• For all other types of federated cell members servers - you may map the mount points to any disk.

Creating Mount Points

Use LVM (Logical Volume Manager) to create the mount points. You may use the following commands as an example of how to configure a single mount point (/data2 in this case):

pvcreate -ff /dev/nvme0n1
vgcreate vg_data2 /dev/nvme0n1
lvcreate -l 100%FREE -n lv_data vg_data2
mkfs.xfs -f /dev/vg_data2/lv_data
echo "/dev/vg_data2/lv_data    /data2                   xfs     defaults        0 0" >> /etc/fstab
mkdir -p /data2

Inspecting final configuration

Execute the following command and verify mount points (this example is for 6 disks per cell member and does not include other mount points that should exist):

lsblk

Expected output:

Cell Member Federation

In order to federate and configure the cell member, run the following script in the cell manager once per cell member.
For instance, to federate two cell members, the script should be run twice (in the cell manager) - first time with the IP address of the first cell member, and second time with the IP address of the second cell member.
