A high-performance computing cluster needs a logical volume that stripes data across four physical volumes to maximise I/O throughput. Which command creates this LV?

lvcreate -n lvstriped -L 100G vgdata

lvcreate -s -n lvstriped -L 100G vgdata

lvcreate -i 4 -I 64 -n lvstriped -L 100G vgdata

lvcreate -m 1 -n lvstriped -L 100G vgdata

What is the purpose of the pvmove command?

To create a new physical volume

To display physical volume information

To relocate physical extents from one physical volume to another

An administrator creates a thin pool named thinpool in vgdata with a virtual size of 2 TB and a physical size of 500 GB. Which command creates a thin volume named thinvol with a virtual size of 200 GB?

lvcreate -L 200G -T vgdata/thinpool -n thinvol

lvcreate -T vgdata/thinpool -n thinvol -l 200

lvcreate -V 200G -T vgdata/thinpool -n thinvol

lvcreate -V 200G -n thinvol vgdata
