Ceph

Hi all,

I’m trying to limit an ongoing backfill, but it seems osd max backfills is somehow set to 1000 and I can’t get it lower:

[root@ceph301 ~]# ceph config show osd.20 osd_max_backfills
1000
[root@ceph301 ~]# ceph config rm osd.20 osd_max_backfills
[root@ceph301 ~]# ceph config show osd.20 osd_max_backfills
1000
[root@ceph301 ~]# ceph config set osd.20 osd_max_backfills 1
[root@ceph301 ~]# ceph config show osd.20 osd_max_backfills
1000
[root@ceph301 ~]# ceph config rm osd.20 osd_max_backfills
[root@ceph301 ~]# ceph config set osd osd_max_backfills 1
[root@ceph301 ~]# ceph config show osd.20 osd_max_backfills
1000

Also with injecting:
ceph tell osd.20 injectargs '--osd_max_backfills 1' {}
osd_max_backfills = '1'
[root@ceph301 ~]# ceph config show osd.20 osd_max_backfills
1000

Any clues here? Thank you very much!
