Installation issues
Use the troubleshooting tips and tricks in IBM Fusion installation.
Note: To log in to the provisioner node, as a kni user, SSH to service node. It is the same host
that the IBM Service Support Representative (SSR) provided you before the stage 2 of the
installation:
https://<host IP address>:3000/isfsetup. For the actual step, see
Installation procedure. - You might observe unpredictable Red Hat®
OpenShift® Container Platform cluster degradation issues that include
but not limited to severe performance and operator degradation issues. To avoid these issues, go
through the Red Hat recommendations. For example,
the following list has some of the high-level considerations (not all inclusive):
- Your cluster must have sufficient CPU and RAM resources that are allocated to etcd and compute nodes.
- The etcd disks must be high-performing with low read or write latency and high IOPs. You can use FIO test to check IOPS for etcd disks.
- There must not be high network latency among etcd members.
- If you notice that the operator installation or upgrade fails with
DeadlineExceeded error, see Operator installation or upgrade fails with DeadlineExceeded error.
