However, to reap the benefits of dir_index, you need to run Linux 2.6, or a specially patched 2.4. I believe that if you're hopping between both versions, you need to run fsck -fD on your ext3 volumes. Unfortunately this takes a lot of time to run on my big volume with over a million files--I'd love to do it on-line to save downtime, but I don't believe such a tool to do this safely[1] exists. Matt [1] by safely I meant atomically. If you don't care about this then tar will suffice! Or, better, do a "find -type d", re-make the hierarchy and mv all your files (etc) across. This can be atomic for file handles modulo modulo the big fat race of no opens or creates (etc) are called ;) _______________________________________________ Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
