I'm in the process of removing a concatenated vinum volume, consisting of a partition/slice on da0 plus the entire da1. The two drives are 36GB SCSI. I removed the vinum configuration with 'vinum resetconfig' and then just created a new partition etc. on da1 and mounted it. Then I wanted to reclaim the rest of the unused disk space on da0 (about 18GB) with /stand/sysinstall, but got this warning that I haven't seen before. lqqqqqqqqqqqqqqqqqqqqqqqqqqqq Message qqqqqqqqqqqqqqqqqqqqqqqqqqqqqk xWARNING: A geometry of 99565/40/18 for da0 is incorrect.

The amount of sectors in the warning message works out as 71,686,800 which is 4,770 more than what fdisk thinks. I don't get warning message with da1, however. Is this a side-effect of "dangerously dedicated mode"? I'm hesitant to make any changes to the partition table of da0 at this stage. If this is described in a FAQ/How-To/mailing list archive somewhere, apologies and please direct me to the right place... :-) Cheers, -- Juha To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
