An rpi2 running -current reported errors during boot like this on the serial console after a graceful reboot: UFS /dev/ufs/rootfs (/) cylinder checksum failed: cg 0, cgp: 0x4c0a5f41 != bp: 0x38b82866 UFS /dev/ufs/rootfs (/) cylinder checksum failed: cg 3, cgp: 0x58e2c1f5 != bp: 0x903c297 UFS /dev/ufs/rootfs (/) cylinder checksum failed: cg 0, cgp: 0x4c0a5f41 != bp: 0x38b82866 /: write failed, filesystem is full cp: /etc/motd: No space left on device . Mounting late filesystems:. Dec 14 10:08:56 www kernel: pid 1394 (cp), uid 0 inumber 53912 on /: filesystem full Root is on the microSD card, /usr /var /tmp and swap are on usb flash. Nevertheless, it reached multi-user and allowed me to ssh in and run df, which reported Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/ufs/rootfs 1473116 479936 875332 35% / devfs 1 1 0 100% /dev /dev/msdosfs/MSDOSBOOT 51140 7588 43552 15% /boot/msdos /dev/da0e 52221244 28697844 19345704 60% /usr /dev/da0d 3044988 517860 2283532 18% /tmp /dev/da0a 2031132 122868 1745776 7% /var Still, any activity that wrote to disk repeated the filesystem full error. This happened with three different kernels, dating Dec 12, 7 and Aug 26. Running fsck -fy once in single user didn't seem to help, although it finished without obvious errors. Running fsck -fy repeatedly in single-user seems to have cleared the error, but it's a surprising development. Thanks for reading, bob prohaska
