One thing I&rsquo;ve noticed, however, is that it takes forever to create an ext3 filesystem on a new volume. For example, the below command took over 30 minutes to create the filesystem on a 300 GB volume:</p> <blockquote> <h1 id="mke2fs--j--m0-devsdf1">mke2fs -j -m0 /dev/sdf1<a class="heading-anchor" href="#mke2fs--j--m0-devsdf1" aria-label="Link to this section"> <svg viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2.2" stroke-linecap="round" stroke-linejoin="round" aria-hidden="true" focusable="false"> <path d="M10 13a5 5 0 0 0 7.54.54l3-3a5 5 0 0 0-7.07-7.07l-1.72 1.71"/> <path d="M14 11a5 5 0 0 0-7.54-.54l-3 3a5 5 0 0 0 7.07 7.07l1.71-1.71"/> </svg> </a> </h1> <p>mke2fs 1.40.4 (31-Dec-2007) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) 39321600 inodes, 78642183 blocks 0 blocks (0.00%) reserved for the super user First data block=0 Maximum filesystem blocks=4294967296 2400 block groups 32768 blocks per group, 32768 fragments per group 16384 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624, 11239424, 20480000, 23887872, 71663616</p>
