Mount partition

Create the mount point

# mkdir /mnt/images

Mount the partition as a loop with the correct offset 512 * 2048 = 1 048 576

# mount -o loop,offset=1048576 IMAGES_00000 /mnt/images

Check the mount

# mount | grep /mnt/images
/volume2/@iSCSI/LUN/BLUN/e5f5aa43-d1a3-47cf-a69a-97b25505acde/IMAGES_00000 on /mnt/images type ext4 (rw,relatime,data=ordered)

Read only

If you need the partition mounted as read only, add the ro option

# mount -o ro,loop,offset=1048576 IMAGES_00000 /mnt/images

Check the mount

# mount | grep /mnt/images
/volume2/@iSCSI/LUN/BLUN/e5f5aa43-d1a3-47cf-a69a-97b25505acde/IMAGES_00000 on /mnt/images type ext4 (ro,relatime,data=ordered)

Unmount partition

# umount /mnt/images/
