TrueNAS SCALE 21.04 -- iscsi/nfs crash loop

Acknowledging that TrueNAS SCALE is in alpha, I’m having trouble getting democratic-csi to work at all (freenas-iscsi, freenas-nfs, nfs-client). I’m using Rancher as a GUI for over a k3s cluster, if it makes a difference.

To just debug one problem at a time, here is my iscsi setup:

• I have installed the prerequisites on every node
• I have set up a portal and initiator on TrueNAS, and I know iscsi works fine because I have vSphere connecting to a different iscsi target using a different portal and different initator.
• I have created a csi user, provided my public key, and allowed no-password sudo on the TrueNAS CLI.

Whenever I try to create a PVC, it gets stuck in pending status. I can see that the volume gets created on TrueNas: Once in a while it will make it to bound, but then I cannot use the PVC:

Unable to attach or mount volumes: unmounted volumes=[redis-data], unattached volumes=[redis-data config redis-tmp-conf tmp redis-token-bmq9m start-scripts health]: timed out waiting for the condition
MountVolume.MountDevice failed for volume "pvc-b9269150-0a75-40e3-b1c2-6b5722904c07" : rpc error: code = Aborted desc = operation locked due to in progress operation(s): ["volume_id_pvc-b9269150-0a75-40e3-b1c2-6b5722904c07"]

However, the csi pod ends up stuck in a crashloopbackoff status.

Here’s the subset of the logs that I believe are pertinent (a huge amount of goroutine ## ... follows. I can share if required.

Quick update: The iscsi storageClass and deployment are working just fine. The nfs one is generally functional, but continuously has to restart the controller because it gets a timeout on the liveness probe. I’m going to keep monitoring, but probably won’t muck with the current config until I update truenas when the next version of SCALE releases (next week).

P.S. Just edited the title to be more descriptive if someone is searching through the issues.

I restarted the nfs service with sudo systemctl restart nfs-ganesha and things started working. I’m guessing this is some bug on the Truenas SCALE side, since running down the list of systemd services showed a bunch having errored out (like logrotate).
I should probably reboot the system, but I have to reconfigure the networking every time I do so due to another bug…
