Ubuntu 10.04.3 LTS x86_64, I am seeing the following in
EXT4-fs warning (device sda3): ext4_dx_add_entry: Directory index full!
Relevant info from dumpe2fs:
Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery extent flex_bg sparse_super large_file huge_file uninit_bg dir_nlink extra_isize Filesystem flags: signed_directory_hash Free blocks: 165479247 Free inodes: 454382328 Block size: 2048 Inode size: 256
I've already read some other questions, such as ext3_dx_add_entry: Directory index full and rm on a directory with millions of files; those made me think that there must be a directory with a big number of items in it somewhere.
Since it is a rather complex directory organization I have a basic problem: how can I find the directory which is generating those messages?
