However, if you are using Debian or Ubuntu Linux, you need to recompile the kernel. Step 3 Formating the system_new.img with EXT4 mkfs.ext4 system_new.img It will be a question where you will select yes (Y) We override the file system check (If you don`t do this, the image will not work) tune2fs -c0 -i0 system_new.img Step 4 We mount the directories that we previous created.
This can take a bit of time, but it should give you an update on what’s being written. mount -o loop system_new.img system_new/ mkfs.xfs -K /dev/sdx EXT4. mkfs.ext4 /dev/sdb1 It’ll now go off and start writing the filesystem.
when you do “mkfs -t ext4”, the search is on a standard directories list to find out the file filesystem builder(i.e: mkfs.ext4). The mkfs command formats with NODISCARD (also known as TRIM) by default. sudo mkfs.ext4 -L hdd_misha /dev/sdb1 BTW, normal users usually don't have the necessary permissions to use mkfs to format a partition (although they can format a disk-image file that they own - e.g.
XFS. Make sure you pass in the partition and not the entire disk.In Linux, disks have names like sda, sdb, hda, etc.The partitions on these disks have a number appended to the end. Linux Creating a Partition Size Larger Than 2TB last updated May 6, 2017 in Categories CentOS, Debian ... Redhat Enterprise Linux / CentOS comes with GPT kernel support. for use with FUSE or in a VM with, say, VirtualBox). To run mkfs without trim, use the -K option on XFS and -E nodiscard on ext4. – cas Aug 1 '12 at 10:14 but mkfs is something you usually only have to do once per filesystem - there are probably better things to optimise. In this example, the shared partition /dev/sdb1 is used to store the LVM physical volume from which the LVM logical volume will be created. or use XFS if filesystem creation time really bothers you - mkfs.xfs is a lot faster than mkfs.ext4 (because it doesn't do - or need to do - as much). So we would want to use something like sda1 and not sda.. sudo mkfs.ext4 -L datapartition /dev/sda1; If you want to change the partition label at a later date, you can use the e2label command: mkfs.ext4 -E nodiscard Warning: Only use -K or -E on new volumes with no existing data. Run the following command to create a EXT4 partition that takes the whole space: sudo parted /dev/sdb --script -- mkpart primary ext4 0% 100%. The -g option is very, very different from the -G option for mkfs.ext4.. Microsoft is definitely recommending changing the -G option in the best practices document, not the -g option, which is clearly discouraged from being used/changed/tweaked, as you noted from the man page.-G number-of-groups. You can get information about your filesystem by executing lsblk or lsblk --fs for more information. Format with EXT4 # Create a GPT partition table by issuing: sudo parted /dev/sdb --script -- mklabel gpt. The last 2 partitions are empty and have no filesystems as yet: $ sudo mkfs.ext4 /dev/sdb1 .. will have the same result as the previous example command, and will create an ext4 file system on /dev/sdb1, which in this example happens to be an USB flash drive. The syntax is mkfs.ext4 *partition* An example would be mkfs.ext4 /dev/sda2 where /dev/sda2 is the unformatted partition in question. In order to format a partition with an EXT4 filesystem, you need to use the “mkfs” command and specify the “ext4” filesystem. The following procedure creates an LVM logical volume and then creates an ext4 file system on that volume.
