Zhenshi, I've been doing the same periodically over the past couple weeks. I haven't had to do it a second time on any of my OSDs, but I'm told that I can expect to do so in the future. I believe that the conclusion in this list was that for a workload with many small files it might be necessary to allocate 300GB for DB per OSD. -Dave -- Dave Hall Binghamton University kdhall@binghamton.edu On Mon, Nov 16, 2020 at 12:41 AM Zhenshi Zhou <deaderzzs@gmail.com> wrote:

well, the warning message disappeared after I executed "ceph tell osd.63 compact".

Has anyone met this issue yet?

Hi,

I have a cluster of 14.2.8. I created OSDs with dedicated PCIE for wal/db when deployed the cluster. I set 72G for db and 3G for wal on each OSD.

And now my cluster is in a WARN stats until a long health time. # ceph health detail HEALTH_WARN BlueFS spillover detected on 1 OSD(s) BLUEFS_SPILLOVER BlueFS spillover detected on 1 OSD(s) osd.63 spilled over 33 MiB metadata from 'db' device (1.5 GiB used of 72 GiB) to slow device

I lookup on google and find https://tracker.ceph.com/issues/38745 I'm not sure if it's the same issue. How can I deal with this?

THANKS
