To Dr-site Replicaton be suspended.

Hello  Data replication, which was well done until yesterday, has stopped and is not progressing. Only one of the five scheduled schedules will be suspended. Note that the three entities that correspond to the schedule are excluded from the schedule for a while. After increasing the cpu and memory, I included it again. Is there any part or command I need to check? This is a dark site, so remote assistance is not available. Help me.

Metro Container Storage Missmacht

Hey guys,I made a quite new discovery that is totally new to me and I try to understand where this is comming from, maybe someone can help :)Scenario: There are 2 ESX clusters, connected via Metro. The DataStore on the source site is ~2TB, the datastore on the destination is about 1TB and I have no clue why :)Both DataStores only use compression, there are no other snapshots on the source side and this is for a couple of days now, so no curator run should be involved. Ideas anyone? Cheers, Flo

My cloud connect question was closed without explanation

I opened a thread a month ago about Cloud Connect S3 consumption and when checking on it today I found that it was closed to comments.https://next.nutanix.com/nutanix-disaster-recovery-29/aws-cloud-connect-s3-consumption-issue-41499?postid=63137#post63137There was no explanation for this action in the thread or via PM to me. Can someone let me know why this was done?

Creating SQL Server HA cluster with DR

Hi,I have two Nutanix clusters on different sites (one on each site) a few miles apart with 10GB low latency networking in place.I have setup a two node failover SQL Server cluster for HA on a single site, but I would like to add DR to the solution.I know Availability groups (and other options) are a good solution for this, but we can’t implement those at present and so I am looking for the ‘correct’ way to replicate the two node HA that we have (With it’s shared storage) across to the second site so that our front-end application will continue to function in the event of a site failure.Any tips or pointers would be very much appreciated!Thanks

Two-Nodes Cluster Replicate to One-Node Cluster

Hi,We have two locations and want to install Two-nodes-Cluster in the production location and One-node-cluster in the Disaster Location and to replicate these clusters each other. My question is:Can we connect two-nodes directly with 10 Gbit DAC SFP+ cables each others? So, Is physical switch necessary to install two-nodes-cluster? We want to use Direct Connection (via DAC Cables) for RF2 data replication between two-nodes and 2 x 1/10 Gbit Base-T port will be using for VMs connection and replication VMs to one-node-cluster in the DR site. Is this scenario possible? What about fail-back scenario? (back from DR to Production)Notes:We have 3 x NX1175S G8 Nodes We want to use AHV or ESXiThanks.

Nutanix Data Protection about Three Sites in Two Places

Hello guys,We are considering upgrading the existing Nutanix cluster environment to meet high reliability protection for critical applications.Currently we have a site A as the production cluster and site B as the disaster recovery cluster. The sites on both sides use Leap to provide a data protection strategy with an RPO 15 Mins.All sites' virtualization systems are using AHV.Now we plan to build a new site C, and do real-time synchronous data transmission with site A.Site A and Site C will be deployed in the same building.At the same time, it is hoped to ensure that the failure of either site A or site C will not cause data loss or service interruption.We hope to use Nutanix's data synchronization solution.However, we found that once the VM uses Leap to configure the real-time synchronization policy, the original Leap asynchronous transmission policy cannot be applied.It appears that only one Leap protection policy can be applied to the same VM.Therefore, based on the above situation

AWS Cloud Connect S3 consumption issue

We bought several Nutanix clusters in 2019 and on two of them, we deployed a cloud connect appliance in AWS via Prism element so that we could backup our VMs to the cloud. We setup retention to 7 snaps locally and 62 on the remote (AWS) side. The question I have for everyone that uses Cloud Connect for backups is, does the S3 bucket that gets created by Cloud Connect ever stop growing in size. On our HQ Nutanix cluster, that Cloud Connect S3 bucket is currently sitting at 164TB and 177 million objects. This is a small 3 node cluster with only 10 VMs being backed up to the Cloud Connect appliance. Current allocated space for those VMs is 3TB. Actual consumed by them as reported by Prism is about half of that. Looking at the S3 bucket created by cloud connect, I see that a lifecycle rule was created to move objects to infrequent access after 30 days. I see nothing to expire old objects and there are objects in the bucket dating all the way back to 2019. So at first glance, it doesn’t loo

PD CVM requirement

I  have a question about PD snapshot frequency.Referring to below link, a node with 32-64 TB HDD tier support NearSync and hourly snapshot with specify requirement (e.g. 14vCPU for CVM).Node Configurations for Snapshot or Recovery Point FrequencyIf I have a 64TB HDD nodes with 2 x 12 cores CPU, the CVM will configured with 12vCPU after foundation. Does it means that node not supporting hourly snapshot and NearSync?

VEEAM Protected VM's

I have a question about the “protected VM’s” in VEEAM for Nutanix. In the beginning, we had a problem with a Exchange Server logs. when the backup was complete with VEEAM for Nutanix the Logs from exchange are not truncated.The workaround was to create a new job directly on the VEEAM Server and configure the VSS to truncate the logs. It’s working fine! But the problem now is : the exchange server is in the Group of protected VM. When we try to delete from the protected VM group , the VM comes automatically in the group after 15min. Anyone have an Idea? Because the problem is now we have 2 different backups of the same VM.

LEAP implementation Question

We are in the process of setting LEAP in our environment. We have a Nutanix three node cluster that contains our Production VM’s. We have another Nutanix three node cluster that is going to be used for DR. Right now this DR cluster doesn’t have any VM’s on it besides the Controller VM’s. Currently the DR cluster is located in the same data center as the Production cluster. Our plan is to move the DR to a different data center. What I’d like to be able to do is setup LEAP and have everything replicate prior to moving the DR cluster to the new datacenter. This would allow the process to replicate over our LAN instead of the WAN. Is it possible to set up LEAP to do replication locally like this and then once we move the DR cluster to the new data center, reconfigure LEAP so that it points to the DR cluster. The DR cluster will also be reassigned new IP addresses once it moves to the new data center.

Synchronous Replication Requirements

Hello everyone.I am planning synchronous replication between two sites with AHV, and the prerequisites are not clear in the documentation. I have 960GB SSD disks on the hosts. Apparently the minimum required is 1.2TB but it's not explicit in the documentation. Does anyone know where I can validate this information? Thanks! :)

Recover files from VM

Hi,I have a VM that the network is not working, so we will make another VM.The problem is that we need one folder storaged in the disk. Can we download this folder?I know that in VMWare you can go to the disk and copy the folder in the Hypervisor. Has Nutnix this function?Best regards,Eneko.

If space is not recovered after 36 hours feat snapshot

Hello, warriors of the digital ageCould you help a beginner in trouble? https://next.nutanix.com/discussion-forum-14/snap-shot-delete-but-have-a-large-capacity-41093 https://portal.nutanix.com/page/documents/kbs/details?targetId=kA03200000098CQCAY  A few days ago, I asked about the capacity increase due to snapshots, and I was told that curation would return to normal in about 36 hoursHowever, when I checked, I realized that the capacity was not reducedIf the capacity is the same, open the case and get support from Nutanix's SREThe customer's contract has expired, so we can't get supportWhat should we do to reduce capacity? Where should I look?I would appreciate it if you could answer this question​​​​​​​​​​​​​​​​​​​​​

Automated VM export

I want to be able to export a VM in OVA format from powershell.  I suppose any script or command line function would work, but I want to automate the process.  We have a large fileserver VM with millions of very small files.  Backing up that many files is taking longer than we would like, so we ideally want to just export the VM on a daily basis and have the backup done that way.  It should be faster to do that than to have a backup process handle millions of tiny files, the overhead is just too much.I already have a script that will clone the VM and delete the VM, I just need the middle part to export the VM out of Nutanix to have that backup copy.  If I can’t get the full VM as I would prefer, I could tolerate having copies of the VM disks copied out as an automated process, to recreate the VM at a later date.  This backup copy will only be for extreme emergencies, we already have snapshots of the VM and replicas at our remote site, but for auditing purposes we need a copy of the dat

Snapshot/Recovery point/Revert-Restore from user-view

Hello all experts,I have some question about create/revert snapshot/recovery point of VM in AHV cluster:Can user (have permission to access cluster portal to clone VM, create recovery point) access and create recovery point by themselves? Can they revert/restore the snapshot/recovery point by them-self (the same as Hyper-V)? What if they request to do by themselves, what I need to do? Now I have admin permission but cannot revert, just can clone VM from recovery point.Thank you so much

NearSync not working for a particular VM

Hello everyone,I started a new project in which we need to be prepared for a Disaster Recovery between 2 Nutanix clusters in different regions. I did the Data Protection from Prism Central just fine in the beginning, already have 8 VM with NearSync enabled with RPO of 15min. However, this new VM has been giving me trouble lately, giving me a RPO up to 3 hours because of the following issues: Warning : Snapshot Replication to Remote Site is Lagging.Warning : Snapshot queued for replications to remote siteWarning : Entity is being transitioned to a lower frequency snapshot schedule. To be fair this new VM is kinda big, with 10 cores, 50GB RAM, and 1.22 TB storage used. It’s for a high transactional MSSQL Server database.I am basically stuck deciding if this is a networking problem, or a workload capacity from Nutanix problem.We are supposedly using 200MBps LAN-to-LAN networking, with a 20ms latency. Should this be enough?On the other hand, I am looking in Nutanix’s Analysis section that
