backwards compatible??backwards compatible??Posted Oct 14, 2008 0:13 UTC (Tue) by qg6te2 (guest, #52587)In reply to: backwards compatible?? by dlang Parent article: Linux Summit will preview new advanced file system (SearchEnterpriseLinux.com)
Ext4 is backwards-compatible in the sense that it can mount Ext3 partitions. Ext3, on the other hand, is not fully forwards-compatible with Ext4. The forwards-incompatability arises when an Ext3 partition is converted to use the extents feature of Ext4.

Note that this is the default when an ext3 partition is mounted as ext4!
