General Instructions

  • follow steps in use cases
  • when you are busy then take use-case with the fewest attendee
  • fill the report in this form [1]
  • after the report from thus event are collected, QE team will work with UDX team on qualitative and quantitative analysis, share the results with developers and reports bugs/rfes in Bugzilla, in addition summary will be sent to all the contributors

Who's available

The following cast of characters will be available testing, workarounds, bug fixes, and general discussion ...


Initial setup

  • have a Fedora 19 Beta RC2 (virtual) machine owned by you, ISO image available at [2] or [3]
  • alternatively you can use prepared image available at [4]

Text mode installation

  • Install Fedora using text mode (append text on kernel command line)
  • Text mode installation will offer you possibility to continue installation remotely using VNC, please don't use it and continue in the text mode
  • In the installer add new user john with admin rights

Create multiple Volume Groups

Multiple hard drives required
You need a machine with more than 4 disks

Action

  • Start Fedora 19 installation in graphical mode (default)
  • Use manual partitioning, choose LVM partitioning scheme
  • Create four volume groups, one volume group per disk drive
  • Create four mountpoints: /, /var, /tmp, /home and place each of them to separate volume group
  • Place swap partition to the same volume group as /

CHAP authentication against iSCSI target

CHAP
Challenge-Handshake Authentication Protocol (CHAP) authenticates a user or network host to an authenticating entity
iSCSI target
Internet Small Computer System Interface, an Internet Protocol (IP)-based storage networking standard for linking data storage facilities. An iSCSI target is often a dedicated network-connected hard disk storage device, but may also be a general-purpose computer

Setup

  • have virtual machine (VM) ready
  • prepare iSCSI volume on another VM (called here iscsi_target VM) which is reachable from VM where the installation will be performed
Note
Alternatively, you can use prepared images that can be downloaded from [5]

Preparation of iscsi_target VM

Packages needed
you need to have python-virtinst, libvirt, virt-manager and virt-viewer installed
   # virt-install -n iscsi-target -r 512 --arch x86_64 --import --os-type linux --os-variant rhel7 --disk /var/lib/libvirt/images/iscsi-target.img --serial pty --graphics spice
  • root password is fedora
  • if you want to use serial console use this command: virsh --connect qemu:///system console anaconda-usability

On iscsi_target VM do

Firewall settings
Ensure, port 3260 is available for incoming connection and there is no blocking firewall in the way between target and test machine.
  • install scsi-target-utils package and start tgtd service
   # yum install scsi-target-utils
  • create empty 4GB file
   # dd if=/dev/zero of=/root/iscsi-lun.img bs=1 count=0 seek=4G
  • add new iSCSI target, target ID 1 (tid=1)
   # tgtadm --lld iscsi --op new --mode target --tid=1 --targetname iqn.2009-02.com.example:auth.chap
  • Add a new iSCSI logical unit with lun=1 to specific target with tid=1.
   # tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 -b /dev/loop0
  • Add the address to the access lists of the target, allow connection from all initiators
   # tgtadm --lld iscsi --op bind --mode target --tid 1 -I ALL
  • Setup new user consumer with password Longsw0rd
   # tgtadm --lld iscsi --op new --mode account --user consumer --password Longsw0rd
  • Bind newly created user to iSCSI target with tid=1
   # tgtadm --lld iscsi --op bind --mode account --tid 1 --user consumer
Note
If you use provided iSCSI-target image you can ommit all steps above.
IP address is set to 192.168.100.100
  • attach iscsi-lun.img to /dev/loop0 and start tgtd
   # losetup /dev/loop0 /root/iscsi-lun.img
   # service tgtd start

Action

Install Fedora to VM using graphical user interface. In the installer:

  • Use custom partitioning scheme, select LVM
  • Search for iSCSI target and add it to the advanced & network disk section
Note
If you use provided iscsi-target image, the IP address of iSCSI target is set to 192.168.100.100
Use CHAP authentication. Username/password is consumer/Longsw0rd
  • Set up new LVM Volume Group that consists from at least one disk from Virtual Machine and at least one iSCSI target
  • boot installed system
