    Which is best filesystem for a CompactFlash based embedded Linux?


    Title says it all.
    I'm running a Linux from CF disk with ext3 fs.After repeated hangs due to hardware watchdog, sometimes filesystem gets corrupted,and fsck lets it unrecoverable (files dissapeared,permissions denied...etc).Rebuild of CF with a dd command from fresh data is then the only way to go, but this is a critical 24x7 system and that requires manual intervention.So I´d like to know if there is a better suited file system for compact flash working.Thank you!

    I don't think ext3 is best suited for flash-based file system. Check out JFFS2 JFFS2 - Wikipedia, the free encyclopedia or others Flash file system - Wikipedia, the free encyclopedia
