Partprobe Command Showing Error

Hi,

I’ve created a new partition on /dev/sda on my CentOS machine after which fdisk -l gives output as:
Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 3500 28009327+ 83 Linux
/dev/sda3 3501 6527 24314377+ 83 Linux

Now, when I run partprobe I get the following error:
Error: Error informing the kernel about modifications to partition
/dev/sda3 — Device or resource busy. This means Linux won’t know about any changes you made to /dev/sda3 until you reboot — so you shouldn’t mount it or use it in any way before rebooting. Warning: The kernel was unable to re-read the partition table on /dev/sda
(Device or resource busy). This means Linux won’t know anything about the modifications you made until you reboot. You should reboot your computer before doing anything with /dev/sda.

I’m using parted rpm version “parted-1.8.1-29.el5”. Is it some issue with this version or with the way I’m using this command?

Thanks, Anumeha

  • In my experience, this is normal behavior…it’s not any different than if you used fdisk, instead.

    You’re modifying the partition table on the boot drive, and, if I recall correctly, there isn’t a mechanism for the kernel to reread the partition table of the boot drive.

    Long story short, you’ll need to reboot.

  • Thanks for the reply…

    But isn’t it true that if I use partprobe command, I don’t need to reboot my machine for kernel to read partition changes?
