--- Comment #2 from midwinter1...@gmail.com --- (In reply to Chao Yu from comment #1) > How to reproduce this, remount to change io_bits option? It's not triggered by remount, the following script manifests it (note that this bug does not occur deterministically, you may execute it repeatedly): ``` #!/bin/bash DISK=bingo.img MOUNT_DIR=/root/mnt dd if=/dev/zero of=$DISK bs=1M count=180 mkfs.f2fs -a 1 -o 9 -t 0 -z 10 -f -q $DISK mkdir -pv $MOUNT_DIR # A little bit long options, I have not reduced it yet. mount $DISK $MOUNT_DIR -o "background_gc=on,disable_roll_forward,no_heap,nouser_xattr,active_logs=2,disable_ext_identify,inline_dentry,noinline_dentry,flush_merge,nobarrier,noextent_cache,noinline_data,checkpoint=disable,usrquota,grpquota,quota,noquota,alloc_mode=reuse,fsync_mode=posix" mkdir -pv $MOUNT_DIR/a new_dir="$MOUNT_DIR/a" for (( i = 0; i < 512; i++ )); do name=`head /dev/urandom | tr -dc A-Za-z0-9 | head -c 1` new_dir="$new_dir/$name" mkdir $new_dir done mv "$MOUNT_DIR/a" "$MOUNT_DIR/b1" mkdir -pv "$MOUNT_DIR/b1/b2/b3/b4/b5" sync for (( i = 0; i < 4096; i++ )); do name=`head /dev/urandom | tr -dc A-Za-z0-9 | head -c 10` mkdir $MOUNT_DIR/b1/b2/b3/b4/b5/$name done umount $MOUNT_DIR ``` Sorry that I didn't provide the script before because it's tedious for me to reduce it. :( -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ Linux-f2fs-devel mailing list Linux-f2fs-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-f2fs-devel
