| | | | | | | | | | | | | | | | | | | | | robust. With these changes fsck is now able to detect and reliably rebuild corrupted cylinder group maps. The -D option is no longer necessary as it has been replaced by a prompt asking whether the corrupted cylinder group should be rebuilt and doing so when requested. These actions are only offered and taken when running fsck in manual mode. Corrupted cylinder groups found during preen mode cause the fsck to fail. Add the -r option to free up excess unused inodes. Decreasing the number of preallocated inodes reduces the running time of future runs of fsck and frees up space that can allocated to files. The -r option is ignored when running in preen mode.

* This commit adds basic support for the UFS2 filesystem. The UFS2Kirk McKusick2002-06-211-53/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

To try out this change, set the fsck passno to zero in /etc/fstab to cause the filesystem to be mounted without running fsck, then run `fsck_ffs -p -B <filesystem>' after the system has been brought up multiuser to run a background cleanup on <filesystem>.

* Fsck_ffs did not properly range-check the inode 'di_size'Ian Dowse2001-01-311-3/+6
| | | | | | | | | | | | | | | | | | | | | | field, so it was possible for a filesystem marked clean by fsck_ffs to cause kernel crashes later when mounted. This could occur when fsck_ffs was used to repair a badly corrupted filesystem. As pointed out by bde, it is not sufficient to restrict di_size to just the superblock fs_maxfilesize limit. The use of 32-bit logical block numbers (both in fsck and the kernel) induces another file size limit which is usually lower than fs_maxfilesize. Also, the old 4.3BSD filesystem does not have fs_maxfilesize initialised. Following this change, fsck_ffs will enforce exactly the same file size limits as are used by the kernel.
