Discussion:
when kubelet cleanupOrphanedPodDirsit may fail when the path is a file the log is ` when can see ,this path is a file ,not a directory kubelet can delete the file and path when deleting orphaned pod kubernetes 1.20.2+docker+nvidia-dockerand the pod has GPU allocated No response <details20.5 </details<detailsnone </details<details</details<details</details<details</details<details</details
kubelet only delete dirwhen the path is file ,it will fail my pod volume is like this

Mounting a file using a subpath is fine, however I think mounting the same using twice isn't. Why do you need both? Can you try deleting and use in both places?
thanks, is this the reason for the problem?
It might be... can you do the test and confirm?
/triage needs-information let's wait for information on how things behave when not mounted twice
oki have a try

i delete cudagpu,but it still has same problem
Thanks let me come back to this soon...
Are you still using 1.20? Would it be possible to retry with a supported version of k8s, best would be 1.23?
using 1.20.
can you reproduce with 1.23? otherwise it'd be difficult to propose fixes to a k8s out of support.
ok. i will test in 1.23

Hi, we got the same issue, could someone confirm whether this issue has been fixed? we're using 1.20.7.
/reopen I am able to reproduce it with v1.29, but only with dirty hacks. Something bad must happen during node reboot. a Pod that uses a CSI volume + file on the volume as a subpath. kubelet service on the node where the pod runs. -delete the Pod. remove from the pod local volume directory, i.e. . I don't know how to reproduce the issue without this step. How else can it happen that the file gets missing or its reconstruction fails?! reboot the machine.

After reboot, newly started kubelet will not see the Pod in the API server, and it will try to reconstruct its CSI volume mount from That file is missing, and therefore it will declare the volume as unmounted and cleaned, without cleaning its subpaths. The orphan cleanup routine will then try to remove subpaths of the volume, but it can handle only directories as subpath, not files -will fail.
Reopened this issue. <detailsIn response to : /reopen Stop kubelet service on the node. Force-delete the Pod. Manually remove from the pod local volume directory, i.e. .
