I'm using the standard "RAID-array-as-PV" setup, and planning to grow the filesystem as needs demand. I'd like to use a filesystem that supports online grow and online shrink. XFS, JFS, and Reiser3 all support unlimited online grow but no shrink at all. Looks like Ext3 supports online grow, but only up to +16 GB, which makes it useless on modern disks, much less arrays of modern disks.... Looks like offline grow & shrink are unlimited, which is good. Lots of old (unmaintained?) tools and kernel patches here, but lots of recent activity too. What's the current status? -- Sebastian Kuzminsky
