Bitrix Virtual Appliance

You should place specific partitions at the separate disks due to the majority of disk space being occupied by site content and reserve copies, located in /home/bitrix, as well as by the database, located in /var/lib/mysql.

Let's overview this case with an example, when a folder /home is transferred with site contents and backup copies to a separate disk.

• Add a new disk of needed size inside the Virtual Appliance settings hardware list. Perform all the actions, listed below, under the root user administrator account:

  

  

• After the disk was added, a server re-load may be required to initialize it. You can see the new disk and its assigned letter designation via this command:
  

  fdisk -l

  

• Launch the fdisk utility for work with the /dev/sdb disk:

  fdisk /dev/sdb

  Create a new partition via the n command:

  • new (primary partition) - p command and Partition number (1-4): 1;
  • first and the last sectors should be selected by default - this way, a partition will be created, using all the free space on the disk:

  

To save changes on the disk and to exit from the fdisk, enter the w command.

• After partition table are saved, format new partition and transfer information from /home to it:

  CentOS 6

  mkfs.ext4 /dev/sdb1 
  mount /dev/sdb1 /mnt 
  service httpd stop 
  service nginx stop
  mv -f /home/* /mnt 
  umount /mnt
  

  CentOS 7

  mkfs.ext4 /dev/sdb1 
  mount /dev/sdb1 /mnt 
  systemctl stop httpd.service
  systemctl stop nginx.service
  mv -f /home/* /mnt 
  umount /mnt
  

• Text step, define UUID for new disk:

  blkid
  /dev/sda1: UUID="99066558-ba04-465c-9962-e827aa2928ec" TYPE="ext4" 
  /dev/sda2: UUID="8ea38ef9-1ee5-423b-a013-15fd603a678e" TYPE="swap" 
  /dev/sda3: UUID="08ec5c65-8fd8-47ac-a998-d81195c8f964" TYPE="ext4" 
  /dev/sdb1: UUID="b2e58731-b621-4bd5-909a-afe3bb5dd8a1" TYPE="ext4"
  

  and add the record (in this example: UUID=b2e58731-b621-4bd5-909a-afe3bb5dd8a1) about it in /etc/fstab (instead of UUID, device name /dev/sdb also can be used):

  

• The only thing that is left, is to import a new disk and to launch previously stopped services:

  CentOS 6

  mount /home 
  service httpd start 
  service nginx start 
  

  CentOS 7

  mount /home 
  systemctl start httpd.service
  systemctl start nginx.service
  

Adding disks in other virtualization environment or directly on a physical server is performed in a similar manner.
