Create filesystems (SLES 15)

For SLES 15, 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.

   # multipath -ll
   

   The result of this command shows device nvme0n6.

   eui.000082dd5c05d39300a0980000a52225 [nvme]:nvme0n6 NVMe,NetApp E-Series,08520000
   size=4194304 features='n/a' hwhandler='ANA' wp=rw
   |-+- policy='n/a' prio=50 status=optimized
   | `- 0:0:1 nvme0c0n1 0:0 n/a optimized     live
   |-+- policy='n/a' prio=50 status=optimized
   | `- 0:1:1 nvme0c1n1 0:0 n/a optimized     live
   |-+- policy='n/a' prio=10 status=non-optimized
   | `- 0:2:1 nvme0c2n1 0:0 n/a non-optimized live
   `-+- policy='n/a' prio=10 status=non-optimized
     `- 0:3:1 nvme0c3n1 0:0 n/a non-optimized 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 (22-Oct-2019)

   Superblock backups stored on blocks:

   Writing inode tables: done
   Creating journal (32768 blocks): done
   Writing superblocks and filesystem accounting information: done
   
   
   

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
