Scarecrow Man Posted December 12, 2005 Report Share Posted December 12, 2005 I understand the main (only?) difference between ext2fs and ext3fs is journaling.My questions are;What is journaling? Is it similar to NTFS in how it indexes files, and why would I want journaling? Quote Link to comment Share on other sites More sharing options...
korgg Posted December 12, 2005 Report Share Posted December 12, 2005 Keeping it short, journaling means mainly that every transaction that takes place on your "journalized partition" is is kept into a journal for a period of time... An as far as I know in a journalized enviroment changes to disk do not take place instantly, but after a period of time... Also, depending on the partition type, it may vary the way that data from the disk is accessed...Maybe the most visible difference is when you reboot after a power failure... Having a journal, the maintainace program (fsck let's say ) takes very little time to check the file system, because it knows which disk change took place and which did not.. It reades only the journal ... Not having one, means that fsck has to check all partitions and as you may know it takes a hell of a long time usually ...And I don't think it has any resemblance with the NTFS FS ...Do a google.com/linux for some info... Hope I'm not feeding wrong info about this .. Quote Link to comment Share on other sites More sharing options...
