H A Djournal.rst6 Introduced in ext3, the ext4 filesystem employs a journal to protect the
8 to 10,240,000 file system blocks (see man mke2fs(8) for more details on journal
12 cache, a record of the data being committed is also written to the journal. At
13 some later point in time, the journal code writes the transactions to their
16 crash during the second slow write, the journal can be replayed all the
18 gets written through the journal to the disk. The effect of this is to
23 through the journal. This means that file data blocks are /not/
26 option to control journal behavior. If ``data=journal``, all data and
27 metadata are written to disk through the journal. This is slower but
29 disk before the metadata are written to disk through the journal.
