FSX OpenZFS slow volume creation

Hello everyone,

I have the following problem. I have AWS EKS cluster and I have installed aws-fsx-csi-driver and created FSx OpenZFS filesystem. My EKS StorageClass has following parameters:

• kind: StorageClass
• apiVersion: storage.k8s.io/v1
• metadata:
• name: fsx-openzfs-delete
• provisioner: fsx.openzfs.csi.aws.com
• parameters:
• ResourceType: "volume"
• ParentVolumeId: '"fsvol-XXXXXXXXXXX"'
• DataCompressionType: '"LZ4"'
• ReadOnly: 'false'
• RecordSizeKiB: '128'
• StorageCapacityReservationGiB: '1'
• StorageCapacityQuotaGiB: '-1'
• OptionsOnDeletion: '["DELETE_CHILD_VOLUMES_AND_SNAPSHOTS"]'
• reclaimPolicy: Delete
• allowVolumeExpansion: true
• mountOptions:
• • nfsvers=4.1
• • rsize=1048576
• • wsize=1048576
• • timeo=600
• • nconnect=16

wich creates Volumes inside this filesystem. Unfortunatelly the creation of the volumes when I apply PersistentVolumeClaim is very slow. It tooks around minute to create a volume. And when I need to create several, 5 or 6, volumes it tooks too much time for the creation of all of them. In addition the creation of the volumes is not paralel but sequential - one after another. This problem brakes very often my deploys.

How I can speed up volume creation if not with speed like GP2 Volumes but at least to be 2-3 times faster?

thanks
