My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

* The purpose of this change to the FFS layout policy is to reduce theKirk McKusick2013-03-221-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | running time for a full fsck. It also reduces the random access time for large files and speeds the traversal time for directory tree walks. The key idea is to reserve a small area in each cylinder group immediately following the inode blocks for the use of metadata, specifically indirect blocks and directory contents. The new policy is to preferentially place metadata in the metadata area and everything else in the blocks that follow the metadata area. The size of this area can be set when creating a filesystem using newfs(8) or changed in an existing filesystem using tunefs(8). Both utilities use the `-k held-for-metadata-blocks' option to specify the amount of space to be held for metadata blocks in each cylinder group. By default, newfs(8) sets this area to half of minfree (typically 4% of the data area). This work was inspired by a paper presented at Usenix's FAST '13: www.usenix.org/conference/fast13/ffsck-fast-file-system-checker Details of this implementation appears in the April 2013 of ;login: www.usenix.org/publications/login/april-2013-volume-38-number-2.

* This commit adds basic support for the UFS2 filesystem. The UFS2Kirk McKusick2002-06-211-24/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | filesystem expands the inode to 256 bytes to make space for 64-bit block pointers. It also adds a file-creation time field, an ability to use jumbo blocks per inode to allow extent like pointer density, and space for extended attributes (up to twice the filesystem block size worth of attributes, e.g., on a 16K filesystem, there is space for 32K of attributes). UFS2 fully supports and runs existing UFS1 filesystems. New filesystems built using newfs can be built in either UFS1 or UFS2 format using the -O option. In this commit UFS1 is the default format, so if you want to build UFS2 format filesystems, you must specify -O 2. This default will be changed to UFS2 when UFS2 proves itself to be stable. In this commit the boot code for reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c) as there is insufficient space in the boot block. Once the size of the boot block is increased, this code can be defined. Things to note: the definition of SBSIZE has changed to SBLOCKSIZE. The header file <ufs/ufs/dinode.h> must be included before <ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and ufs_lbn_t. Still TODO: Verify that the first level bootstraps work for all the architectures. Convert the utility ffsinfo to understand UFS2 and test growfs. Add support for the extended attribute storage. Update soft updates to ensure integrity of extended attribute storage. Switch the current extended attribute interfaces to use the extended attribute storage. Add the extent like functionality (framework is there, but is currently never used). Sponsored by: DARPA & NAI Labs.

You can use dumpfs, but that's not obvious which settings are tuneable, and is far from clear to the non-guru (it's like using a hexdump of a tar archive to get a table-of-contents). There is also an undocumented option in the man page that can be dangerous. Suppose your disk driver decides to scramble all writes while you tell tunefs to update all backup superblocks.
