I am considering setting the reserved block percentage to 0% (
tune2fs -m 0 /dev/sdb1) for an
ext4 partition. The partition is only used by non-privileged users anyway.
Let's say I mistakenly fill up the partition to 100% and the filesystem becomes corrupt. Does
fsck require some free disk space to be able to run? I obviously would like to be able to repair the file system if it breaks.
