Yes, ZFS does that. But they don't assume you want it always on, so it's off by default. zpool set autoexpand=on tank But in ZFS if you lose more than your redundancy volumes, your whole pool is swiss cheese. Unlike unraid, as you described, where you could lose n+1 of your disks, and only lose some of your files. But even losing 5% of your files is usually considered fatal, so that's why people usually adopt the strategy of never losing more than their redundancy level, and make sure you have backups. _______________________________________________ Discuss mailing list [email protected] http://blu.org/mailman/listinfo/discuss
