July 1, 20251 yr Hi all,I'm running Unraid 7.1.4 and have encountered a recurring issue where my shares intermittently disappear. This, in turn, causes broader problems, such as breaking all Windows network shares and virtiofs mounts used within Unraid-hosted VMs, most notably my Proxmox Backup Server.The issue temporarily resolves if I reboot the NAS, but it typically reoccurs within minutes to a few hours.I've attached a screenshot showing the shares list completely empty, along with two sets of diagnostic logs: one captured during the issue, and another taken post-reboot when the shares were accessible again, for comparison.If anyone has any insight into what's causing this or how to fix it, I’d greatly appreciate it. Ironically, the problem only began after I upgraded from a trial licence to an Unleashed licence.Thanks in advance.pre-reboot - urd-diagnostics-20250701-1117.zip post-reboot - urd-diagnostics-20250701-1134.zip Edited July 1, 20251 yr by Sanjiyan

Since none of my shares have NFS exports, I have disabled the NFS service.Is this a known issue/bug? If so, I wonder when they plan to patch it. Edited July 1, 20251 yr by Sanjiyan

To be honest, I'm still unclear on the root cause. I simply disabled the NFS service, as I don't currently use it, and doing so has stopped the issue from affecting me, for now. As for whether it might return in future, I’m not sure.

August 11, 2025Aug 11 this issue just happened to me on 7.1.4. i am not using nfs (is disabled), and im only using smb. My shares show blank, but i can still access /mnt/cache and /mnt/Disk2 via smb rootshare. /mnt/user, /mnt/disk1, etc show as blank via the share. reboot does not help.I also do NOT see "shfs: shfs: ../lib/fuse.c:1451: unlink_node: Assertion `node->nlookup > 1' failed." in my logs as others have reported. Any ideas?Thanks,JD Edited August 11, 2025Aug 11 by JudasD

I still do not know how this permission change occurred. Once i set /mnt/disk1 to 0777 to match the others, everything went back to normal. Symptoms:0333 caused all shares to disappear from the UI page. Array shares where not showing AND did not operate. pool shares were also NOT showing, but did operate.via SMB: /mnt/user, /mnt/user0 and /mnt/disk1 all showed empty. all other paths would show correct folder items.I can now go about my day and put down the ant-acids. :)Thanks,JD
