Kernel Log: What's coming in 2.6.30 - Storage: RAID improvements, optimised CFQ
Scheduler, SAS drivers
,----[ Quote ]
| The next kernel version is to provide all that's necessary to convert, for
| example, a RAID 5 into a RAID 6 and vice versa. There are changes to the
| block layer designed to speed up the system, and new and improved drivers
| will offer better SAS support.
|
| With the fifth release candidate of Linux 2.6.30 out a few days ago, the
| development of the next kernel version in the main development line continues
| to progress. As indicated by Linus Torvalds in his release email, the changes
| are slowly decreasing in number and size, which is what usually happens at
| this development stage.

ZFS, Btrfs and Oracle
,----[ Quote ]
| Most of you may already be aware of Oracle’s acquisition of Sun Microsystems.
| If not, here is an article stating just that from Sun’s website. I read the
| news as soon as it was published on the net along with the reactions of Sun
| users for Sun products. What will be the future of mySQL or OpenOffice?

ext4: The Fourth Extended Filesystem
,----[ Quote ]
| The ext4 file system is to be the successor to the ext3 journaled file system
| and will be available as an optional file system in the next release of
| Ubuntu, Ubuntu 9.04.
|
| The ext4 file system is now, as of December 25, 2008, released as stable and
| can be used as the dominant file system without fear of data lose…well, to be
| more clear I mean no more fear than any other “stable” file system.

Initial ext3 vs ext4 Results
,----[ Quote ]
| We’ve started to do some internal benchmarking of ext3 vs ext4 at
| myYearbook.com to see if what we’ve seen and heard about ext4 was really
| true. While the following benchmark is not in-depth, it does represent our
| initial findings, which match our anecdotal findings. If all of these
| findings hold true, we expect them to have a large impact on our PostgreSQL
| OLTP workload where machines are IO bound.
