i got two rancher cluster (deployed on vsphere). one with centos7 as base os and one with rancheros 1.55 (deployed via rancher ui w/ vsphere provider). on the centos7 based cluster trident integration
installation w/;
kubectl create ns trident
./tridentctl install -n trident --kubelet-dir=/opt/rke/var/lib/kubelet --csi
./tridentctl -n trident create backend -f backend-ontap-nas-mc.json
kubectl create -f sample-input/storage-class-basic-ontap.yaml
on centos7 with installed nfs-utils it is working. but on rancheros 1.55 it is not. what I installed on all nodes on rancheros is:
sudo ros service enable kernel-extras
sudo ros service enable kernel-headers
sudo ros service enable kernel-headers-system-docker
sudo ros service enable volume-nfs
sudo ros service enable volume-cifs
and I can mount a pv which was created with trident on the working centos7 cluster on a racnheros node w:
mount -t nfs4 -o soft 10.31.102.168:/trident_pvc_09666bb0_e581_4945_800a_5cb850461332 /mnt/ /mnt/
but if I deploy applications in the rancheros cluster I still git the follwing errors:
