I agree with the sentiment regarding swap, however it seems the OS devs still
suggest having a swap, even if its small. We monitor swap file usage and there
is none in the ceph clusters, I am mainly looking at eliminating it(assuming
its “safe” to do so), but don’t want to risk production machi

Hello Brent,
no, swap is definitely not needed if you configure systems correctly.
Swap in Ceph kills all your performance and brings a lot of harm to
clusters. It increases the downtime, decreases the performance and can
result in much longer recovery times which endangers your data.
