LPIC-2 File Sharing and Samba Practice Question
Exhibit
Refer to the exhibit. $ smbstatus -S Service pid machine Connected at ------------------------------- data 1234 client1 Mon Jan 20 10:00:00 2025 $ pdbedit -L -v | grep -A5 "Unix username" Unix username: alice NT username: EXAMPLE\\alice Account Flags: [U ] User SID: S-1-5-21-123456789-1001 Primary Group SID: S-1-5-21-123456789-513 Full Name: Alice Home Directory: \\server\\alice Home Drive: H: Script Path: \\server\\netlogon\\alice.bat Profile Path: \\server\\profiles\\alice
A user alice is connected to the 'data' share via smbd, but a file is locked. Which command can forcibly close the file?
⚠ Common exam trap
Many candidates confuse `smbcontrol` with other Samba utilities or think that restarting the entire Samba service (nmbd or smbd) is the only way to clear locks, overlooking the targeted `close-share` command.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
smbcontrol smbd close-share data
`smbcontrol smbd close-share data` sends a message to the smbd process to forcibly close all open files on the 'data' share, releasing any locks held by users like alice. This command directly targets the Samba daemon's internal state without disrupting the entire service or other shares.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
smbpasswd -L -e alice
Why it's wrong here
smbpasswd manages passwords, not locks.
- ✓
smbcontrol smbd close-share data
Why this is correct
smbcontrol can interact with smbd to close a share.
- ✗
systemctl restart nmbd
Why it's wrong here
nmbd is for NetBIOS, not file locks.
- ✗
kill -9 $(pgrep smbd)
Why it's wrong here
Kills all smbd processes, disruptive.
