X-BeenThere: freebsd-fs@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Filesystems List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 08 Sep 2010 16:49:09 -0000 Reading the wiki guides they mention the official way to add swap volumes on ZFS (set org.freebsd:swap=on etc..), So I thought that it should work now, But I just got a panic in 8.1-RELEASE after a heavy memory situation that touched swap for the first time. It is a hassle to add gmirror volumes for swap on full zfs systems, is there any workaround for this, or any news when a fix is coming or if it is coming? The guides also mention to turn checksums=off on the swap volume, I don't understand why, but can this be related to the panics because I had the checksums enabled in my case. If the current code procudes guaranteed panics with zfs swap, I think that every mention of swap on zfs should be removed from the semi-official wiki guides. Thanks.
