When I first create /var I took all the defaults. I have since decided that, since it will hold a cyrus mail spool (each message is a file) I should use something with more inodes. I created a new (var2) partition and formatted it with # mkfs.ext3 -T news /dev/mapper/turtle-var2_crypt # news has inode_ratio = 4096 Then I mounted and rsync'd from my existing /var. Afterwords, I get a report that seems to indicate I've used almost no inodes. It also shows more inodes than blocks; is there any way one could need more than one inode/block? # dumpe2fs -h /dev/mapper/turtle-var2_crypt dumpe2fs 1.41.3 (12-Oct-2008) Filesystem volume name: <none> Last mounted on: <not available> Filesystem UUID: 823219cf-30dc-42f9-ac96-1112bc7fe070 Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery sparse_super large_file Filesystem flags: signed_directory_hash Default mount options: (none) Filesystem state: clean Errors behavior: Continue Filesystem OS type: Linux Inode count: 6291456 Block count: 6291199 Reserved block count: 314559 Free blocks: 5853517 Free inodes: 6291445 First block: 0 Block size: 4096 Fragment size: 4096 Reserved GDT blocks: 1022 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 32768 Inode blocks per group: 2048 Filesystem created: Tue May 5 11:10:32 2009 Last mount time: Tue May 5 11:15:34 2009 Last write time: Tue May 5 11:15:34 2009 Mount count: 1 Maximum mount count: 23 Last checked: Tue May 5 11:10:32 2009 Check interval: 15552000 (6 months) Next check after: Sun Nov 1 10:10:32 2009 Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group root) First inode: 11 Inode size: 256 Required extra isize: 28 Desired extra isize: 28 Journal inode: 8 Default directory hash: half_md4 Directory Hash Seed: 95194688-7a78-4087-b013-1aec3e7a8436 Journal backup: inode blocks Journal size: 128M As I read this, 6291445 of 6291456 inodes are free, so 11 are in use. The comparable calculation on the origin file system shows about 8,500 inodes in use. I'm on a 2.6.29 kernel, building file systems on top of encrypted partitions, which in turn are on LVM logical volumes. e2fsprogs 1.41.3-1 on Debian Lenny, amd64 architecture, Xeon chips. Can anyone explain what's going on? Is -h not giving me the complete inode story?
