Hello, I understand that if the node fails, the ha function is activated and attempts to recover. If one node fails in a Data Resilience Status Critical state due to a lack of storage space, will the cluster collapse? What happens.

Morning all!I have a 5 node cluster (5.20/ESXi7.0U3).  its about 4-5 years old.  Just got approval to upgrade and ordered a new 5 node cluster.Question:  Is it best to expand current cluster and remove a node at a time, or set up net new and migrate?Looking for suggestions and experience.Thanks in advance!TJ

Can someone provide a brief explanation of Nutanix local key manager and how it handles the following in ‘???’:key access: access to the management console is restricted to authorized individuals abased on job function. changing / updating keys: encryption keys are updated from the management console, software encryption (rekey button) if necessary. revoking keys: ??? (when does revoking keys happen?) recovery keys: ??? (how do you recover if you have the key backup?) archiving keys: keys are archived (backed up) from the management console, managed keys where you download the key backup by setting up a recovery password to decrypt the backup file.  activity logs: ??? (is there activity logs for keys? If yes, where is this stored and how long is the retention before the activity is overwritten?)BTW: I have this link already Native Local Key Manager (nutanix.com) but is does not have any details of the Thanks in advance.

Hello,I would like to change the password expiration for a local user I have created in the prism element.I’ve tried to change it via the command:nutanix@cvm$ sudo chage -M <MAX-DAYS> admin I’ve managed to do that to the admin user, but when I change “admin” with my local user, It says that the user does not exist in etc/passwd. Is their any way of changing the password expiration for a local user that it is not “admin”.(The user is a cluster admin).

Greetings, Does the Nutanix Local Key Manager (LKM) satisfy the recommendations/requirements to safely implement the Data at Rest Encryption?The documentation at: https://portal.nutanix.com/page/documents/details?targetId=Nutanix-Security-Guide-v6_5:wc-security-data-encryption-aos-wc-c.html has the warning: "Caution: DO NOT HOST A KEY MANAGEMENT SERVER VM ON THE ENCRYPTED CLUSTER THAT IS USING IT!! Doing so could result in complete data loss if there is a problem with the VM while it is hosted in that cluster." I too share this concern, which led me to investigate External Key Managers, but I am wondering how does using the LKM alleviate this risk? Also, as stated in the Nutanix Bible as well as here: https://portal.nutanix.com/page/documents/solutions/details?targetId=TN-2026-Information-Security:TN-2026-Information-Security "Now that Nutanix supports its own native LKM, Nutanix also takes the KEK and wraps it with a 256-bit encryption key called the machine encryption key (MEK).

We have our Nutanix 5 node cluster installed with VMware vSphere 7.0U3. RF=2 so I should be bale to withstand a 1 node failure. I would like to test the HA capability of VMware/Nutanix by taking a node offline abruptly and ensure everything works as expected before placing production workloads on it.I was thinking of placing a test VM on a node and then pulling the power cables and ensuring that VM is powered up on a remaining host.Does anyone have any better or preferred way to test HA?

Hi!We are running about 100 vm’s in our cluster - so find out a specific information manually for each vm is pretty hard.I want to get the information which vm’s are stored in a specific storage container with acli on cvm.I know that i could perform acli vm.get <vm-name>  and look for the source_nfs_path of the vmdisks but it is way too much effort for 100 vm’s. Another way would be establishing a connection via SSH to /storage-container/.acropolis/vmdisk of of the cvm but i only see the vmdisk-uuids there, not the vm names i need.Is there any possibility, maybe with a for loop on each vm and a grep filter?
