Red Hat/CentOS ext4 cannot format large partitions, centosext4

The RedHat/CentOS 6.5 e2fsprogs version is earlier than 1.41.12, so you cannot create a file system larger than 16 TB.

Download the latest e2fsprogs, compile and install it
Ftp://ftp.ntu.edu.tw/linux/kernel/people/tytso/e2fsprogs/

Tar zxvf e2fsprogs-1.42.10.tar.gz

Common Faults:

[Root @ localhost ~] # Mount/dev/sda1/mnt/
Mount: wrong fs type, bad option, bad superblock on/dev/sda1,
Missing codepage or helper program, or other error
In some cases useful info is found in syslog-try
Dmesg | tail or so

In linux, the format of a mobile hard disk formatted with mkfsext4 is invalid. You cannot change the file format.

What about partitions? When configuring a partition table, what type of partition file system is selected? Fdisk-l check

For example, you can perform operations on/dev/sda as follows:
Fdisk/dev/sda
P (print the partition table of this disk)
L (list supported file system types)

Partition formatting in ext4 format cannot be displayed on windows

Cannot be used. It needs to be initialized and formatted.
Sorry, I am wrong. The premise you wrote is formatting. This can be used. I think you have mounted it !!!
