Gluster users - Mar 2021 - Gluster usage scenarios in HPC cluster management

The stuff I work on doesn't use containers much (unlike a different
system also at HPE).

Leaders are over-sized but the sizing largely is associated with all the
other stuff leaders do, not just for gluster. That said, my gluster
settings for the expanded nfs tree (as opposed to squashfs image files on
nfs) method use heavy caching; I believe the max was 8G.

I don't have a recipe, they've just always been beefy enough for
gluster. Sorry I don't have a more scientific answer.

By "pods" I meant "glusterd instance", a server hosting a
collection of
bricks.

Seems that 64GB RAM are not enough for a pod with 26 glusterfsd
instances and no other services (except sshd for management). What do
you mean by "beefy enough"? 128GB RAM or 1TB?
