How big is the directory? Sounds like you need the htree patches. These are included in the 2.5 kernel, or they can be applied to the 2.4 tree. Patches against 2.4.21rc8 can be found here: http://thunk.org/tytso/linux/extfs-2.4-update/extfs-update-2.4.21rc8 After you have an htree-enabled kernel, you need to actually enable the htree feature by running the following commands on the unmounted filesystem: tune2fs -O dir_index /dev/hdXXX e2fsck -fD /dev/hdXXXX I strongly suggest that you upgrade your e2fsprogs to at least versoin 1.30 (1.33 is the latest release of e2fsprogs) before trying to use the htree ext2/3 feature. - Ted _______________________________________________ Ext3-users@redhat.com https://www.redhat.com/mailman/listinfo/ext3-users
