A preliminary development version of ext4 was included in version 2.6.19[4] of the Linux kernel. On 11 October 2008, the patches that mark ext4 as stable code were merged in the Linux 2.6.28 source code repositories,[5] denoting the end of the development phase and recommending ext4 adoption. Kernel 2.6.28, containing the ext4 filesystem, was finally released on 25 December 2008 http://en.wikipedia.org/wiki/Ext4 CentOS5.5 has the 2.6.18.* kernel so doesn't support ext4 From: Jason Pyeron <jpyeron at pdinc.us> To: 'CentOS mailing list' <centos at centos.org> Cc: Sent: Thursday, December 9, 2010 9:38:20 AM Subject: [CentOS] 5.5 x86_64 live cd In the bang head and repeat mode here.
