Thanks for your detail explanation. I briefly ran that test case and it worked fine. However unlikely I excepted that it shouldn't work without patch, even without patch I could get correct result. Is it possible to work without patch even though i_blockes is not being preserved? Thanks, Joonwoo p.s. here is my test scripts to run this test with nandsim. I'm running linux-2.6.30 with aufs 2-standalone.tree-30-20090803 please note as first branch of aufs I'm using *read-only* ubifs partition but I think it shouldn't be matter. mkubifs.sh -- #!/bin/sh ubidetach -m 0 /dev/ubi_ctrl 2> /dev/null modprobe ubifs modprobe nandsim first_id_byte=0x20 second_id_byte=0xa2 third_id_byte=0x00 fourth_id_byte=0x15 # 64MiB, 2048 bytes page; ubiformat /dev/mtd0 -s 512 ubiattach /dev/ubi_ctrl -m 0 ubimkvol /dev/ubi0 -s 30000KiB -N slot1 ubimkvol /dev/ubi0 -m -N commonrw -- mountubifs.sh -- #!/bin/sh umount /mnt /realroot/rw /realroot/ro 2> /dev/null mkdir -p /realroot/ro /realroot/rw /mnt mount -t ubifs -o ro ubi0:slot1 /realroot/ro mount -t ubifs -o rw ubi0:commonrw /realroot/rw mount -t aufs -o dirs=/realroot/ro=ro:/realroot/rw=rw,udba=inotify none /mnt -- runtest.sh -- mkdir -p /realroot/rw/directory touch /realroot/rw/file mknod c 4 64 /realroot/rw/ttyS0 mkfifo /realroot/rw/fifo ln -sf /realroot/rw/file /realroot/rw/symlink while [ 1 ]; do touch -m -a /realroot/rw/* stat /realroot/rw/* | egrep 'Access|Modify|Change' | md5sum stat /mnt/* | egrep 'Access|Modify|Change' | md5sum sleep 1; done -- ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
