ext3 incluye journalism por defecto, encontré esto por ahi te sirve: Fuente: http://www.netadmintools.com/art178.html SET JOURNAL MODE MOUNT OPTIONS There are three mount options for the journal modes. They are: data=writeback -- does no journalling of data; metadata only. fastest. data corruption possible in system crash. data=ordered -- default. strictly speaking only journals metadata but uses transactions to protect data as well. slightly slower than writeback mode. Because of the way the blocks to be written to disk are ordered in this mode, it offers all the protection of full data journalling mode when files are being appended to; corruption is possible when files are being overwritten. data=journal -- full journalling of data and metadata. Should be slowest because data is written twice, once to journal & once to final location. However some tests have shown that its performance surpasses the other two modes in busy interactive environments where disks are being read from & written to at same time. Also requires the largest disk footprint for journal. Example: Change journal mode to data=writeback for a filesystem containing database files where i/o performance has to be great. Risk of corruption is mitigated by the fact that the db is keeping redo logs on separate filesystem. Not that I'm recommending this. -- Sebastián Bassi (セバスティアン). Diplomado en Ciencia y Tecnología.
