I posted this on the questions list but didn't get a lot of traction. I've 
created GEOM mirrored file systems on two slices of my system's drives and 
everything seems to be working, but I get the warning s 

WARNING: Expected rawoffset 0, found 63 
WARNING: Expected rawoffset 0, found 50332464 

when the mirrors are being created. These correspond to the offsets for these 
slices in the partition table: 

# fdisk -p ad4 
# /dev/ad4 
g c484521 h16 s63 
p 1 0xa5 63 50332401 
a 1 
p 2 0xa5 50332464 16778160 
p 3 0xa5 67110624 421285536 

Partition three is not mirror, just partitions 1 and 2. I use the following 
command to create the slice 1 mirror: 

gmirror label -v -n -b round-robin <mirror-name> <drive-name>s1 

and a similar one for slice 2. Additional drives are added to this mirror after 
the data has been copied to the mirrored file systems. 

The disks are setup with the required labels, including making sure the c 
partition is reduced in size by one sector. E.g.: 

# bsdlabel ad4s1 
# /dev/ad4s1: 
8 partitions: 
# size offset fstype [fsize bsize bps/cpg] 
a: 10485760 16 4.2BSD 2048 16384 28528 
c: 50332400 0 unused 0 0 # "raw" part, don't edit 
d: 8388608 10485776 4.2BSD 2048 16384 28528 
e: 31457280 18874384 4.2BSD 2048 16384 28528 
bsdlabel: partition c doesn't cover the whole unit! 
bsdlabel: An incorrect partition c may cause problems for standard system 
utilities 

# bsdlabel ad4s2 
# /dev/ad4s2: 
8 partitions: 
# size offset fstype [fsize bsize bps/cpg] 
b: 16778143 16 swap 
c: 16778159 0 unused 0 0 # "raw" part, don't edit 
bsdlabel: partition c doesn't cover the whole unit! 
bsdlabel: An incorrect partition c may cause problems for standard system 
utilities 

So as far as I can tell I have everything configured the way it should be and 
everything appears to be working fine, but these warnings worry me. Should I be 
worried?
