I just made world on -CURRENT (cvsup a few hours ago), booted using a new GENERIC kernel and ran mergemaster. Before I installed world, I mounted the root partition for my more stable development environment (4.6-RELEASE) to copy my firewall rules over. In summary: # mount /dev/ad1s1a /mnt # mount -ur /mnt # Oops...wanted r/o # cp /mnt/etc/rc.firewall /etc/rc.firewall # umount /mnt # cd /usr/src && make installworld I rebooted cleanly a little while later. The next time I booted into 4.6-RELEASE, fsck was very unhappy. # fsck /dev/ad1s1a ** /dev/ad1s1a BAD SUPER BLOCK: VALUES IN SUPER BLOCK DISAGREE WITH THOSE IN FIRST ALTERNATE /dev/ad1s1a: INCOMPLETE LABEL: type 4.2BSD fsize 0, frag 0, cpg 0, size 524288 # fsdb /dev/ad1s1a ** /dev/ad1s1a BAD SUPER BLOCK: VALUES IN SUPER BLOCK DISAGREE WITH THOSE IN FIRST ALTERNATE /dev/ad1s1a: INCOMPLETE LABEL: type 4.2BSD fsize 0, frag 0, cpg 0, size 524288 fsdb: cannot set up file system `/dev/ad1s1a' # disklabel /dev/ad1s1 # /dev/ad1s1: [snip] 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 524288 0 4.2BSD 0 0 0 # (Cyl. 0 - 32*) b: 524288 524288 swap # (Cyl. 32*- 65*) c: 35230482 0 unused 0 0 # (Cyl. 0 - 2192*) e: 524288 1048576 4.2BSD 0 0 0 # (Cyl. 65*- 97*) f: 524288 1572864 4.2BSD 0 0 0 # (Cyl. 97*- 130*) g: 21504000 2097152 4.2BSD 0 0 0 # (Cyl. 130*- 1469*) h: 11629330 23601152 4.2BSD 0 0 0 # (Cyl. 1469*- 2192*) I can still mount the partition and it seems to be fine. Did this have something to do with the two seconds that the partition was mounted r/w? I suspect that relabeling the slice will fix the problem, but what went wrong?
