ZFS is not "broken." It is, however, a weak spot, that resilver is very inefficient. For example: On my server, which is made up of 10krpm SATA drives, 1TB each... My drives can each sustain 1Gbit/sec sequential read/write. This means, if I needed to resilver the entire drive (in a mirror) sequentially, it would take ... 8,000 sec = 133 minutes. About 2 hours. In reality, I have ZFS mirrors, and disks are around 70% full, and resilver takes 12-14 hours. So although resilver is "broken" by some standards, it is bounded, and you can limit it to something which is survivable, by using mirrors instead of raidz. For most people, even using 5-disk, or 7-disk raidzN will still be fine. But you start getting unsustainable if you get up to 21-disk radiz3 for example. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
