for pv, lens not reflecting true K8 state but kubectl does #3301

Open papillon88 opened 3 years ago

papillon88 commented 3 years ago

Using LENS 5.0.2. But I experienced the issue even with 4.2.4 After deleting the PV using kubectl. kubectl shows no PV : image (7) But Lens still shows PV is active : image (8) I've waited to 3-4hrs for the GUI to refresh automatically, but I still see the PV in the GUI. I have to restart Lens everytime to refresh the GUI to reflect the true K8 state. Please have a look. Thanks

Also Ctrl + R solves the issue sometimes on windows - but most of the times Ctrl + R indefinitely freezes the entire Lens GUI and as a result I have to shutdown Lens and restart it

Hi, can you provide some logs from the Developer Tools console?

I see the same problem with 5.0.2-latest (20210705.2) using NetApp Trident CSI with SolidFire iSCSI back-end and K8s v1.21.2 (Ubuntu 20.04).

In my case with Lens on Ubuntu 20.04, CTRL+R helped me refresh and update ghost PVs, making them disappear. But later it crashed /persistent-volumes app (crash log can be found at the bottom of this comment).

Interestingly, on the second try it was PVC that got stuck in the Lens UI, while the PV was properly cleared when kubectl del pv was executed. It appears that what happens depends on timing. For example, if I execute create PVC/delete PVC very quickly, I don't end up with ghost PVs (or PVCs).

On the third try I got the previous behavior, where a PV remained in Lens after its PVC was deleted. I don't know how, but there was an error in the red-colored response (see screenshot):

{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {

  },
  "status": "Failure",
  "message": "persistentvolumes \"pvc-0cc7c1cd-fea0-4765-b6cc-07ed177b9a3a\" not found",
  "reason": "NotFound",
  "details": {
    "name": "pvc-0cc7c1cd-fea0-4765-b6cc-07ed177b9a3a",
    "kind": "persistentvolumes"
  },
  "code": 404
}

I don't know what I did to get that error appear in the log.

Later, JSON responses became correct (empty), but the UI was still showing the ghost PV:

{
  "kind": "PersistentVolumeList",
  "apiVersion": "v1",
  "metadata": {
    "resourceVersion": "17491424"
  },
  "items": []
}

In Console I noticed this:

When trying to manually delete the ghost PV:

When I pressed CTRL+R this time (with Debug Console open), it crashed /persistent-volumes.
