Cluster name must be in FQDN format

While attempting to upgrade from v4.7.1 to v5.x.x, the pre-upgrade fails with the following error: "Cluster name must be in FQDN format." Is there a way to upgrade the name from "CLUSTER" to "CLUSTER.domain.com" without downtime? Or, alternatively, is there a way to perform the upgrade without making this change/ingoring this message? Thanks all!

Incompatibility with Server 2016/Win10 and 2012r2 Hyper-V Cluster (AOS: v4.7.1)

AOS: v4.7.1 Server Platform: Multiple Hyper-V (2012 r2) clusters It appears that if you whitelist an IP that belongs to either a Server 2016 or a Windows 10 machine, that machine still can not access the SMB share being published by our Nutanix (v4.7.1) clusters. We found this out after upgrading our SCVMM server to Server 2016. At this point, the VMM server can 'see' the shares but can not calculate share size (reports 0GB) and therefore can't manage the share(s). Since then we've tested with multiple other 2016 and Windows 10 machines - all with the same result: added to the whitelist but can't browse the share, even from Windows Explorer. We are looking for confirmation that this is a known issue. If so, can you confirm if it's resolved by an upgrade to v5.0.2?

Nutanix - HyperV - iSCSI.

Hi, Can someone advise if possible to present iSCSI block services from DFS to Hyper-V host running on Nutanix Cluster. We have AOS 5 and we running Hyper-V 2012 R2 on our Nutanix Nodes. Why? This is to address problems with backup of VMs on SMB3. Possible alternative: Present iSCSI volumes from the underlying DFS to the Hyper-V nodes and migrate from SMB3 to iSCSI for VM. Then we should be able to do full VM back ups?? Would love to hear opinions / experience / feeback on the above idea. Thanks.

Self Service Restore portal hangs

When I load the SSR portal through the desktop shortcut, or by browsing to locahost:5000 within a second or two the browser chokes and becomes unresponsive. I thought it may be related to the background animation, does anyone experience this also? Is there a way to disable the animation in the SSR portal page? Mant thanks, Daniel

Managing log truncation (SQl/Exchange etc) when using CloudConnect backup

Hello, Could anyone offer ideas around how to manage the log truncation for applications like Exchange/SQL when moving to CloudConnect from a product that used to perform that automatically? This seems like a pretty important aspect which I can't seem to find any information on. Many thanks, Daniel

"Old generation AWS instance is configured for remote site AWS"

Hello, I am receiving the following alert: "Old generation AWS instance is configured for remote site AWS. Follow KB 3861 to change the instance type to m3.2xlarge and cloud CVM configuration for better RPO/RTO." The remote site was configured only about a week ago and it spun up an instance size of m2.2xlarge. I cannot find any reference to the KB article 3861, or anything about changing the instance size. Does anyone have any ideas? Many thanks, Daniel

RECLAIMABLE SPACE row shows "Processing"

Hello, I connected a CE Edition to our nutanix to test async data protection. A snaphot from the remote side always show "processing" in Async Dir -> Local Snapshots -> Row "RECLAIMABLE SPACE" also if the snapshot was done days before so "processing" is suspicous. Is this a known issue, limitation of ce, bug, or config problem. /Greetings René

Create Test Environment Alongside Production Environment

Hello Everyone! I am using AHV and would like to create a duplicate of my production environment alongside the actual production environment. The point is that we have some highly specialised network software that needs to be tested as though in the actual environment before we actually deploy it there. This software is frequently updated and occasionally an update creates havoc, requiring lots of downtime and restoration of significant portions of the network. So what i am looking for is to have a protected space in AHV that thinks and behaves identically to our production environment (but with no actual interaction with the real network or the internet ... just via AHV consoles.) Thank you in advance for any help you can offer!

SOLVED - Snapshot status for vstore failed during backup with EMC amavar backup

Every time we launched the backup jobs we were receiving this critical warning: Snapshot status for vstore XXX: Failed. VM "proxy avamar" on vstore xxx has files from multiple vstores yyy, zzz. Skipping snapshotting this VM. The solution is to change the transporte protocol on avamar backup from hotadd to nbdssl. I hope this helps some of you

Cloudera in Nutanix VMs

Hi all! Is anyone out there running Cloudera in a Nutanix environment? Not just Hadoop, but specifically the Enterprise Cloudera Hadoop implementation. We're in the process of migrating our Production Cloudera cluster to Nutanix VMs and having a host of issues related to disk latency. I'm aware of the Nutanix Hadoop reference documents, but our configuration doesn't quite fit because it started on physical devices, and the existing production configuration would be challenging to change at this point. We're not running YARN yet, still on MapReduce V1, for example, though we're in the process of moving that direction in our dev environment. We have a storage container devoted to our HDFS directories, with virtual disks carved out of it in VMWare, but we're seeing vdisk latencies *averaging* 300ms with frequent spikes to several seconds. Our I/O is very write heavy; Nutanix advised us to disable EC-X, so we did, but no help. We're running RF2 on that container, no deduplication,

2TB vmdk to AHV Migration

Hi, I have a standalone ESX 5.1 server with a VM with multiple 2TB (screenshot from WinScp attached below) vmdk volumes. VM is Windows 2008 R2. My Nutanix cluster is running 5.01, NCC 3.0.0.2, AHV 20160925.30 - Starter Edition I am planning to use a Windows 2012 R2 server with WinSCP to get the vmdk files onto the Nutanix cluster container (I have multiple containers) and then use the Image service (via Chrome browser) to upload/convert via UNC to the container. Here are my questions: [list=1] [*]I'm wondering if there are any limitations on the Image Server when using the Chrome Browser [*]Any potential issues with these vmdk sizes? [*]What is the syntax for the URL to access the Storage Container so I can upload the vmdk without using the UNC? -Figure this one out. In Image Service use nfs://clusterip/Containername/name ofvmdk-flat.vmdk [*]Since I need to upload multiple vmdk files that quite large, can/should I open multiple browsers to get simultaneous uploads happeni

HyperV/Nutanix (SMB), VM import from Hyper-V manager

Hi, I'm trying to import a VM using hyper-V manager but it is always saying "can't access folder, you might have not permission to access this folder" and tried to check all VMs and the same issue shows up. Any idea why this error is there? I'm thinking about modifying the permissions on VM folder, can we? knowing that i'm trying to access the VM folder from container share path [example: \container_name.........] We are running hyperV2012R2 on nutanix 4.7.1 Thank you, Pierre

SSH Public Key is removed from ESXi

Hi,we are running 20 Nutanix Nodes with AOS 5.0.1 and ESXi 6.0 as hypervisor. Normally we using passwordless login to the ESXi host using SSH Keys. So we copy our public key as usual to /etc/ssh/keys-%u/authorized_keys, but after a reboot of the ESXi Host our keys are removed.So I modified the sshd_config on the ESXi host to use multiple authorized_keys- AuthorizedKeysFile /etc/ssh/keys-%u/authorized_keys+ AuthorizedKeysFile /etc/ssh/keys-%u/authorized_keys /etc/ssh/keys-%u/authorized_keys2But even with this config, the authorized_keys2 is also deleted.Can anyone assist me to solve this issue in case of our internal security guidline to use passwordless login.Best regardsMarkus

Backup from AHV

Hi everyone, considering AHV hypervisor, which are the possible options to backup the virtual machines? As far as I know, the only certified backup software is commvault... but I was wondering if AHV/prism can do vm-level backup and which are the features (guest/application consistency, possibility to file level restore ecc....) and differences compared to Commvault. Thank you

Install NGT on VM template before Sysprep?

Is it ok to install Nutanix Guest Tools in a guest vm template before the template is Sysprepped? I need to deploy a bunch of Server 2008 r2 VMs that will need NGT. I'm aware that it's easy to automate NGT install AFTER vm deployment and I do that for most cases; however on Server 2008 r2 builds there's a techinical limitation that prevents this from working. So I'm wondering if there is anything in NGT that will break if the vm is Sysprepped afterward.
