We generally only test up to 10M files in a single directory. If you had a perfect hash distribution you might be able to get to 25M files in the directory. I suspect if you run "e2fsck -fD" it might help you (its job is to pack the directories), but I suspect it has never been run on such a large directory and might conceivably use too much RAM to run on the system. > On MDS we get this in the kernel log: > [692361.061558] LDISKFS-fs warning (device sdb2): ldiskfs_dx_add_entry: > Directory index full! This is one of the reasons we are moving to ZFS for the back-end storage.
