K8ssandra pods take 15min to be ready

I am running k8ssandra 1.4.1 on a 3 nodes K3s cluster.
When I reboot all the K3s cluster nodes, the cassandra pods take about 15min to be ready, while all other pods are ready in few seconds.
Is there a way to speed up the readiness of the cassandra pods?

15 minutes does seem like a long time. What kind of storage are you using?

Cassandra is on NVMe disks and network connection between nodes is 25Gb.
I have reproduced the same behavior on a number of K8s and K3s clusters, even on a single-node cluster.
