Hi, Sanity check whether the mirrored vinum root drive is setup correctly. Going to setup two more machines the same way, so wanted to make sure the reference machine was setup correctly. Was surprised to see that the vinum dumpconfig shows the offset for the swap partition to be 265. Remember vaguely that it was supposed to be 281. Do I have a misconfigured machine? The bsdlabel reports the offset to be 281. The vinum.conf used driveoffset of 265s for swap - would think it should have been 281s. The machine works, but have had a couple of unexplained reboots. The mirrored drives are ad4s1 and ad8s1. Thanks for any advice, Richard ------------------------------------------------------- Details: ------------------------------------------------------- ------------------------ vinum.conf:
