Our current vROPS deployment consists of 1 master, 1 replica, 3 remote collector. All running vROPS 8.3 fully patched. Upgrade to vROPS 8.4 fails at stage 4 of 9 on the master node. Failure message is "FailedPAK action "run cassandra db upgrade". I have already checked admin and root account, passwords and expiration settings are fine. Plenty of space on the filesystems on all the nodes. DNS settings and NTP settings are fine as well. Any clue what could be happening?
