Recommendation for ext2 or ext3 with CompactFlash

Started by Unknown December 26, 2007
Hello,

We are developing a Linux based embedded system that will use
CompactFlash.

Should we prefer ext2 or ext3?  How should we think about the trade-
offs?

What is your experience using either in a fielded system?

Thanks.

I tend to use ext2 or even minix filesystems for this purpose. You could also consider loopback-mounting the filesystem on top of fat which will enable customers to update the Software using M$ Operating Systems. Linux _does_ have very a very good Journaling Flash Filesystem (jffs2), but unfortunately the block device emulation of common flash devices like CompactFlash or SD-cards does not allow us to use this filesystem in conjunction with such devices.
