What steps did you take and what happened:
A large number of similar errors in the logs of zfs-localpv-node pod.

I'm not 100% sure, but it seems to me that the error is related to the fact that there are too many requests to change the "zfsnodes.zfs.openebs.io" resource. (constantly changes the amount of free disk space)
Perhaps it depends on the load of the system.

What did you expect to happen:
No such errors.

The output of the following commands will help us better understand what's going on:
(Pasting long output into a GitHub gist or other Pastebin is fine.)

Anything else you would like to add:
[Miscellaneous information that will assist in solving the issue.]
Environment:

  • ZFS-LocalPV version: chart: zfs-localpv-1.9.7 appVer: 1.9.1
  • Kubernetes version (use kubectl version): v1.24.8+k3s1

Hi @Subetov. Does this issue still persist? Were there instances of manual changes to any of the ZfsNode CustomResources?
