Hi, this is true, but it might still be possible to use zfs in a distributed setup, as you can build pools from plain files that may be located anywhere on a network. Automatic status notification would require some custom scripting and it is obviously not recommended by sun ;-) The other dra

Hi Matt, you can use zpool replace pond ad4 after removing your old disk. The problem is, if something goes wrong during the replace, you might lose data, because you have to remove the redundant disk first. Hope this helps, ralf Am 25.04.2008 um 16:42 schrieb [EMAIL PROTECTED]: > [zfs-discuss]

Hi Matt, if you can remember the status information and are the only administrator, you can just doa zpool clear and re-scrub your pool regularly. zpool clear does no more or less than resetting the status and the counters. (A reboot or export does the same thing, at least no Mac OS X.) The p

I've just tried to bfu my system from b87 (which was in turn bfu'ed from OS DP 2, so has a ZFS root as installed by DP 2), and b88 is unbootable. I retrieved the non-debug b88 bfu archives from the ON download page, so am not using a local build. I'm relatively new to debugging boot problems o

No :-) The slightly more longer answer is that I don't think ZFS is what you're looking for, I believe there are other projects better suited (although I don't recall the names off the top of my head). For starters, ZFS only offers at best dual parity raid, so if more than two computers went o
