Hi there, I have a RAID1 with gmirror between ad6s1 and ad10s1: Name Status Components mirror/mirror_swap COMPLETE ad6s1 ad10s1 If I run bsdlabel on ad6s1 I get the 'partition c ' error: -- # bsdlabel ad6s1 # /dev/ad6s1: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 20964304 0 swap c: 20964320 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 -- but if I do it on the mirror, it shows the *same* info, but no error: # bsdlabel /dev/mirror/mirror_swap # /dev/mirror/mirror_swap: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 20964304 0 swap c: 20964320 0 unused 0 0 # "raw" part, don't edit From fdisk # fdisk -s ad6 /dev/ad6: 484521 cyl 16 hd 63 sec Part Start Size Type Flags 1: 63 20964321 0xa5 0x00 2: 20964825 467426295 0xa5 0x00 # uname -rm 6.0-BETA3 amd64 I can see that it seems ad6s1c is actually 1 sector smaller than the whole slice (20964320 vs 20964321 ). Other than that, the system is working ok. 1) how serious is the problem? 2) Why doesn't it show the same error on the mirror? Is it because the mirror is actually 1 sec smaller than the slices that make the mirror? I tried to fix it via: bsdlabel -R /dev/ad6s1 partition_mirror_swap.txt but I get: # bsdlabel -R /dev/ad6s1 partition_mirror_swap.txt bsdlabel: Geom not found which doesn't make sense as a) I have mirrors running b) geom_mirror is built into the kernel # cat partition_mirror_swap.txt # /dev/mirror/mirror_swap: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 20964304 0 swap 0 0 c: 20964321 0 unused 0 0 # "raw" part, don't edit thanks in advance, Beto
