Actually, that's no longer true. Ext3 filesystems can be resized online (in both directions) starting with the 2.6.x kernels. However, it requires the filesystem to have originally been created with the "-O resize_inode" option, which is a pretty big caveat since it requires you to have anticipated the need to resize the filesystem when you originally created it. Note that a lot of filesystems (for example, XFS) can be grown online, but can never be shrunk, so ext3's capabilities don't look that bad by comparison. It's still nowhere near what you can do with ZFS, though. Even when you couple ext3 with LVM it's still a painful multi-step process to resize a volume, and there's a real chance of data loss if you get your math wrong. -- David Brodbeck System Administrator, Linguistics University of Washington _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
