Hello,
I want to recover a file from my server.
I used extundelete.
extundelete --restore-file /home/admin/admin_backups/filename.tar.gz /dev/vda1
but I get error.
I need to:
To mount it in read only mode:
[test@server ~]$ sudo mount -o remount,ro /dev/sda6
OR to umount the device:
[test@server ~]$ umount /dev/sda6
but I get error in mount and umount.
umount: /: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
