disk space is cheap → this becomes an infuriating answer. Is cheap where ? For who ? Whatever price it is, one might want to use it for something else than log ( on a desktop pc ). Here https://answers.launchpad.net/ubuntu/+source/systemd/+question/691873 is another example of what may happen. Less than 4GB but above 10% of remaining space. This led to system complaining about storage. Shouldn't this « journal » be set by default to free space automatically on desktop computer ? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1790205 Title: systemd journals take up a lot of space, and it's not obvious how much is used, and what the upper limit is.

So, as has been previously stated here, and as is documented in section 5 of the journald.conf man page (install man-db, run 'man 5 journald.conf'), journald will, by default, limit the journals' disk allocation to either a maximum of 10% of available disk space, or to the absolute size of 4GB, whichever is lower. Example 1: You have a 120 GB disk, 70 GB are in use, leaving 50 GB. 10% of 50 GB are 5 GB, but the absolute value of 4 GB is lower, so journald will at most take 4 GB storage on this system (and dynamically less, if the disk grows fuller). Example 2: You have a 20 GB disk, 12 GB are in use, leaving 8 GB. 10% of 8 GB are 800 MB, which is less than 4 GB, so journald will at most take 800 MB storage on this system (and dynamically more or less, if disk allocation changes). Benjamin is now reporting 4.1 GB allocated, which is more than 4 GB, and with the details above, this is unexpected. What could be the reason? These limits are applied both when journald starts, and when vacuuming takes place. So if Benjamins' logs have grown by 100 MB since journald started, this can easily explain this situation. They will be reduced to 4 GB (or less, if the disk runs full) again next time vacuuming takes place (such as when journald is restarted). So unless these limits are considered a problem (why? disk space is cheap, and you can modify them as needed if you're on a special (embedded?) platform), I don't see a problem here. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1790205 Title: systemd journals take up a lot of space, and it's not obvious how much is used, and what the upper limit is.

Same issue on Bionic, installed May 15 (2 months ago): ➜ ~ sudo journalctl --disk-usage Archived and active journals take up 4.1G in the file system. My logs are definitely clogged with endless JavaScript errors from gnome-shell. Something I would not expect to slowly consume all disk space.
