I have installed MongoDB Enterprise Kubernetes Operator using this steps
When tried to add different storageClass for data and journal volumes on shard members. I want to add xfs file system for data volume. so created below storage class:
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: mongo-data-xfs
provisioner: kubernetes.io/aws-ebs
parameters:
type: io1
iopsPerGB: "10"
fstype: xfs
encrypted: "true"
reclaimPolicy: Retain
allowVolumeExpansion: true
my sharded cluster deployment looks like this:
apiVersion: mongodb.com/v1
kind: MongoDB
metadata:
name: ct-sharded-cluster
spec:
shardCount: 1
mongodsPerShardCount: 3
mongosCount: 1
configServerCount: 1
version: 4.2.2-ent
opsManager:
configMapRef:
name: shard-cluster-config
# Must match metadata.name in ConfigMap file
credentials: ops-manager-api
type: ShardedCluster
persistent: true
shardPodSpec:
cpuRequests: 500m
cpu: 500m
memoryRequests: 1G
memory: 1G
persistence:
multiple:
data:
storage: 5G
storageClass: mongo-data-xfs
journal:
storage: 2G
storageClass: mongo-beside-data
logs:
storage: 2G
storageClass: mongo-beside-data
No when i deploy this cluster in my operator, journal and logs pods are coming up because it is is fsType=ext4, data volume is coming up, it stuck in ContainerCreating state always. if i describe particular pod, got this failed volume mount message:
Warning FailedMount 30m (x300 over 13h) kubelet, ip-10-0-23-43.ec2.internal Unable to mount volumes for pod “test-cluster-0-0_mongo-operator(385f92e8-07e3-460f-af48-b80c4fe28e45)”: timeout expired waiting for volumes to attach or mount for pod “mongo-operator”/“test-cluster-0-0”. list of unmounted volumes=[data]. list of unattached volumes=[data journal logs mongodb-enterprise-database-pods-token-kdhvp]

Any one tried fsType=xfs
volume of ebs provisoner in k8s? Any help appreciated.
Thanks.
