2. Ensure that all nodes have the same version of Proxmox VE:
pveversion
Step 2: Set Up the Proxmox Cluster
Create a new cluster on the first node:
pvecm create my-cluster
Add the other nodes to the cluster:
pvecm add <IP_of_first_node>
Verify the cluster status:
pvecm status
Step 3: Install Ceph on Proxmox Nodes
Install Ceph packages on all nodes:
install ceph ceph-mgr -y
Step 4: Create the Ceph Cluster
Initialize the Ceph cluster on the first node:
pveceph init --network <cluster_network>
Create the manager daemon on the first node:
pveceph createmgr
Step 5: Add OSDs (Object Storage Daemons)
Prepare disks on each node for Ceph OSDs:
pveceph createosd /dev/sdX
Repeat the process for each node and disk.
Step 6: Create Ceph Pools
Create a Ceph pool for VM storage:
pveceph pool create mypool 128
Step 7: Configure Proxmox to Use Ceph Storage
Add the Ceph storage to Proxmox:
Navigate to Datacenter > Storage > Add > RBD.
Enter the required details like ID, Pool, and Monitor hosts.
Save the configuration.
Step 8: Enable HA (High Availability)
Configure HA on Proxmox:
Navigate to Datacenter > HA.
Add resources (VMs or containers) to the HA manager.
Configure the HA policy and set desired node priorities.
Step 9: Testing High Availability
Simulate node failure: Power off one of the nodes and observe how the VMs or containers are automatically migrated to other nodes.
Step 10: Monitoring and Maintenance
Use the Proxmox and Ceph dashboards to monitor the health of your cluster.
Regularly update all nodes to ensure stability and security.
Optional: Additional Ceph Configuration
Add Ceph Monitors for redundancy:bashKodu kopyalapveceph createmon
Add more Ceph MDS (Metadata Servers) if using CephFS:bashKodu kopyalapveceph createmds
Tune Ceph settings for performance and reliability based on your specific needs.
By following these steps, you will have a robust Proxmox VE and Ceph high availability setup, ensuring that your VMs and containers remain highly available even in the event of hardware failures.

Configuring OSPF Redistribution
To redistribute routes from other protocols (e.g., BGP) into OSPF:
Cluster Setup: Ensure that your Proxmox hosts are part of the same cluster. A Proxmox cluster consists of multiple Proxmox VE servers (nodes) combined to offer high availability and load balancing to virtual machines. Nodes in a cluster share resources such as storage and can migrate VMs between each other.
Shared Storage: Live migration requires shared storage accessible by both the source and target hosts. This shared storage can be implemented using technologies like NFS, iSCSI, or Ceph. Shared storage allows the VM’s disk images and configuration files to be accessed by any node in the cluster.
Migration Prerequisites: Before initiating a live migration, ensure that the target host has enough resources (CPU, memory, storage) to accommodate the migrating VM. Proxmox will check these prerequisites before allowing the migration to proceed.
Initiating Migration: In the Proxmox web interface (or using the Proxmox command-line interface), select the VM you want to migrate and choose the “Migrate” option. Proxmox will guide you through the migration process.
Migration Process:
Pre-Copy Phase: Proxmox starts by copying the memory pages of the VM from the source host to the target host. This is done iteratively, with the majority of memory pages copied in the initial phase.
Stopping Point: At a certain point during the migration, Proxmox determines a stopping point. This is the point at which the VM will be paused briefly to perform a final synchronization of memory pages and state information.
Pause and Synchronization: The VM is paused on the source host, and any remaining memory pages and state information are transferred to the target host. This pause is usually very brief, minimizing downtime.
Completion: Once the final synchronization is complete, the VM is resumed on the target host. From the perspective of the VM and its users, the migration is seamless, and the VM continues to run without interruption on the target host.
Post-Migration: After the migration is complete, the VM is running on the target host. You can verify this in the Proxmox web interface or using the command-line tools. The source host frees up resources previously used by the migrated VM.
High Availability (HA): In a Proxmox cluster with HA enabled, if a host fails, VMs running on that host can be automatically migrated to other hosts in the cluster, ensuring minimal downtime.
Overall, Proxmox VM live migration is a powerful feature that enables you to move virtual machines between hosts in a Proxmox cluster with minimal downtime, providing flexibility and high availability for your virtualized environment.
Nodes: A Proxmox cluster consists of multiple nodes, which are physical servers running Proxmox VE.
Networking: Nodes in a Proxmox cluster should be connected to a common network. A private network for internal communication and a public network for client access are typically configured.
Shared Storage: Shared storage is crucial for a Proxmox cluster to enable features like live migration and high availability. This can be achieved through technologies like NFS, iSCSI, or Ceph.
High Availability (HA):
Proxmox VE includes a feature called HA, which ensures that critical VMs are automatically restarted on another node in the event of a node failure.
HA relies on fencing mechanisms to isolate a failed node from the cluster and prevent split-brain scenarios. This can be achieved through power fencing (e.g., IPMI, iLO, iDRAC) or network fencing (e.g., switch port blocking).
When a node fails, the HA manager on the remaining nodes detects the failure and initiates the restart of the affected VMs on healthy nodes.
Corosync and Pacemaker:
Proxmox VE uses Corosync as the messaging layer and Pacemaker as the cluster resource manager. These components ensure that cluster nodes can communicate effectively and coordinate resource management.
Corosync provides a reliable communication channel between nodes, while Pacemaker manages the resources (VMs, containers, services) in the cluster and ensures they are highly available.
Resource Management:
Proxmox clusters allow for dynamic resource allocation, allowing VMs and containers to use resources based on demand.
Memory and CPU resources can be allocated and adjusted for each VM or container, and live migration allows these resources to be moved between nodes without downtime.
Backup and Restore:
Proxmox includes backup and restore functionality, allowing administrators to create scheduled backups of VMs and containers.
Backups can be stored locally or on remote storage, providing flexibility in backup storage options.
Monitoring and Logging:
Proxmox provides monitoring and logging capabilities to help administrators track the performance and health of the cluster.
The web interface includes dashboards and graphs for monitoring resource usage, as well as logs for tracking cluster events.
Updates and Maintenance:
Proxmox clusters can be updated and maintained using the web interface or command-line tools. Updates can be applied to individual nodes or the entire cluster.
Configuring VMware ESXi for Active Directory (AD) authentication involves joining the ESXi host to the Active Directory domain and configuring user permissions accordingly. Here are the steps:
1. Access the ESXi Host:
Connect to the ESXi host using the vSphere Client or vSphere Web Client.
2. Configure DNS Settings:
Ensure that the DNS settings on the ESXi host are correctly configured, and it can resolve the Active Directory domain controller’s name. You can set the DNS configuration in the ESXi host under “Networking” > “TCP/IP Configuration.”
3. Join ESXi Host to Active Directory:
In the vSphere Client, navigate to the “Host” in the inventory and select the “Configure” tab.
Under the “System” section, select “Authentication Services.”
Click “Join Domain” or “Properties” depending on your ESXi version.
Enter the domain information, including the domain name, username, and password with the necessary permissions to join the domain.
Click “Join Domain” or “OK.”
Example:
Domain: example.com
Username: domain_admin
Password: ********
4. Verify Domain Join:
After joining the domain, you should see a success message. If not, check the credentials and network connectivity.
5. Configure Permission:
Go to the “Permissions” tab in the “Host” section.
Add the AD user account to the appropriate role (e.g., Administrator or a custom role).
Log out of the vSphere Client and log in using an Active Directory account. Use the format “DOMAIN\username” or “username@domain.com” depending on your environment.
Example:
Server: esxi.example.com
Username: example\domain_user
Password: ********
7. Troubleshooting:
If authentication fails, check the ESXi logs for any error messages related to authentication or domain joining.
Ensure that time synchronization is correct between the ESXi host and the domain controller.
Verify that the Active Directory user account has the necessary permissions.
Note: Always refer to the official VMware documentation for your specific ESXi version for the most accurate and up-to-date information. The steps might slightly differ based on the ESXi version you are using.
