Create filesystems

For SLES 15 SP1, you create a filesystem on the native nvme device and mount the filesystem.
  1. Run the multipath -ll command to get a list of /dev/nvme devices.
    The result of this command shows device nvme0n1:
    eui.000007e15e903fac00a0980000d663f2 [nvme]:nvme0n1 NVMe,Lenovo DE-Series,98620002
    size=207618048 features='n/a' hwhandler='ANA' wp=rw
    |-+- policy='n/a' prio=n/a status=n/a\
    | `- 0:10:1    nvme0c10n1    0:0 n/a   n/a   live
    `-+- policy='n/a' prio=n/a status=n/a\
      `- 0:32778:1 nvme0c32778n1 0:0 n/a   n/a   live
    
  2. Create a file system on the partition for each /dev/nvme0n# device. The method for creating a file system varies depending on the file system chosen. This example shows creating an ext4 file system.
    # mkfs.ext4 /dev/disk/by-id/nvme-eui.000082dd5c05d39300a0980000a52225 mke2fs 1.42.11

  3. Create a folder to mount the new device.
    # mkdir /mnt/ext4
  4. Mount the device.
    # mount /dev/disk/by-id/nvme-eui.000082dd5c05d39300a0980000a52225 /mnt/ext4
