With two CVMs unavailable, there are now two sets of physical disks that are inaccessible. You didn’t specify if you were on AHV or ESXi, they have different troubleshooting methods, but I would start by noting the configuration and test results of each component and start eliminating things at various layers… I’ve seen how a simple miss-configuration on either side (gateway or cluster) could cause this. Nutanix port diagram for storage services Nutanix network port diagram for Nutanix Files Nutanix Files network port diagram Port Description. Are there any ACLs on the gateway with respect to the VLANs where CVMs/Hosts are? Education Nutanix Certification 217; In The Lab HomeLab Setup 64; Global Forums Forum Français 2 日本語フォーラム 97; Archive Archive 0; Blog ; Ideas ; User Groups ; Product Updates ; Create topic; Login; Solved Prism Central - Server is not reachable error? Attach the files at the bottom of the support case on the support portal. Cause: Directory with same name as VM name … An administrator needs to expand a Nutanix cluster that is tagging the network traffic at the CVM and AHV level. I’m at a complete loss. In other solutions, where the storage stack is not independent, a failure or a kernel panic could potentially force Guest VMs and applications to have to be restarted in a different host, causing serious application outages. If you find that a host in your cluster is unreachable over the network but IPMI console shows a prompt similar to the one below, then you are in the Phoenix Shell. If the check reports a FAIL status indicating that Nutanix Files Server is unreachable, ensure through Prism that all Nutanix Files VMs are up and running. In this case NDFS Autopath will also redirect the storage path to another CVM. Nutanix web console shows one CVM to host connectivity is failed. Alerts List. Ensure that physical networking, VLANs, and virtual switches are configured correctly. Nutanix Files Deployment Error: DGW Ip Unreachable. 2 years ago 19 November 2018. Ansible communicates with client computers through SSH, so each server you want to manage should be accessible from the Ansible server by typing: The beginning was fine, but after few minutes I noticed that one of the CVM upgrade is failing at 93% and the process was restarting: After this was repeated several times I realized that there is something wrong. Resolution: To resolve the Unreachable DNS server can prevent 2 node clusters from starting services after failure – check the DNS / Name server entry in CVM configuration file and check connectivity. This behavior is very important as it defines Nutanix architecture resiliency, allowing Guest VMs to keep running even when there is a storage outage. NDFS is also self-healing meaning it will detect the CVM has been powered off and will automatically reboot or power-on the local CVM. x.x.x.1 : 0.187 ms. x.x.x.2 : Unreachable. Guest VMs on this host may appear to “hang” until the storage path is restored. This is quick overview, in no way it is complete in what other stats we can get. More importantly, however, is the additional risk to guest VM data. From Nutanix Prism you can manage single Nutanix … nutanix@CVM$ ncc health_checks fileserver_checks fileserver_cvm_checks file_server_status_check. 4) Pick up any host and shutdown the running VM’s and the CVM ( Please keep in mind , you can shutdown only one CVM at a time). Nutanix has discovered certain conditions in AOS 5.5.x release where tomcat will fail heartbeats and once this happens 3 consecutive times, the service will restart. Impact: Storage may be unavailable and/or performance issues may be observed. Attach the files at the bottom of the support case on the support portal. Increase the cloud CVM size. Verify that the NTP server returns a valid and accurate response. With Nutanix, it is a breeze, because it is a converged platform and Nutanix is VM aware in addition to statistics, Nutanix localizes data based on where the VM is accessing data from. Lately, a wrong gateway was entered during the initial setup of a Nutanix cluster. In our case we noticed there was unreachable on one of the CVM’s. Open a Virtual Console through Prism Element 4. The only thing I can think of is that the DFW does not respond to ping, is that required? This leaves room to add … The performance may decrease slightly, because the IO is now traveling across the network, rather than across the internal virtual switch.

If the CVM on the host the VM(s) are registered on was shutdown or rebooting, retry the snapshot operation. Removing Unreachable Or Powered Off Node From Nutanix Cluster Versions affected 4.1.x Description. With all of Nutanix certification NCA-5.15 exam dumps questions, you can prepare and study the test well. 5) Then drag & drop the host to the Cluster , the host will be added to the cluster without any hassle. A boot drive failure will eventually cause the CVM to fail. Nutanix cluster / CVM runs hundreds of services to run and maintain the cluster, but what will happen when Nutanix cluster / CVMs services goes down. phoenix / # If Phoenix was created with Foundation 4.3 or later, the prompt will appear as follows. In parallel, NDFS is constantly monitoring the SSDs to predict failures (I’ll write more about it in the future). Check the minerva_cvm.log (CVM’s /home/nutanix/data/logs folder) for any additional hints for issues. The alias is just a name to refer to that server. 4. When local data is available, the optimal path is always through the local CVM to local storage devices. 9. How can an administrator access a Windows VM running on a Nutanix cluster if it is unreachable via ping? # Login to Controller… CVM ip address is unreachable [103088] [A103088] Name: Inter-CVM connectivity check: Description: Check that all CVMs are reachable via ping. 2020-03-18 08:53:20 CRITICAL 54229584 decorators.py:47 Traceback (most recent call last):   File "/home/jenkins.svc/workspace/postcommit-jobs/nos/euphrates-5.10.9.1-stable/x86_64-aos-release-euphrates-5.10.9.1-stable/builds/build-euphrates-5.10.9.1-stable-release/minervacvm-python-tree/bdist.linux-x86_64/egg/util/misc/decorators.py", line 41, in wrapper   File "/home/jenkins.svc/workspace/postcommit-jobs/nos/euphrates-5.10.9.1-stable/x86_64-aos-release-euphrates-5.10.9.1-stable/builds/build-euphrates-5.10.9.1-stable-release/minervacvm-python-tree/bdist.linux-x86_64/egg/minerva/cvm/server.py", line 154, in __serve_http   File "/home/jenkins.svc/workspace/postcommit-jobs/nos/euphrates-5.10.9.1-stable/x86_64-aos-release-euphrates-5.10.9.1-stable/builds/build-euphrates-5.10.9.1-stable-release/minervacvm-python-tree/bdist.linux-x86_64/egg/util/net/wsgi_utils.py", line 114, in wsgi_gevent_server_create   File "/home/jenkins.svc/workspace/postcommit-jobs/nos/euphrates-5.10.9.1-stable/x86_64-aos-release-euphrates-5.10.9.1-stable/builds/build-euphrates-5.10.9.1-stable-release/minervacvm-python-tree/bdist.linux-x86_64/egg/util/net/wsgi_utils.py", line 54, in create_socket   File "", line 1, in bind error: [Errno 98] Address already in use, But I’ve changed addresses specified and still get exactly the same errors, Hello @S.Riser  I tried the same in my lab environment, if the G/W IP is not reachable, it won’t let you create a FS.
