Re: [zfs-discuss] Bp rewrite
As someone who has zero insider information and feels that there isn't much push at oracle to develop or release new zfs features, I have to assume it's not coming. The only way I see it becoming a reality is if someone in the illumos community decides to do the work required to put it in.

You obviously missed the thread we had recently about the new ZFS features that Solaris 11 and 11.1 have. ZFS is very much in active feature, bugfix and performance improvement at Oracle for current and future versions of Solaris and the ZFS Storage Appliance. BP rewrite is actually very complex to do correctly and safely - it it wasn't I'm sure it would have been done by now by multiple people! -- Darren J Moffat ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

As for BP rewrite, Darren already noted, it is in a whole special class of hard to do. As for the community involvement: we welcome everybody at Illumos. It's of course impossible to do predictions of future feature progress, but we have our own stuff in the works and unlike the opensolaris.org website (don't know about the mailing lists), we won't plan on winding down by the end of next month. If the fine people at Oracle keep a good pace, it's possible you'll see a steady stream of improvements from them as well (though I personally suspect that they'll hand you the improvements in one hand and a hefty invoice in the other).

[zfs-discuss] BP rewrite? (Was Re: spreading data after adding devices to pool)
Anyone knows where in the pipeline BP rewrite is, or how long this pipeline is? You could move the data elsewhere using zfs send and recv, destroy the original datasets and then recreate them. This would stripe the data across the vdevs. Of course, when BP-rewrite becomes available it should be possible to simply redistribute blocks amongst the various vdevs without having to go through destroying/creating.

I started on 4 drives then added 4 and have now added another 4, bringing the total up to 12 drives on 3 raidzs in 1 pool. I was just wondering if there was any advantage or disadvantage to spreading the data across the 3 raidz, as two are currently full and one is completely empty. If it would improve performance to spread the data, is there any easy way to do it? -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss -- Matt Urbanowski Graduate Student 5-51 Medical Sciences Building Dept.

+1 I badly need this. On 09/07/2010, at 19.40, Roy Sigurd Karlsbakk wrote: Anyone knows where in the pipeline BP rewrite is, or how long this pipeline is?
