This article mainly introduces "what to do with the warning message when using the fdisk command to partition in Linux". In the daily operation, I believe that many people have doubts about what to do when they use the fdisk command to partition in Linux. The editor consulted all kinds of materials and sorted out a simple and useful method of operation. I hope it will be helpful for you to answer the question of "what to do when you use the fdisk command to partition in Linux?" Next, please follow the editor to study!

When you use the fdisk command to partition in Linux, you sometimes encounter "WARNING: Re-reading the partition table failed with error 16: Device or resource busy.The kernel still uses the old table.The new table will be used at the next reboot." This kind of alarm message. As shown below

[root@localhost ~] # fdisk / dev/sde

The number of cylinders for this disk is set to 18928.

There is nothing wrong with that, but this is larger than 1024

And could in certain setups cause problems with:

1) software that runs at boot time (e.g.old versions of LILO)

2) booting and partitioning software from other OSs

(e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): P

Disk / dev/sde: 155.6 GB, 155692564480 bytes

255 heads, 63 sectors/track, 18928 cylinders

Last cylinder or + size or + sizeM or + sizeK (18276-18928, default 18928):

Using default value 18928

Command (m for help): W

The partition table has been altered!

Calling ioctl () to re-read partition table.

WARNING: Re-reading the partition table failed with error 16: Device or resource busy.

The kernel still uses the old table.

The new table will be used at the next reboot.

Syncing disks.

The newly created partition information can not be seen by using the fdisk command at this time, so you can use the partprobe command to solve this problem without rebooting the system, because partprobe can make kernel read the partition information again, thus avoiding restarting the system.

Partprobe-inform the OS of partition table changes

DESCRIPTION

This manual page documents briefly the partprobe command.

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.

At this point, the study on "what to do when there is a warning message when using the fdisk command in Linux" is over. I hope to be able to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
