I am days before the RHCSA exam and i have noticed i still haven't been able to successfully run partprobe successfully after months on testing and testing and testing..not a single time
i have tried
partprobe
partprobe /dev/sdx where sdx is drive name
it never works i get warning the kernel failed to re-read the partititon table on /dev/sdx (device or resource busy) as a result it may not reflect all of your changes until after reboot
What do i do?
yes parted is installed
i have tried
partprobe
partprobe /dev/sdx where sdx is drive name
it never works i get warning the kernel failed to re-read the partititon table on /dev/sdx (device or resource busy) as a result it may not reflect all of your changes until after reboot

Partprobe never worked for me, reboot will find and set up your new drive. Sometimes a reboot will give you a few minutes to think about your next step.

Why are you doing the partprobe for the RHCSA anyway ?
I have done the exam and train students for this exam as well. I seem to miss the point -

Under the RHCSA objectives at: Red Hat | Red Hat Certified System Administrator (RHCSA) Exam objectives (EX200)
Configure local storage- List, create, delete, and set partition type for primary, extended, and logical partitions.
- Create and remove physical volumes, assign physical volumes to volume groups, and create and delete logical volumes.
- Create and configure LUKS-encrypted partitions and logical volumes to prompt for password and mount a decrypted file system at boot.
- Configure systems to mount file systems at boot by Universally Unique ID (UUID) or label.
- Add new partitions and logical volumes, and swap to a system non-destructively.

so i don't have to reboot? partprobe helps to discover the newly created partition without having to reboot -

thats the thing why can't i avoid reboot? reboot can eat out of my precious time for the exam and especially when i don't want something messed up or the the unforseen happening
i mean why is the partprobe command created then? if it doesn't freaking work or at least when its not consistent? I see videos where it works and i get so annoyed when it never worked for me -

It sounds like you still have a file system mounted somewhere on that disk as parted 2.1 will fail on any partitions still in use from a file system. Make sure you are running it on a disk that has all file systems on that disk dismounted.Jumping on the IT blogging band wagon -- http://www.jefferyland.com/ -

Not sure what you mean...but lets say i have one sda disk and have 7 partitions(primary and logical) and afetr creating the 7th partition i want to run partprobe...so what do i do? unmount all the other 6 partitions? before runningpartprobe?
Not sure what you mean...will appreciate it if you can give a little more details
thanks -
