Reset your serverX system. Run the script lab fs setup before starting the exercise.

1. A new partition with a file system has been added to the second disk (vdb) on your serverX machine. Mount the newly available partition by UUID at the newly created mount point /mnt/newspace.

   1. Use the blkid to discover the UUID of the newly added partition, vdb1, on serverX.

      [root@serverX ~]# blkid
      /dev/vda1: UUID="46f543fd-78c9-4526-a857-244811be2d88" TYPE="xfs" 
      /dev/vdb1: UUID="7c5e3fbb-34eb-4431-a4a5-9b887c1b6866" TYPE="xfs"

   2. Create the mount point /mnt/newspace on serverX.

      [root@serverX ~]# mkdir /mnt/newspace

   3. Mount the file system by UUID on the /mnt/newspace directory of the serverX machine.

      [root@serverX ~]# mount UUID="7c5e3fbb-34eb-4431-a4a5-9b887c1b6866" /mnt/newspace

2. Change to the /mnt/newspace directory and create a new directory, /mnt/newspace/newdir, with an empty file, /mnt/newspace/newdir/newfile, on serverX.

   1. Change to the /mnt/newspace directory on serverX.

      [root@serverX ~]# cd /mnt/newspace

   2. Create a new directory, /mnt/newspace/newdir, on serverX.

      [root@serverX newspace]# mkdir newdir

   3. Create a new empty file, /mnt/newspace/newdir/newfile, on serverX.

      [root@serverX newspace]# touch newdir/newfile

3. Unmount the file system mounted on the /mnt/newspace directory on serverX.

   1. Try to unmount /mnt/newspace while the current directory on the shell is still /mnt/newspace on serverX.

      [root@serverX newspace]# umount /mnt/newspace

   2. Change the current directory on the shell to /root.

      [root@serverX newspace]# cd
      [root@serverX ~]# 

   3. Successfully unmount /mnt/newspace on serverX.

      [root@serverX ~]# umount /mnt/newspace
