Deploying new Linux hosts

With a few exceptions, you prepare the new hosts as you did during the initial installation process.

To deploy new or reinstalled physical or virtual Linux hosts, follow the procedure "Preparing the hosts" in the StorageGRID installation instructions for your Linux operating system.

This procedure includes steps to accomplish the following tasks:

Install Linux.
Configure the host network.
Configure host storage.
Install Docker.
Install the StorageGRID host service.
Attention: Stop after you complete the "Install StorageGRID host service" task in the installation instructions. Do not start the "Deploying grid nodes" task.

As you perform these steps, note the following important guidelines:

Be sure to use the same host interface names you used on the original host.
If you use shared storage to support your StorageGRID nodes, or you have moved some or all of the disk drives or SSDs from the failed to the replacement nodes, you must reestablish the same storage mappings that were present on the original host. For example, if you used WWIDs and aliases in /etc/multipath.conf as recommended in the installation instructions, be sure to use the same alias/WWID pairs in /etc/multipath.conf on the replacement host.
If the host for the StorageGRID node will use storage assigned from a NetApp All Flash FAS (AFF) system, you must confirm that the FlexVol does not have a tiering policy enabled.
Attention: Never assign storage for a StorageGRID node from a FlexVol with an active tiering policy. Node outages might occur if storage used by the StorageGRID node is tiered to a capacity tier.
