EKS Cluster Creation Failure
There are several problems that could lead to cluster creation failure. If you see some errors when creating your cluster using eksctl, please open the CloudFormation console and check your stacks. To recover from failure, you need to follow the guidance from the eksctl output logs. Once you understand the root cause of your failure, you can delete your cluster and rerun ${KUBEFLOW_SRC}/scripts/kfctl.sh apply platform.
Common issues:
- The default VPC limit is 5 VPCs per region
- Invalid command arguments

FSX Mount Failure
Mounting command: mount
Mounting arguments: -t lustre fs-0xxxxx2a216cf.us-west-2.amazonaws.com@tcp:/fsx /var/lib/kubelet/pods/224c2c96-5a91-11e9-b7e6-0a2a42c99f84/volumes/kubernetes.io~csi/fsx-static/mount
Output: mount.lustre: Can't parse NID 'fs-0xxxxx2a216cf.us-west-2.amazonaws.com@tcp:/fsx'
This mount helper should only be invoked via the mount (8) command,
e.g. mount -t lustre dev dir
usage: mount.lustre [-fhnvV] [-o <mntopt>] <device> <mountpt>
<device>: the disk device, or for a client:
<mgsnid>[:<altmgsnid>...]:/<filesystem>[/<subdir>]
<filesystem>: name of the Lustre filesystem (e.g. lustre1)
<mountpt>: filesystem mountpoint (e.g. /mnt/lustre)
-f|--fake: fake mount (updates /etc/mtab)The Amazon FSx dnsName is incorrect, you can delete your pod using this persistent volume claim. The next step is to delete the PV and PVC. Next correct your input and reapply the PV and PVC.
kubectl delete pod ${pod_using_pvc}
ks delete default -c ${COMPONENT}
ks param set ${COMPONENT} dnsName fs-0xxxxx2a216cf.fsx.us-west-2.amazonaws.com
ks apply default -c ${COMPONENT}Feedback
