Hello,
how is the best way to change all nodes root password (SSH) and web interface admin password?
Will a cluster crash if I change them?
Greets,
Andreas

You can change the ui password for admin user from the ui
for ssh login: both rsa key and password are allowed, PetaSAN only uses password when a node is joining a cluster, after this it copies the rsa key and all inter-node management is done using ssh key, so you should be able to change root password on each node without issue. It may be possible to change the rsa keys as well, but there could be management calls working in the background that may temporarily fail, like if you are grabbing disk information in the ui disk list, but they will not be critical failures leading to i/o interruption or crashes.
