TrueNAS system info:
CPU: Intel(R) Xeon(R) Gold 5120
RAM: Micron 36ASF2G72PZ-2G1A2 DDR4 16384MB 2133MHz ((x6) 96GB)
Model: Tyan GT86C (unmodified)
TrueNAS Community Edition (Scale) v25.04.2.6 (bare metal)
Client system info:
- Ubuntu server v24.04.3 LTS (GNU/Linux 6.8.0-88-generic x86_64) (VM running on Proxmox v6.8.12-11-PVE)
- Proxmox host ((for backups, iso, more) is also experiencing the same NFS disconnections).
I have been dealing with NFS shares working, then disconnecting periodically (I am seeing no pattern as of now), but will sometimes resume without completely rebooting a client or the share itself. NFS-common is installed on the client, too. SMB & iSCSI have been working fine without issues. Sometimes it will restore without intervention (can take 5 minutes to hours), require a reboot on the client (a hard reset in my case because the system locks up because of qBittorrent not done sending data), disabling and reenabling NFS on TrueNAS, or in extreme cases, a reboot for the client and TrueNAS.
What I have done:
- Reinstalled TrueNAS & Ubuntu (client) & restored my config
- Used different clients (including a fresh Ubuntu install)
- Tried using NFSv3
- Rebooted everything (router and all)
- Monitored network ping from client to TrueNAS server (no issues)
- Update everything
That Ubuntu client only has Podman, Portainer, Gluetun, qBittorrent, & any required things for those to run.
Mount settings on the Ubuntu client:
10.10.0.156:/mnt/<truenas mount point> /home/administrator/<mount point> nfs rw,hard 0 0
I have attached dmesg logs from the client and TrueNAS kernel logs. I also want to note, if I use SMB/CIFS on the same client, I will have issues with it on Ubuntu server v24.04.3 LTS, but I have no issues on my Windows client (bare metal) with SMB.
