RHCSA Rapid Track

Instructions

1. Log in to servera as the student user and switch to the root user.

   student@workstation ~]$ ssh student@servera
   ...output omitted...
   [student@servera ~]$ sudo -i
   [sudo] password for student: student
   [root@servera ~]#

2. Create an msdos disk label on the /dev/vdb device.

   [root@servera ~]# parted /dev/vdb mklabel msdos
   Information: You may need to update /etc/fstab.

3. Add a 1 GB primary partition. For correct alignment, start the partition at the 2048 sector. Set the partition file-system type to XFS.

   1. Use parted interactive mode to create the partition.

      [root@servera ~]# parted /dev/vdb
      GNU Parted 3.4
      Using /dev/vdb
      Welcome to GNU Parted! Type 'help' to view a list of commands.
      (parted) mkpart
      Partition type?  primary/extended? primary
      File system type?  [ext2]? xfs
      Start? 2048s
      End? 1001MB
      (parted) quit
      Information: You may need to update /etc/fstab.

      Because the partition starts at the 2048 sector, the previous command sets the end position to 1001 MB to get a partition size of 1000 MB (1 GB).

      Alternatively, you can perform the same operation with the following non-interactive command: parted /dev/vdb mkpart primary xfs 2048s 1001 MB

   2. Verify your work by listing the partitions on the /dev/vdb device.

      [root@servera ~]# parted /dev/vdb print
      Model: Virtio Block Device (virtblk)
      Disk /dev/vdb: 5369MB
      Sector size (logical/physical): 512B/512B
      Partition Table: msdos
      Disk Flags:
      
      Number  Start   End     Size    Type     File system  Flags
       1      1049kB  1001MB  1000MB  primary

   3. Run the udevadm settle command. This command waits for the system to register the new partition, and returns when it is done.

      [root@servera ~]# udevadm settle

4. Format the new partition with the XFS file system.

   [root@servera ~]# mkfs.xfs /dev/vdb1
   meta-data=/dev/vdb1              isize=512    agcount=4, agsize=61056 blks
            =                       sectsz=512   attr=2, projid32bit=1
            =                       crc=1        finobt=1, sparse=1, rmapbt=0
            =                       reflink=1    bigtime=1 inobtcount=1
   data     =                       bsize=4096   blocks=244224, imaxpct=25
            =                       sunit=0      swidth=0 blks
   naming   =version 2              bsize=4096   ascii-ci=0, ftype=1
   log      =internal log           bsize=4096   blocks=1566, version=2
            =                       sectsz=512   sunit=0 blks, lazy-count=1
   realtime =none                   extsz=4096   blocks=0, rtextents=0

5. Configure the new file system to mount to the /archive directory persistently.

   1. Create the /archive directory.

      [root@servera ~]# mkdir /archive

   2. Discover the UUID of the /dev/vdb1 device. The UUID in the output is probably different on your system.

      [root@servera ~]# lsblk --fs /dev/vdb
      NAME   FSTYPE FSVER LABEL UUID                                 FSAVAIL FSUSE% MOUNTPOINTS
      vdb
      └─vdb1 xfs                881e856c-37b1-41e3-b009-ad526e46d987

   3. Add an entry to the /etc/fstab file. Replace the UUID with the one that you discovered from the previous step.

      ...output omitted...
      UUID=881e856c-37b1-41e3-b009-ad526e46d987 /archive xfs defaults  0 0

   4. Update the systemd daemon for the system to register the new /etc/fstab file configuration.

      [root@servera ~]# systemctl daemon-reload

   5. Mount the new file system with the new entry in the /etc/fstab file.

      [root@servera ~]# mount /archive

   6. Verify that the new file system is mounted on the /archive directory.

      [root@servera ~]# mount | grep /archive
      /dev/vdb1 on /archive type xfs (rw,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota)

6. Reboot servera. After the server rebooted, log in and verify that the /dev/vdb1 device is mounted on the /archive directory. When done, log out from servera.

   1. Reboot servera.

      [root@servera ~]# systemctl reboot
      Connection to servera closed by remote host.
      Connection to servera closed.
      [student@workstation ~]$

   2. Wait for servera to reboot and log in as the student user.

      [student@workstation ~]$ ssh student@servera
      ...output omitted...
      [student@servera ~]$

   3. Verify that the /dev/vdb1 device is mounted on the /archive directory.

      [student@servera ~]$ mount | grep /archive
      /dev/vdb1 on /archive type xfs (rw,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota)

   4. Return to the workstation machine as the student user.

      [student@servera ~]$ exit
      logout
      Connection to servera closed.
      [student@workstation ~]$
