Chapter 3. Disks and Partitioning > Answers to Review Questions
Answers to Review Questions
| 1. | The print option is used with both the fdisk and parted commands to display the current partition tables. |
| 2. | The partprobe command forces the kernel to reread the partition table. You should always call it after making any changes to your system partitions. |
| 3. | When you exit the parted utility, all your changes are automatically written to disk. With the fdisk command, you need to manually write your changes to disk for them to take effect. |
| 4. | RAID 0 (Striping), RAID 1 (Mirror), and RAID 5 (Striping with parity). |
| 5. | cat /proc/mdstat |
| 6. | This is actually a trick question because the answer could go either way. In this chapter, we discussed only software RAID setups, in which case the answer is no. If, however, you were using a hardware RAID 5, the answer would be yes. |
| 7. | Physical volumes, volume groups, and logical volumes. |
| 8. | If you shrink a volume group or logical volume, there is a chance you could lose data depending on how much you shrink the volume. |
| 9. | You have the flexibility to resize and add new volumes on the fly. With basic partitions, any time that you want to make a change, you need to destroy the partition and create it again. |
| 10. | lvdisplay |
