Creating ext3 file system

Filesystem size: 2 TB to 32 TB. The first thing to do is to identify the name of the device or partition where you want to create the file system.

Now let me tell you one thing that in linux machines the naming convention are like this. Or if you want to create a new partition out of your disk then you need to run the below command instead of the above.

Note: identify your disk or partition name from fdisk -l and if you want to create a partition inside a disk then pass the disk's name as an argument to fdisk. Now we will use the "n" option because we want to create a new partition. After using the n option you will be told to select the first cylender just press enter there as the system will by itself select the first cylinder available.

Now enter the required size of your partition like as shown below:. Now press enter after entering the desired size value. Now give the command "w" to write the partition infor to the partition table. Now you can mount the newly created partition wherever you want and start using the filesystem. Now one of the main feature that is different in ext3 filesystem is the jounalling of the filesystem. For understanding journing you can reffer this post. Max file system size: 2 TB to 32 TB. One more interesting fact is that if you want journalling mechanism to be in your ext2 filesystem then you can easily convert it to ext3.

Now lets understand how to create ext3 filesystem:. And as told before you can convert an ext2 filesystem without data loss by the following command. Note: first unmount the file system, then run the below command.

Availability After an unexpected power failure or system crash also called an unclean system shutdown , each mounted ext2 file system on the machine must be checked for consistency by the e2fsck program.

This is a time-consuming process that can delay system boot time significantly, especially with large volumes containing a large number of files. During this time, any data on the volumes is unreachable. It is possible to run fsck -n on a live filesystem. However, it will not make any changes and may give misleading results if partially written metadata is encountered. Finally, there is the option to remount the filesystem as read only. All pending metadata updates and writes are then forced to the disk prior to the remount.

This ensures the filesystem is in a consistent state, provided there is no previous corruption. It is now possible to run fsck -n. The journaling provided by the ext3 file system means that this sort of file system check is no longer necessary after an unclean system shutdown.

For example, if you add a new disk drive to the system, you may want to partition the drive, and use the ext4 file system. Now select ext4 as the file system type. Set the start and end to establish the size of the partition. Next, you need to properly format the new partition with the ext4 file system type using the mkfs or mke4fs command as follows. We can label the partition using the e4label and e2label commands as follows.

Now we are using df command to list all file systems on our system together with their sizes in a human-readable format -h , and their mount points and file system types -T :. The last entry is for our newly created ext4 filesystem and you can now use it to store your data. In this blog, we show how to create a new ext4 file system partition and how to mount it.

I hope this blog helps you with the creation and mounting of the ext4 file system even you can try by yourself to create an ext3 file system. Enter your email address to subscribe our blog and receive e-mail notifications of new posts by email.
