pdcsi 0.14.9 - failed to find and re-link disk with udevadm
devoxel opened this issue · 7 comments
We are hitting a similar issue to #608 in a GKE cluster - running version 1.25.8-gke.1000
and a Spot VM nodepool. That last comment of that bug mentioned it's best to start a new bug when discussing this.
Some Background
- Probably unimportant, but for completeness, the workload is ECK. Suffice to say: it's deploys a statefulset which ended up having these issues.
- We noticed unusual behavior with the cluster yesterday, July 4th. Lots of pods were encountering NetworkNotReady events and being rescheduled. We have seen this before especially with GKE spot-vms; and in some cases had to drain the node. Didn't see that here, the pods came back up, it was just happening periodically.
- We didn't think too much about these issues. This is spot-vms so we expect to see some weirdness, and while this was worse than we've seen before; we just let it continue. Personally, I was more interested in how the workload was responding to this
- Below is a snapshot of the Events from a pod in the StatefulSet while this was ongoing.

The Bug
- Fast forward to today and things seem mostly recovered from the noise yesterday except one pod is stuck in PodInitalizing
- We see the error from the bug title

I haven't deleted the pod yet. This is a playground cluster and this sts can tolerate a single failure. I expect deleting the pod will fix the issue - but if requested I can verify this. I thought it might be more useful to keep the pod / node for direct debugging (but it's a spot VM so it could just be yanked away).
I'm also opening a support issue for this, but these things probably will move faster if I report it directly here.
I'm finding same error with version 1.28.1-gke.1066000
. We have different nodePools running similar workload and we are facing these very frequently on a nodePool running ARM instances (t2a). We found that from a statefulset of 22 replicas, most of them failed simultaneously with this error, when the PVC was expected to be expanded.
We've tried upgrading GKE version (twice) with same results. Also replacing the VMs, deleting the pods, ... does not work. Disks seems to be healthy and can be mounted on the VM.

I think in our case the issue is more related with #1398
Hi,
We had same issue this Saturday while we were upgrading the GKE to v1.27.4-gke.900
.
3 pods were failing to start due to it's PV having that error:

btw, @devoxel , restarting the pod does not help. We even tried to cordon the node where the pod was running and deleting the pod so the was scheduled to another node, but that didn't help. Same error.
As this is a Prod cluster we had no other choice that deleting the PVs and get new ones, luckily for us the data was replicated in other PVs.
Hi,
Same issue. multiple nodes in the cluster started having this error when the pods are rescheduled. Rescheduled the pods, provisioned new nodes, these PVs will not mount.

Just adding a +1 here: I've seen this, but curiously only in GKE ARM clusters.
