XK0-006 Practice Question: A SysAdmin is investigating a server that has…
A SysAdmin is investigating a server that has become unresponsive. The server was working fine, but after a recent update, it hangs during boot, showing 'A start job is running for /dev/mapper/rootvg-rootlv (xxs / no limit)'. This indicates a filesystem check is taking long. What is the most efficient way to skip the fsck and boot quickly?
⚠ Common exam trap
A common mix-up: candidates confuse the permanent /etc/fstab sixth field (which controls fsck frequency) with the temporary kernel parameter, or incorrectly think that Ctrl+D or single-user mode will skip the check, when in fact they do not bypass the stuck job.
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
✓
Use the kernel parameter 'fsck.mode=skip'.
The kernel parameter 'fsck.mode=skip' instructs systemd to skip all filesystem checks during boot, allowing the server to bypass the stuck fsck job and start quickly. This is the most efficient method for a one-time skip without permanently altering configuration files.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
At boot, press Ctrl+D to continue.
Why it's wrong here
Ctrl+D is not a standard method to skip fsck; it usually sends EOF.
- ✗
Boot into single-user mode and run fsck.
Why it's wrong here
This runs the filesystem check, not skipping it.
- ✓
Use the kernel parameter 'fsck.mode=skip'.
Why this is correct
This parameter temporarily skips all filesystem checks for the current boot.
- ✗
Edit /etc/fstab to set the sixth field to 0 for the root filesystem.
Why it's wrong here
This permanently disables fsck on that filesystem, which may be undesirable.
