  • 1.  NAS Datastore failure

    Posted Aug 25, 2023 03:16 PM

    We currently have a cluster of 3 esxi 6.7 hosts managed through vSphere. When mounting our NAS appliance as an additional datastore through nfs we see it succeed on Server3 but fail on Server1 and Server2 due to both servers being unable to resolve the Hostname. This NAS has worked previously with the same network path and the same folders. We've tried looking at the hosts file along with the host.conf and resolv.conf files as well as trying to attach the datastore directly from the esxi server's web client and from an ssh session in the esxi host

    Hey  ,

     

    looks like a DNS issue, Check: 

    • On Server1 and Server2, ensure that the DNS settings are correctly configured
    • From the ESXi host's SSH session, try to resolve the hostname of the NAS appliance using the nslookup or ping command:

     

    nslookup nas_hostname 

ping nas_hostname

     

    • Ensure that the hostname resolves to the correct IP address. If it doesn't, there might be a DNS issue.
    • try restarting the management network on Server1 and Server2.

     

    /etc/init.d/hostd restart

/etc/init.d/vpxa restart

     

    • Clear the DNS cache on Server1 and Server2:

     

    /etc/init.d/nscd restart

    Hello  ,

    We were able to connect the datastore using the ip address in place for the host name. More of a workaround rather than a solution but we'll definitely make sure to follow through with the troubleshooting steps mentioned as well just to be safe.

    If you used IPs instead of hostnames its another indication of something wrong with DNS
