A technician is using the interactive fdisk utility on /dev/sdb to prepare a new physical volume for LVM. After creating the partition with 'n', which fdisk command is used to change the partition's system ID to 'Linux LVM' (8e) before writing the changes?
- At
- Bl
- Cp
- Dw
Show answer & explanationAnswer & explanation
Correct answer: A. t
Within fdisk's interactive menu, 't' changes the partition's hex system ID/type. 'p' prints the current table, 'w' writes the changes to disk, and 'l' lists all known partition type codes.
Why the other options are wrong
- B. Lists known type codes for reference, but does not apply one.
- C. Prints the current partition table; does not change type.
- D. Writes changes to disk; must be run after setting the type.
fdisk partition type change
Within fdisk's interactive menu, 't' sets or changes the hex system ID of a partition, such as 8e for Linux LVM.
- 'n' creates a new partition
- 't' changes partition type code (e.g., 8e=Linux LVM)
- 'w' writes changes and exits
- 'l' lists all type codes
Memory trick: Type comes before Write: set the Tag then Write it
