I have seen significant increases (1GB -> 8GB) proportional to number
of inodes open, just like the MDS cache grows. These went away once
the stat-heavy workloads (multiple parallel rsyncs) stopped. I
disabled autoscale warnings on the metadata pools due to this
fluctuation.

we just recently upgraded our cluster from luminous 12.2.10 to nautilus
14.2.1 and I noticed a massive increase of the space used on the cephfs
metadata pool although the used space in the 2 data pools basically did
not change. See the attached graph (NOTE: log10 scale on y-axis)
Is there any

OK, but then I'm not sure I understand why the increase was not sudden

Nautilus properly accounts metadata usage, so nothing changed it just
shows up correctly now ;)

Hi,
we just recently upgraded our cluster from luminous 12.2.10 to nautilus
14.2.1 and I noticed a massive increase of the space used on the cephfs
metadata pool although the used space in the 2 data pools basically did
not change. See the attached graph (NOTE: log10 scale on y-axis)
