Partprobe is a program that informs the operating system kernel of partition table changes, by requesting the operating system to re-read the partition table. partx: partx is telling the kernel about presence and numbering of on-disk partitions.ġ) Reloading partition table in Linux with partprobe command.

FDISK USING WIPEFS DRIVER

hdparm: hdparm provides a command line interface to various kernel interfaces supported by the Linux SATA/PATA/SAS “libata” subsystem and the older IDE driver subsystem.

blockdev: The utility blockdev allows to call block device ioctls from the command line.

partprobe: partprobe is a program that informs the operating system kernel of partition table changes, by requesting that the operating system re-read the partition table.

FDISK USING WIPEFS HOW TO

In this guide, we’ll show you how to re-load partition table without reboot in Linux using the following four commands: I would suggest you to run any of the below commands after adding a partition in Linux system to inform the OS about the partition table changes. However, the partx command works as expected on RHEL 7 systems. I have tested the below four commands on Arch Linux system and all are working fine except ‘partx’ command, because I didn’t find any information about the partition change in the ‘dmesg’ log after running the partx command. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8). Re-reading the partition table failed.: Device or resource busy Most of the time you can get the output below in virtual environment when you are performing the disk partitions: The partition table has been altered.Īt the same time when you make disk partitions, you may get the below output in the physical environment: The partition table has been altered.Ĭalling ioctl() to re-read partition table.

Visit to the following URLs to learn more about disk partitions: Please choose the desired command based on your need. In Linux, disk partitioning can be done using multiple commands and most users prefer to use fdisk or parted. These commands are to: 1) force the Kernel to reload the partition table and 2)re-populate its ids in /dev. However, we can not guarantee that it will work 100%, but it will work most of the time as per my experience and knowledge. If so, what is the solution to inform the OS about partition table changes? Most of the time the partition table will be altered successfully after the disk partition in the virtual environments (such as VMWare, Virtualbox, etc).īut things do not go as planned every time, because sometimes your system doesn’t alter the partition table with new disk information, which often happens in physical systems.

As a Linux administrator you might perform a disk partition task quite often.
