Re: CephFS metadata pool size

I'm quite sure that this could result in the impact you're seeing. To confirm that suspicion you could stop deleting and wait a couple of days to see if the usage stabilizes. And if it does, maybe delete less files at once or so to see how far you can tweak it. That would be my approach.

Zitat von Lars Köppel <lars.koeppel@xxxxxxxxxx>:

We have been using snapshots for a long time.
The only change in usage is that we are currently deleting many small files
from the system. Because this is slow (~150 requests/s) this is running for
the last few weeks. Could such a load result in a problem with the MDS?

I have to ask for permission to order more drives. This could take some
time.

Downgrading isn't supported, I don't think that would be a good idea.
I also don't see anything obvious standing out in the pg output. Any
chance you can add more OSDs to the metadata pool to see if it stops
at some point? Did the cluster usage change in any way? For example
cephfs snapshots which haven't been used before or something like that?
