03/14/2023, 8:42 AMIs there some way to disable NFS support in Longhorn to improve stability?

03/14/2023, 9:53 AMCan you elaborate more on your question?

03/14/2023, 3:08 PMAgain and again Longhorn stalls with "nfs server not responding". See my posting of yesterday. I would like to disable Longhorn's RWX in favor of the old nfs-provisioner and a dedicated NAS.

03/14/2023, 3:09 PMDo you have RWX volumes in your longhorn cluster?
BTW, what’s the Longhorn version you’r using?
c
crooked-cat-21365
03/15/2023, 6:47 AMYes, there are RWX volumes, but they can be removed. Longhorn is version 1.4.0, installed via the longhorn-crd-101.2.0+up1.4.0 and longhorn-101.2.0+up1.4.0 helm charts in Rancher.

03/15/2023, 6:49 AMA little confused. If you don’t want to use the Longhorn RWX volumes. Why not just use the old nfs-provisioner instead rather than create RWX volumes?
c
crooked-cat-21365
03/15/2023, 7:43 AMBecause longhorn is the default storage class for all access modes. I have only limited control over which storage classes my colleagues use. I just don't want to provide longhorn as a default for RWX anymore.

03/16/2023, 1:29 AMBTW, do you experience the
nfs: server 10.43.170.7 not responding, timed outAnd what’s your worker node’s OS version?
Because longhorn is the default storage class for all access modes. I have only limited control over which storage classes my colleagues use. I just don’t want to provide longhorn as a default for RWX anymore.There is no way to disable the Longhorn RWX. I think we can investigate the NFS version not responding issue and see if there is any issue in the OS layer. Do you know how to reproduce this issue and can you help provide more information of your cluster? Thank you.

03/16/2023, 8:25 AMI haven't found a reliable way to reproduce this problem, yet. By now it came up just a few times. If an NFS server pod dies for whatever reason, is it restarted or replaced?
i
icy-agency-38675
03/16/2023, 8:29 AMGot it.
NFS server pod died issuec

03/16/2023, 8:44 AMGood to know. I have found #5456 on github, but I am not sure if this is the correct issue.
i
icy-agency-38675
03/16/2023, 8:45 AMYeah, that’s it.
c
crooked-cat-21365
03/16/2023, 9:28 AMAre you sure it has been fixed for 1.4.1? It was closed 3 days ago. Milestone is 1.5.0.
i
icy-agency-38675
03/16/2023, 9:29 AMYeah, it is backported.
