Re: [zfs-discuss] Solaris 10u9 with zpool version 22, but no DEDUP (version 21 reserved)
If not, will any possible problems be avoided if I remove (transfer data away from) any filesystems with dedup=on ? I would think re-copying data from a deduped dataset to a non-deduped dataset will fix it, yes. But then, who knows, perhaps Oracle will fix dedup and make it usable one day...

Dedup changes large I/Os into small I/Os. If you expect dedup to change large I/Os into no I/Os, then you will be unhappy. Thus, the best solution for dedup is one which can handle large amounts of small I/Os. -- richard ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

That Reserved is telling, as that's when de-dupe was integrated: http://hub.opensolaris.org/bin/view/Community+Group+zfs/21 I guess a bit more work needs to be done on it before back porting to Solaris-proper occurs. Some of the stuff in ZFSv20 also has links to de-dupe according to its Hub page: I'm guessing ZLE is used to a certain extent in de-dupe. I take it that ZLE is a form of run-length encoding. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
