Hi In the last couple of weeks we've been getting BlueFS spillover warnings on multiple (>10) osds, eg BLUEFS_SPILLOVER BlueFS spillover detected on 1 OSD(s) osd.327 spilled over 58 MiB metadata from 'db' device (30 GiB used of 66 GiB) to slow device I know this can be corrected with a 'ceph tell osd.$osd compact' or ignored with "bluestore_warn_on_bluefs_spillover=false", but my concern is that these warnings have only recently started. Could this be a sign of something nasty heading our way that I'm not aware of? Is there a performance penalty by just ignoring, rather than compacting? Many thanks for any pointers.
