I have tried many ideas of padding these partitions so I don't get this message, but to noavail. I'm willing to try more, the machine isn't live (yet) so it can sit here while it gets figured out. :) Back at 9.2-PRERELEASE #0 r255456 I used the same procedure for setting up a gmirror, and this worked fine with no corruption. Here's the partition table: > gpart show => 34 976773101 ada0 GPT (465G) 34 46245840 1 freebsd-swap (22G) 46245874 930523232 2 freebsd-ufs (443G) 976769106 4029 - free - (2M) => 34 976773101 ada1 GPT (465G) 34 46245840 1 freebsd-swap (22G) 46245874 930523232 2 freebsd-ufs (443G) 976769106 4029 - free - (2M) => 34 46245772 mirror/swap0 GPT (22G) 34 46245772 1 freebsd-swap (22G) => 34 930523164 mirror/rw0 GPT (443G) 34 926941184 1 freebsd-ufs (442G) 926941218 3581980 - free - (1.7G) I've since upgraded this machine to the exact same 9.3 revision and it still works fine, no corruption. Am I missing something or did something change in between these two revisions that makes it difficult or different to set up? Thanks in advance for any insight you all can provide. -- Dave Hayes - Consultant - Altadena CA, USA - dave@jetcafe.org >>>> *The opinions expressed above are entirely my own* <<<< Enjoyment is not a goal, it is a feeling that accompanies important ongoing activity
