Traditional Linux filesystems

- [Instructor] Let's take a look…at traditional Linux file systems.…It all started with the extended file system…which was designed for Linux,…as compared to file systems at that time…that were developed for Minix and Unix.…It was quickly followed by ext2,…which improved on the original…by adding inodes and reducing fragmentation.…It also increased the limits on files sizes…and the size of the file system as a whole.…

It was the first of the Linux file systems to use…Virtual File System.…It's also of use today when working with flash storage…like SD cards and USB flash drives…that have a life dependent upon…how many times you write to the memory.…So if you're going to be using USB flash drive…as a portable means of moving files around…between your Linux servers, you might want to use ext2.…

Ext3 is backwards compatible with ext2.…And that goes both directions.…So if you have an ext2 file system,…you can mount it with the ext3 driver…and get the benefits of that,…or, if you have an ext3 file system,…and you need to mount it as an ext2 for some reason,…
