LFCS Storage Management Practice Question
An administrator has enabled quotas on the /home filesystem by adding usrquota,grpquota to /etc/fstab and remounting. Then ran quotacheck -cug /home and it completed successfully. However, users are still able to write beyond their assigned soft limits. What step is missing?
⚠ Common exam trap
A common mix-up: candidates assume running `quotacheck -cug` both creates the quota database and activates quotas, but `quotacheck` only scans and builds the database, while `quotaon` is a separate mandatory step to enable enforcement.

Correct answer & explanation
✓
Running quotaon to activate quotas.
The missing step is activating quotas with `quotaon`. Even after configuring `/etc/fstab` with `usrquota,grpquota`, remounting the filesystem, and running `quotacheck -cug` to create the quota database files (`aquota.user` and `aquota.group`), quotas remain inactive until explicitly enabled with `quotaon`. Without this command, the kernel does not enforce quota limits, allowing users to exceed soft limits without warning.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Setting limits with edquota.
Why it's wrong here
edquota sets limits but quotaon is needed first.
- ✗
Running repquota to view quotas.
Why it's wrong here
repquota only reports quota information.
- ✗
Setting limits with setquota.
Why it's wrong here
setquota also sets limits but quotaon must be active.
- ✓
Running quotaon to activate quotas.
Why this is correct
Correct: quotaon enables quota enforcement after quotacheck.
