you let me know the format to set osd_backfill_full_ratio ?
Is it " ceph osd set -backfillfull-ratio .89 " ?

Hi,
if you are using an older Ceph version note that the mon_osd_near_full_ration and mon_osd_full_ration must be set in the config file on the MON hosts first and then the MONs restarted one after the other one.
If using a recent version there is a command ceph osd set-full-ratio and ceph osd set-nearfull-ratio
