What is ext3?
ext3 is a journaling file system. Being the third generation of the Extended Filesystem (full name: Third extended file system), it is the successor to ext2, to which it is backward compatible, and predecessor to ext4, to which it is party forward-compatible. It was first introduced in November 2001.
It features a maximum file size of 16 GiB..2 TiB, and a maximum volume size of 2..16 TiB. Next to the size improvements, it also brings speed improvements over ext2 (from which it can directly upgrade without data loss).
