Linux verify disk activities

 

 

$ sudo apt-get install iotop

$ sudo iotop -a
$ sudo iotop -oPa -d 2  #more specific
 

$ iostat  #activity by sda, sdb, etc.
 

jbd2 is a kernel thread that updates the filesystem journal.

Get create/birth date from files

$ stat wakeup.txt  #get the inode

$ df -h wakeup.txt #get device name sdxy

$ sudo debugfs -R 'stat <586205>' /dev/sda1
