BUT, i create pod with pvc and i have a problem,
In pods logs i see the following

MountVolume.SetUp failed for volume "pvc-7815c841-361f-4f7d-8ca1-a7e2dd06fea1" : rpc error: code = Internal desc = NodePublishVolume failed for pvc-24f506d3-7ef8-4219-901b-801cab7f6dda: failed to stat source device: stat : no such file or directory

In second pod

Multi-Attach error for volume "pvc-7815c841-361f-4f7d-8ca1-a7e2dd06fea1" Volume is already used by pod(s) nginx-test-1-7c8699d678-972rn

But I also tried to create a pod with 1 replication, the same error with mounting

Status also changed in linstor

And another moment, if I do placementCount: "2"
Then when creating pvc I see this

Seems that DRBD is not set up correctly on the k8s nodes. Please check "linstor node info" and verify that DRBD is actually supported on the k8s nodes. You might also verify that DRBD 9 is loaded instead of 8.4 by checking /proc/drbd on the k8s nodes.

It should work, but something is blocking the LINSTOR Satellite on the k8s node from setting up the DRBD device. Are there any error reports related to the resource (linstor error-report list + linstor error-report show <id>)?

Seems like the issue is:

pvc-47dde43d-3385-4810-b181-d9d498022e9a: Failure: (146) VERIFYAlgNotAvail
additional info from kernel:
failed to allocate crct10dif-pclmul for verify

I believe LINSTOR should automatically select the right verify algorithm useable by all nodes. What kind of kernels / host OS are you using? Seems like you use very different versions that might not have any algorithms in common.

i upgrade kernel on k8s nodes to 5.15.104, the same version on linstor cluster
But now drbd is not version 9

root@aisk8swr01t:~# modprobe drbd
root@aisk8swr01t:~# cat /proc/drbd
version: 8.4.11 (api:1/proto:86-101)
srcversion: 98E710E58B3041F3046305B
root@aisk8swr01t:~# apt list --installed | grep drbd
drbd-dkms/unknown,now 9.2.3-1 all [installed]
drbd-utils/unknown,now 9.23.1-1 amd64 [installed]

You can try running dkms build drbd/9.2.3-1, but this should actually be done automatically when you install a new kernel ☹️

I brought to the same version of the kernel and drbd on all nodes
But still, when connecting to the pod to the pvc, I see

kubectl describe
