I have Ubuntu 10.04 dedicated server with SSD drive. Hence I want to disable the file system journal.
Normally this can be done like this "tune2fs -O ^has_journal /dev/md2". However the root file system is in read-write mode so tune2fs prints an error. The "-f" does not work.
Maybe during boot there is some script which is executed having root file system mounted read-only. So I can add above command to that script.
BTW I can reinstall OS but ext2 isn't available. A server provider admin web page doesn't allow to pass create partition options when reinstalling OS.
