people were relatively happy with the ~5 second vulnerability window in ext3, but are getting bit by the ~60 second vulnerability window that ext4 defaulted to.
Well, if the 5-second window had left my systems vulnerable to data corruption (in the form of zero-length files) I know I would not
have been happy. After all that 5-second window happens every 5 seconds, so you are virtually guaranteed to run into the problem if it exists, whatever the window size.
I remember my horror after finding out that XFS had lost my data, and I read about XFS devs hiding behind the standard "journalling filesystems only make guarantees about the metadata". "The metadata? fsck the metadata! What I want is my wretched data back!" Now it is all coming back in waves.
