Easiest way I know would be to use $ ceph tell osd.X compact This is what cures that whenever I have metadata spillover. Reed

Hello,

i added a db device to my osds running nautilus. The DB data migratet over some days from the hdd to ssd (db device).

But now it seems all are stuck at: # ceph health detail HEALTH_WARN BlueFS spillover detected on 8 OSD(s) BLUEFS_SPILLOVER BlueFS spillover detected on 8 OSD(s) osd.0 spilled over 128 KiB metadata from 'db' device (12 GiB used of 185 GiB) to slow device osd.1 spilled over 3.4 MiB metadata from 'db' device (12 GiB used of 185 GiB) to slow device osd.2 spilled over 128 KiB metadata from 'db' device (12 GiB used of 185 GiB) to slow device osd.3 spilled over 128 KiB metadata from 'db' device (12 GiB used of 185 GiB) to slow device osd.4 spilled over 128 KiB metadata from 'db' device (12 GiB used of 185 GiB) to slow device osd.5 spilled over 128 KiB metadata from 'db' device (12 GiB used of 185 GiB) to slow device osd.6 spilled over 128 KiB metadata from 'db' device (12 GiB used of 185 GiB) to slow device osd.7 spilled over 128 KiB metadata from 'db' device (12 GiB used of 185 GiB) to slow device

any idea how to force ceph to move the last 128kb to the db device?

Nobody who has an idea? Ceph automatically started to migrate all date from the hdd to the ssd db device but has stopped at 128kb on nearly all osds. Greets, Stefan Am 02.03.20 um 10:32 schrieb Stefan Priebe - Profihost AG:
