E-Series storage systems

Create filesystems in E-Series - Linux (NVMe over RoCE)

For RHEL 9, RHEL 10, SLES 15, and SLES 16, you create a filesystem on the native nvme device and mount the filesystem.

Before you begin

Make sure you have completed the accessing NVMe volumes for an E-Series target from the host task to ensure the NVMe devices are properly configured and accessible.

Steps

  1. Create a file system on the partition for the desired nvme device using the location /dev/disk/by-id/nvme-eui.[id#].

    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)
Creating filesystem with 2620928 4k blocks and 655360 inodes
Filesystem UUID: 97f987e9-47b8-47f7-b434-bf3ebbe826d0
Superblock backups stored on blocks:
        32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632

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

  2. Create a folder to mount the new device.

    # mkdir /mnt/ext4

  3. Mount the device.

    # mount /dev/disk/by-id/nvme-eui.000082dd5c05d39300a0980000a52225 /mnt/ext4
What's next?

After you create the filesystems, record your NVMr over RoCE configuration information.
