Error message: "dev/sda1 is apparently in use by the system..."

acoma · 2017-11-20 23:48:23

Hi all,

in the very first steps of the instal process, I've just partitioned my disks 1 root 1 swap, and when I type the command "mkfs.ext4 /dev/sda1" to format it, it says the message "dev/sda1 is apparently in use by the system: will not make a filesystem here!"

Can someone tell me the reason behind this ?

I'm booting on a 32gb USB on a Asus ux301-la.

Thanks to all

Are you sure /dev/sda1 is the correct partition? The live media also has partitions which appear under /dev/.

hello, thanks for your answer. yes I typed first "fdisk -l" to list the disks. I tryied the mkfs.ext4 command with all of them anyway and the message is the same

Please post the output of the following in code tags.

sda and sdb are part of a raid array. Are you intending to use raid?

Also please use code tags for terminal output. The link "BBCode" below the text area explains what they are.
