You want to create a new LUN, LUN ID =1, on a new target, target ID = 2.
Inspect the current state of targets and LUNs in the output from tgt-admin --s. The output is filtered to show only target and LUN associations.
[root@EDFAR9P0 init.d]# tgt-admin --s | egrep --i 'target|lun'
Target 1: iqn.2013-03.com.example.mypc:1
LUN information:
LUN: 0
LUN: 1
LUN: 2
LUN: 3
You want to add a new LUN to a new target by using the /iSCSIsharedDisk/physDisk4.img disk image file.
Which two options would you use to do this?
Examine these commands and their output:
# mount | grep xfs
/dev/mapper/vg_xfs_xfs1 on /xfs1 typr xfs (rw, quota_
# xfs_quota --x --c 'enable --u' /xfs1
# xfs_quota --x --c 'enable --g' /xfs1
XFS_QUOTAON: Invalid argument
Identify the reason for the ''Invalid argument'' error.
You have a mounted mirrored btrfs file system in RAID-1 on /btrfs:
# btrfs filesystem show
Label: 'Btrfs' uuid: 7bfe3239-47ee-442b-b9f8-49f88b6b1be4
Total devices 2 FS bytes used 250.46MB
devid 2 size 4.88GB used 1.54GB path /dev/sdd
devid 1 size 4.88GB used 1.54GB path /dev/sdc
You found an error on one device:
#btrfs scrub start --B --d --r /btrfs

Examine the virt-install command.
# virt-install \
--connect qemu:///system\
--virt-type kvm \
-- name test \
-- ram 500 \
--disk path =/var/lib/libvirt/images/test.img, size=4
--cdrom /home/user01/DownLoads/OracleLinux-R6-U5-Server-x86_64-dvd.iso \
--os-variant oe16
