Hi, I just tried to do an in-place upgrade from RELENG_5 to RELENG_6 on a system that was running an ataraid mirror on a pair of SATA disks. The root file system (256M) mounted fine, but fsck -p fails (unable to find a superblock, from memory) under the new kernel on my /usr partition, which is about 73G (most of the 80G of the disks). Falling back to the RELENG_5 /boot/kernel and fsck finds no problem. Is there a known behaviour change in ataraid behaviour between the two versions? The hardware is Intel P4, ICH6 SATA150, and a pair of Seagate 80G SATA drives. One odd-looking thing that I've just noticed (in RELENG_5, of course) is that fdisk ar0 says that cylinders=9729 heads=255 sectors/track=63, but fdisk ad4 (the first of the "real" SATA disks) says cylinders=155061, heads=16, sectors/track=63. Should these really be so different? Is backup and start again from label/newfs my only option? Cheers, -- Andrew
