A system administrator needs to create a new 10-gigabyte logical volume named lv_logs from the existing volume group vg_data. Which of the following commands correctly performs this action?
vgcreate -s 10G vg_data /dev/sdb1
lvcreate -l 10240 -n lv_logs vg_data
lvcreate -L 10G -n lv_logs vg_data
lvextend -L +10G /dev/vg_data/lv_logs
The correct command is lvcreate -L 10G -n lv_logs vg_data. The lvcreate command is used to create a new logical volume. The -L option specifies the size of the new volume in standard units (G for gigabytes), the -n option specifies the name, and the final argument is the name of the volume group from which to allocate the space.
lvextend command is incorrect because it is used to increase the size of an existing logical volume, not to create a new one.vgcreate command is incorrect because it is used to create a new volume group from physical volumes, not to create a logical volume within a volume group.lvcreate -l 10240 is incorrect because the -l (lowercase L) option specifies the size in logical extents, not gigabytes. While this could potentially result in a 10GB volume if the physical extent size was exactly 1MB, the -L option is the direct and correct method for specifying size in gigabytes as requested.Bash is our AI bot, trained to help you pass your exam.
