eagle470 Posted August 8, 2023 Share Posted August 8, 2023 I have an all flash/all nvme zfs disk pool that I have a nfs share presenting out to an ESXi host for a work/homelab project I'm doing. The NFS mount keeps dropping and I cannot figure out why. Hopefully there is something in the logs. beast-diagnostics-20230808-0848.zip Quote Link to comment
dlandon Posted August 8, 2023 Share Posted August 8, 2023 It's difficult for us to help you since LT does not support anything associated with ESXI and we don't know much about it. Since ESXI is mounting Unraid shares with NFS, it would be best to loook at the ESXI for answers. One thing to confirm is that ESXI is mounting the shares with NFSv4. I saw in your log where NFSv4 was being used on a share, so maybe that's not a problem. In general the reliability of NFS connections are affected by the followng: Version of NFS being used. Networking issues. Robust NFS requires a solid network. Options used when mounting NFS clients can affect the reliability of the connection and error recovery. Quote Link to comment

ESXi is mounting the share with nfs 4.1, that much I know for sure, it works for a while, as long as I'm actively doing stuff it seems to stay connected, but once I walk away for the night and it's just running, even with a vm on it, it seems to time out.

eagle470 Posted August 8, 2023 Author Share Posted August 8, 2023 (edited) I did drop a question over on vmware's community forums. https://communities.vmware.com/t5/Cloud-SDDC-Members/NFS-MOUNT-PRESENTED-TO-ESXI-KEEPS-DROPPING/m-p/2981374#M217 Edited August 8, 2023 by eagle470 Quote Link to comment
eagle470 Posted August 8, 2023 Author Share Posted August 8, 2023 the issue is that I'm doing an rsync to that server to copy data to it. I'm consuming the entire 10Gb of that server's NIC. https://communities.vmware.com/t5/Cloud-SDDC-Members/NFS-MOUNT-PRESENTED-TO-ESXI-KEEPS-DROPPING/m-p/2981453/highlight/false#M218 Quote Link to comment
