So you are not upgrading the kernel, you are upgrading the OS.
Sorry Daemeon, my bad. I meant the OS :-)
So what would you recommend, replace a node with a new OS node
with -Dcassandra.replace_address (never tried it before), or try to format
the root directory of the existing node, without
So you are not upgrading the kernel, you are upgrading the OS. Not what
you asked about. Your devops team is right.
However, Depending on what is using python, the new version of python may

We've done such in-place upgrade in the past but not for a real production.
However you're MISSING the point. The root filesystem along with the entire

No.

Hi All,
Hypothetically speaking, let's say I want to upgrade my Cassandra cluster,
but I also want to perform a major upgrade to the kernel of all nodes.
In order to upgrade the kernel, I need to reinstall the server, hence lose
