Partitioning additional hard disk on UCP Advisor VM

You must add and partition a hard disk of 150 GB if you want to provision an operating system on servers on a upgraded UCP Advisor setup.

1. Add the hard disk to the UCP Advisor VM.
2. Using SSH log on to the UCP Advisor VM as a root user.
3. Identify the newly added hard disk. Enter:

   lsblk

   Example:

   [root@UCP-LP ~]# lsblk
   NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
   sda           8:0    0   800G  0 disk 
   ├─sda1        8:1    0   953M  0 part /boot/efi
   ├─sda2        8:2    0     2G  0 part /boot
   └─sda3        8:3    0 797.1G  0 part 
     ├─ol-root 253:0    0 756.1G  0 lvm  /
     ├─ol-swap 253:1    0     1G  0 lvm  
     └─ol-home 253:2    0    40G  0 lvm  
   sdb           8:16   0   200G  0 disk 
   sdc           8:32   0   150G  0 disk 

   In the above example, sdc is the newly added hard disk.
4. Partition the hard disk. Enter:

   fdisk /dev/sdc

   Enter the following values when prompted:

   • Enter n to create a new partition.
   • Select p for primary disk.
   • Press Enter to accept the default partition number and the start and the end sectors.
   • Enter w to save the changes and exit.
5. Verify the partition. Enter:

   lsblk

   Example:

   [root@UCP-LP dev]# lsblk
   NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
   sda           8:0    0   800G  0 disk 
   ├─sda1        8:1    0   953M  0 part /boot/efi
   ├─sda2        8:2    0     2G  0 part /boot
   └─sda3        8:3    0 797.1G  0 part 
     ├─ol-root 253:0    0 756.1G  0 lvm  /
     ├─ol-swap 253:1    0     1G  0 lvm  
     └─ol-home 253:2    0    40G  0 lvm  
   sdb           8:16   0   200G  0 disk 
   sdc           8:32   0   150G  0 disk 
   └─sdc1        8:33   0   150G  0 part 

6. Format the new partition with XFS. Enter:

   mkfs.xfs /dev/sdc1

   Example:

   [root@UCP-LP dev]# mkfs.xfs /dev/sdc1
   meta-data=/dev/sdc1              isize=512    agcount=4, agsize=2621376 blks
            =                       sectsz=512   attr=2, projid32bit=1
            =                       crc=1        finobt=1, sparse=1, rmapbt=0
            =                       reflink=1    bigtime=0 inobtcount=0
   data     =                       bsize=4096   blocks=10485504, imaxpct=25
            =                       sunit=0      swidth=0 blks
   naming   =version 2              bsize=4096   ascii-ci=0, ftype=1
   log      =internal log           bsize=4096   blocks=25600, version=2
            =                       sectsz=512   sunit=0 blks, lazy-count=1
   realtime =none                   extsz=4096   blocks=0, rtextents=0
   

7. Create the folder for mounting the hard disk. Enter:

   [root@UCP-LP dev]# mkdir -p /var/ucpadvisor/canonical-maas

8. Mount the hard disk to the new folder. Enter:

   [root@UCP-LP dev]# mount /dev/sdc1 /var/ucpadvisor/canonical-maas

9. Preserve the mount. Enter:

   echo "/dev/sdc1 /var/ucpadvisor/canonical-maas xfs defaults 0 0" | sudo tee -a /etc/fstab

10. Reboot the server.
11. Verify if the mount was successful. Enter:

    df -h |grep maas

    Example:

    /dev/sdc1 150G  2.5G  148G 2% /var/ucpadvisor/canonical-maas
