Hi, There seems to be some bug in the kernel. On another partition reformatted on week ago, I had again the following error:
NILFS error (device sda3): nilfs_check_page: bad entry in directory #28261: unaligned directory entry - offset=4096, inode=1647255843, rec_len=29537, name_len=104 NILFS error (device sda3): nilfs_check_page: bad entry in directory #28261: unaligned directory entry -

This time, I paid attention to run the cleaner always when there was more than 5 gigabytes (20%) of freee space on the volume.
