Well, "mke2s -i 1048576" will create an inode for every megabyte (1,048,576 byte) of space on the filesystem. However, once you create a filesystem, it's not possible to increase the number of inodes in that filesystem afterwards. Also, symbolic links also take up inodes, as do block and character devices. So in general you want to overallocate inodes somewhat. For example, if you specify "mke2fs -i 524288" then you will be creating twice as many inodes, since you are asking mke2fs to create an inode for every 512k of space. - Ted _______________________________________________ Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
