물리적 크기 5GB, 논리적 크기 50GB의 VDO 기반 논리 볼륨을 생성한 다음 XFS로 포맷합니다.
Reveal Solution Discussion 0Correct Answer:
See the solution below in Explanation.
Explanation:
Solution:
dnf install -y vdo kmod-kvdo lvm2
pvcreate /dev/sdc
vgcreate vdo-volumegroup /dev/sdc
lvcreate --type vdo -n vdo-logicalvolume -L 5G -V 50G vdo-volumegroup/vdo-pool
mkfs.xfs /dev/vdo-volumegroup/vdo-logicalvolume
Detailed Explanation:
* VDO provides compression and deduplication.
* -L 5G sets the physical backing size.
* -V 50G sets the logical exposed size.
* This allows thin, optimized storage presentation.
* The exact commands are taken from the RHCSA dataset embedded in the uploaded lab HTML.
