Hi,
we have one cluster where one PG that seems to be snaptrimming forever.
It sometimes seem to hinder other PGs to on the same main OSD to snaptrim
as well.
We've synced out the OSD but it still keeps happening.
It was gone sometime in between but now it is back again with the same PG.
And the constant factor is always PG 3.c1c.
Anyone got an idea what I can do? Is it possible to "sync out and recreate"
a PG, like I can do with an OSD?
Here is some output from the pg list
Cheers
Boris
