Debian Lenny and Ext4 Conversion
Debian 5.0 is getting stable. Today we upgraded one of our core servers to Debian Lenny. It worked like a charm. We then used a GRML live-CD in order to convert three heavy-duty partitions from XFS to Ext3 and finally to Ext4 with a shiny 2.6.28.2 kernel on top. The system runs and did not complain once during the procedure.
In order not to spread rumours, XFS does a fine job and we use it, too. It's just that we are testing Ext4 for almost a year now, and we'd like to report that the new file system handles a lot of different work loads, disk sizes and tests very well. It seems to be a perfect successor for the reliable Ext3 file system. You can even convert Ext3 partitions to Ext4 very easy. The recommendation is to populate the Ext4 file system from scratch since formatting enables some features that are not available when doing a conversion.
So if you want to convert file systems or do the next big upgrade as soon as Debian 5.0 is out, let us know. We can help.
