Quorum must be up, at least 2 corfu servers required for quorumĤ. # API query and configure (Postman, Insomnia)Ĭonnect-VIServer -Server # Connect to vCenterģ. # Retrieve all available commands to query and configure Once I swapped over to using the datastore, I was able to successfully install the NSX-T components.VMware NSX-T Data Center Troubleshooting Enter privilege mode and command mode st en # NSX manager privilege modeĮsxcli # ESXi host to enter esxcli command mode In my case, the VMware ESXi Error No Space Left On Device Installing NSX-T Components was indeed related to the swap file location being the “preferred swap file location” instead of utilizing a datastore. If you are perhaps having issues with pruned down, nested ESXi host instances in a lab environment and you are having disk space errors, the swap file could very well be the culprit. Preferred swap file location – Allow the use of the preferred swap file location configured for the host. Host Swap Cache – Allow the use of part of the host swap cache. Please note that a vSAN datastore or a VVol datastore cannot be specified for system swap files. If none of the options are feasible then system swap is not activated.ĭatastore – Uses the datastore specified.
The system selects the best possible enabled option. This decision can be aided by selecting a certain set of options. The Preferred swap file location is where ESXi determines automatically where the system swap is to be stored.
Of course reading from background storage is much slower than reading from memory, so you must be careful when and where swapping is used from background storage. Reclaimed memory is written to background storage after it has been taken out of memory. The amount of space required for the system swap is 1GB. When system swap is enabled you have a tradeoff between the impact of reclaiming the memory from another process and the ability to assign the memory to a virtual machine that can use it. System swap allows the system to reclaim memory from memory consumers that are not virtual machines. System swap is a memory reclamation process that is used to take advantage of any unused memory that may be available across the entire system. What is the System Swap anyway? Per the KB:
