This is in part a question of *how many* of those dense OSD nodes you have. If
you have a hundred of them, then most likely they’re spread across a decent
number of racks and the loss of one or two is a tolerable *fraction* of the
whole cluster.
If you have a cluster of just, say, 3-4 of

Thanks Paul. I was speaking more about total OSDs and RAM, rather than a single
node. However, I am considering building a cluster with a large OSD/node count.
This would be for archival use, with reduced performance and availability
requirements. What issues would you anticipate with a large

you can manually trigger a compaction via the admin socket (or was it

I have one or two more stability issues I'm trying to solve in a
cluster that I inherited that I just can't seem to figure out. One
issue may be the cause for the other.
This is a Jewel 10.2.11 cluster with ~760 - 10TB HDDs and 5GB journals on SSD.
