Question #: 25
Topic #: 8

The journald entries have filled a Linux machine's /var volume. Which of the following is the best command for a systems administrator to use to free up the disk space occupied by these entries?

Ajournalctl ---rotate
journalctl --vacuum-time=ls

Bsystemctl stop systemd-journald
systemctl start systemd-journald

Crm -rf /var/log/journal
systemctl restart systemd-journald

Dpkill -HUP systemd-journald
systemctl restart systemd-journald

Show Suggested Answer

Suggested Answer: B

systemctl stop systemd-journald systemctl start systemd-journald is the best approach among the given options. Stopping and starting the systemd-journald service can help in managing the disk space used by journal logs without manually deleting log files or using more aggressive cleanup methods. This method ensures that log management is handled gracefully by the system's own services.

You're right, there could be important files in the journal. Maybe rotating them with journalctl would be safer.

But won't using rm -rf be risky and could potentially delete necessary files?

I think B) systemctl stop systemd-journald and then starting it again could also work.

I disagree, I believe option C) rm -rf /var/log/journal is the best choice to free up disk space.

I think option D) pkill -HUP systemd-journald seems like a good solution, as it restarts the journal service.

Using rm -rf can be risky as it deletes files forcefully, it's better to rotate the journal entries instead.

But what about option C) rm -rf /var/log/journal? Wouldn't that quickly free up space as well?

Option C looks more promising. Removing the journal directory and restarting the service could potentially clear out all the journal entries and free up space.

I agree, Option A seems a bit unclear. Option B just stops and starts the journald service, which might not actually free up any space.

Well, let's take a look at the options. Option A seems to involve some commands I'm not familiar with, and I'm not sure if rotating and vacuuming the journal is the best approach.
