Interestingly (well, perhaps not really) this is very easy. In my case, I’m hoping that the migration will lead to faster fsck times (currently it’s taking about an hour, which is somewhat excessive, each time the server crashes for whatever reason). In my case, the filesystem is /dev/md0 and mounted at /home – change the… Continue reading Migrating an ext3 filesystem to ext4 (Debian Squeeze)
