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.
Cheers
Toby
