[UnRAID 6.9.2] Unraid server is resolving "SERVER" to incorrect ip address after update


Recommended Posts

I have run into an odd issue after updating my Unraid servers from 6.8.3 to 6.9.2. The issue presented as my secondary server failing to mount the remote share I use in my backup script and has been traced to the name 'SERVER' resolving to an incorrect ip address 172.30.1.100. 

 

Primary Server Name = SERVER   Primary Server IP = 192.168.1.100

Secondary Server Name = BACKUP   Secondary Server IP = 192.168.1.110

 

root@backup:~# ping SERVER

PING SERVER (172.30.1.100) 56(84) bytes of data.
--- SERVER ping statistics ---
2 packets transmitted, 0 received, 100% packet loss, time 1005ms

 

If I modify the mount commands to use the ip address instead of the server name it works properly. Originally I thought this was an issue with Unassigned Devices but can duplicate the behavior with krusader as well.


Other devices on my network can ping by name successfully and there are no 172.30.x.x addresses in my environment.
