When umount is used, the following error occurs: deviceisbusy -- Linux Enterprise Application-Linux server application information. For more information, see. I used the following input when I got on the server today:
Df-HT
You can see that a mobile hard disk is mounted to the/mnt/USB disk directory...
Presumably the last time there was no umount
When umount is executed, the system prompts: device is busy.
Forcible: umount/dev/sdb2-f
Tip: umount2: the device or resource is busy.
Umount:/mnt/usbdisk: device is busy
Someone is using... to view the same usage: fuser-m/mnt/usbdisk
There are 6406 processes in use ..
Pss aux | grep 6406
Kill again
Then umount prompts whether it still fails...
Then fuser-k/mnt/USB disk
Tip:
/Mnt/usbdisk/: 6406c
No automatic removal. Please use umount/mnt/usbdisk
