We've just gotten started with Nutanix, and I have a question about snapshots. Do I need to create a Protection Domain before I can create a snapshot? I'm not looking to take snapshots of a bunch of machines or have scheduled snapshots. I just want to make one snapshot of a single Windows server before I upgrade some software on it. We are running AHV as our hypervisor. Thank you
Is anyone using Veeam to backup their virtual environment on a Nutanix cluster? If so, how have you configured your backup proxy (how many, virtual or physical, 1 arm or 2 arm configuration, etc)? What are you using for a backup target? What kind of throughputs or processing rates are you seeing? I am running some test jobs, and a few of the jobs I have run identify the soure (Nutanix) as the bottleneck in the job. My backup proxy is a VM with a 2 arm configuration (1 vNIC in the production storage VLAN and 1 vNIC in the backup storage VLAN) running in Network Mode. I'm wondering if there are other modifications I can make to alleviate the source (Nutanix) from being the bottleneck in the jobs.
The alert text “Connectivity to remote site is not normal” may show up for a number of different reasons, so it may not be immediately clear what to do about it. If you have recently added a remote site configuration in Prism it could be some problem of configuration, but if you had Async DR replication working for several days before the error popped up the issue is more likely to be related to network issues or the status of the remote site. Since the cause might only be temporary, the first thing to do is to re-run the check. To see the full detail I recommend running this one from the CLI: nutanix@cvm$ ncc health_checks data_protection_checks remote_site_checks remote_site_connectivity_check If you see a PASS result now and no corrective action was taken, the issue was temporary. If that’s the case you may want to check the alert timestamp and look into whether the network or remote site was undergoing maintenance or upgrade, or exhibiting some issue at the time of the alert. Since
Hello, New to Nutanix. I'm trying to add VM's to a protection domain via the webconsole, but some VM's I want to add aren't showing up. What's interesting is on the VM sumary page in Prism shows I have 66 VM's, but vCenter shows 81. Is there an easy explanation for this? I am on Esx 5.5 and AOS 4.5.2 Thanks!
Hi everyone, I´m trying to export the VMs from AHV in vmdk and qcow2 formats directly from a CVM. Sometimes I get the errors bellow: qemu-img: NFS Error: NFS: Write failed with NFS3ERR_JUKEBOX(-11) qemu-img: error while writing sector 44426880: Resource temporarily unavailable In other situations Putty just close in the middle of the copy. After several retries, I finally made backup of two big VMs (around 50 gb). The commands that I am using are: qemu-img convert -O vmdk nfs://127.0.0.1/TKWORKSTATION/.acropolis/vmdisk/d9759595-6dee-4138-bcc0-bad7bf8e1075 nfs://127.0.0.1/Backup_VM/TAIPEI.vmdk qemu-img convert -c nfs://127.0.0.1/TKWORKSTATION/.acropolis/vmdisk/d9759595-6dee-4138-bcc0-bad7bf8e1075 -O qcow2 nfs://127.0.0.1/Backup_VM/TAIPEI.qcow2 Nutanix Community lastest version. Thanks in advance!
How does one navigate in the ocean of solutions that are available on the market? What is supported? What is compatible with which hypervisor? Allow us to help! Here is part two of supported backup solutions together with an overview of each. RUBRIK Top significant functionalities: Instant Recovery: deliver near-zero RTOs for Hyper-V or vSphere VMs by mounting directly onto Rubrik. No rehydration required. Global Real-Time Search: search for VMs and files with suggested search results. API-first Architecture: automate custom lifecycle management workflows that play well with third-party services (i.e. Chef, Puppet, ServiceNow, VMware vRealize Automation). Customized Analytics: deliver platform analytics across the hybrid cloud on data management, compliance, and capacity utilization with Rubrik Envision. Create and share data visualizations. Policy-Based Management: use an SLA policy engine to create and automate policies. Protects NoSQL Databases on Nutanix Enterprise Cl
Hello, Is there a way (other than REST or scripting/crontab) to put any new VM created inside a container to a "default" protection domain? The rationale is to create a "standard" policy for all VMs of a cluster like "this cluster is replicated every 2h, by default", then if exceptions need to be handled, they can be treated on a case by case basis. I have a customer that is PoCing Nutanix, with the goal to move from a NetApp/NFS/IBM Blades solution to Nutanix if everything goes well. Problem is, they use SnapMirror to replicate their datastore (1 by cluster) every 1h. They do want to be able to replicate just a VM, but they don't want to have to add each new VM individually to a protection domain. Sylvain.
Hi, I’m new on the Data protection feature. I’ve done the a test VM migration to another nutanix cluster. The thing is after the migration, the VM on the source will be destroyed. I’m planning to use the Data protection to migrate the VM from the source cluster to the target cluster. I would need to failback the VM to the source VM. Am I able to restore the VM on the source site?
Does anyone know if/how I can get a count of all vDisks in my cluster, including vDisks associated with snapshots? We want to increase our data retention and it appears the limitation on snapshots is the number of vDisks so I need to figure out how many we have with our current number of VMs and snapshots. Running AOS 5.6, NCC 3.5.2, Hyper-V 2012r2. Any help appreciated, please let me know if there's more info I can provide. Thanks! David
I have issue about Rubrik backup. I have monitored that some vms could not backup some days with alerts are same. However, some days work fine.[img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/10508755-dbb2-4d48-a12a-4bb18e04410c.jpg[/img][img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/a6fad98e-7e72-44b8-8b57-38e325ea3cdf.jpg[/img]
Hi, Our customer would like to utilize the snapshot feature on Nutanix AHV as backup solution. They would like to know if they could create Application Consistent snapshot. I did some research. 1. In the Web Console Guide which mentioned about Application-Consistent Snapshots "This option is available for ESXi only; it is not supported for Hyper-V or AHV. However, athird-party product could be used to invoke VSS when the hypervisor is Hyper-V or AHV." 2. QEMU should have guest agent and which the VirtIO Driver should have included. So, my question is. Can Nutanix AHV support Application Consistent snapshot. Thabnks
I need someone to light my bulb regarding data protection scenario I have in my mind. Currently we're migrating from NetApp/UCS ESX to Nutanix ESX and we uses Commvault as data protection. In addition to Commvault, we uses volume snapshot in NetApp for DR and fast recovery. This does not replicate to remote site however. In Nutanix, I have configured container for Prod and Dev/QA datastores. Prod datastore protected by Commvault intellisnap and keep two day worth of snapshots. DEV/QA datastore does not protected by Commvault due to licensing issue, we would like to use Nutanix data protection to have similar data protection like Prod datastore (2 day snapshots) . My question is, writing script to adding VMs automatically to data protection domain is the only way to go? Or any other suggestion?
Ok Everyone, I am fairly new to the Nutanix system as our company recently decided to upgrade all server hardware to a Hyper-Converged system. Because of this, my knowledge of the backupsnapshot systems used by Nutanix is very limited, so please bear with me. So heres the issue; yesterday afternoon one of UPS burned itself up and caused a sudden power outage in our core datacenter. This location houses our primary Nutanix 4 node cluster. This is also the location where all employee profiles are stored using the Nutanix File Server system. After power was restored and th Nutanix system powered back up (took roughly 30mins) all services seemed to be restored. The next morning however, we started recieving calls about users not being able to login to the system. They are getting errors about network profiles not being available. Quicking checking the HomeShare location, we quickly determined the users home profile folder is suffering some issues. Properties shows 0bytes and all tabs a
Hi Cloud builderWhile I was reading the NTNX Bible they said that the VM snapshot being taked by freezing the VM, unlikely with ESXi where the VM is stunned » Delta created for I/Os and then VMDK is consolidatedMy question while on NTNX Platform how/when the I/O takes place while VM is being snapshot’ed while its freeze.
Using near sync replication in AOS 5.5 means that normal snapshots on VMs cannot be initiated by external backup tools like comtrade, rubrik This is a bit of a showstopper. If we need an RPO of 15 minutes on AHV, we have to use nearsync - but then we can't backup VMs off the cluster When will Nutanix resolve this rather major downside?
Thoughts I'd post this rather than bugging our SE over and over ;) Trying to get a disaster recovery plan in place to protect against a major disaster such as server room fire... We have a couple of clusters geographically separated which I have set up as remote-sites. Site A and B lets call them. I've set up a PD w/ consistency group with the VMs to protect and periodically snapshot from site A to B. Now in the case of a fire/destroyed cluster at site A... obviously step one is rebuilding a cluster at that site with the appropriate configs, but then... With a brand new cluster in place, what is the standard process to retreive the snapshots from site B back to the new site A ? So far, I've activated the backup on site B (as if it was an unplanned outage and left it off). and recreated the remote-site link on the newly built out site A. I am thinking I now create a new PD to shuffle the VMs/consistency group back to Site A and then activate there and I am done ? I know this
If you need to clear up space on your Nutanix cluster you may be considering removing local snapshots, but what if the reclaimable space is displayed as “Processing”? What can we do about it, and how can we know if a snapshot is worth removing? The reclaimable space is subject to change and has to be totaled up before it can be known. This work is done during the same periodic filesystem scans which drive disk clean-up, post-process deduplication and compression, and information lifecycle management. Generally speaking we just need to wait for the next periodic scan to finish and then we should have the reclaimable space figure shown in Prism. If you need to estimate reclaimable space in the meantime, I can offer a few hints to help narrow that estimate. It helps to have a little understanding of how snapshots work, and how the reclaimable space number is identified. Think of it this way. Each current filesystem block has one or more owners, and any block cannot be deleted until no mor
