| | | | | | | | | | | | | | | | | | | | | | | | | | | states. First its new name will be created causing it to have two names (from possibly different parents). Next, if it has different parents, its value of ".." will be changed from pointing to the old parent to pointing to the new parent. Concurrently, its old name will be removed bringing it back into a consistent state. When fsck encounters an extra name for a directory, it offers to remove the "extraneous hard link"; when it finds that the names have been changed but the update to ".." has not happened, it offers to rewrite ".." to point at the correct parent. Both of these changes were considered unexpected so would cause fsck in preen mode or fsck in background mode to fail with the need to run fsck manually to fix these problems. This update changes these errors to be expected so that in preen mode fsck will simply fix these transitional errors. For now, background fsck will note these errors, but will need additional kernel support to fix them, so will simply ignore them rather than fail. A future update will allow background fsck to fix these problems. Reported by: jeff Notes: svn path=/head/; revision=202107

| | | | | | | | | | | | | | | | | | | | | 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 The -D option is no longer necessary as it has been replaced by a prompt asking whether the corrupted cylinder group should be rebuilt and doing so when requested.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.

By inspecting the code and some old commit log, I believe that the check must be that *fs_sbsize* is larger than sizeof fs. We round up the size to nearest dev_bsize, as the smallest accepted fs_sbsize, personally, I think this can be even changed to equal, because this number is mostly an invariant in file systems. With this check, fsck_ffs(8) will be more picky and has better chance rejecting bad first superblock rather than referring to bad value it supplied, thus gives better chance for it to check the filesystem carefully.

| | | | | | | | | | | | | | | | | | | | | | | | | | initializing the sysctl mibs data before actually using them. The original patchset (which is the actual version that is running on my testboxes) have checked whether all of these sysctls and refuses to do background fsck if we don't have them. Kirk has pointed out that refusing running fsck on old kernels is pointless, as old kernels will recompute the summary at mount time, so I have removed these checks. Unfortunatelly, as the checks will initialize the mib values of those sysctl's, and which are vital for the runtime summary adjustment to work, we can not simply remove the check, which will lead to problem when running background fsck over a dirty volume. Add these checks in a different way: give a warning rather than refusing to work, and complain if the functionality is not available when adjustments are necessary.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | very slow process, especially for large file systems that is just recovered from a crash. Since the summary is already re-sync'ed every 30 second, we will not lag behind too much after a crash. With this consideration in mind, it is more reasonable to transfer the responsibility to background fsck, to reduce the delay after a crash. Add a new sysctl variable, vfs.ffs.compute_summary_at_mount, to control this behavior. When set to nonzero, we will get the "old" behavior, that the summary is computed immediately at mount time. Add five new sysctl variables to adjust ndir, nbfree, nifree, nffree and numclusters respectively. Teach fsck_ffs about these API, however, intentionally not to check the existence, since kernels without these sysctls must have recomputed the summary and hence no adjustments are necessary. This change has eliminated the usual tens of minutes of delay of mounting large dirty volumes. Reviewed by: mckusick MFC After: 1 week Notes: svn path=/head/; revision=142123
