For example, when they get 70% full then grow them so that they get 50% full? Other values? Thanks for the hints!

...hunks of, say, 16GB or more the performance should stay reasonable. In many cases, you can have a rough guess at how much space you will need in the filesystems, so it doesn't make sense to keep huge amounts of free space around.

Something else that you might want to do is count the number of journal commits that are taking place, via a command like this: perf stat -e jbd2:jbd2_start_commit -a sleep 3600 This will count the number of jbd2 commits are executed in 3600 seconds --- i.e., an hour. If you are running some workload which is constantly calling fsync(2), that will be forcing journal commits, and those turn into

Hi Alan, sorry for the journalctl output. I have now done the following:L * boot into 3.17-rc7 * mount the usb stick (recovery completed) * unmount, mount, unmount - just to be sure all is fine * started usbmon capturing on bus 3 * mount the usb stick * suspend to ram * wake up now the stick is "officially" mounted (/proc/mounts) * umount error messages pop up * try to mount more
