Operating Systems Solaris Deep checking Solaris ufs filesystem Post 302992986 by jlliagre on Saturday 4th of March 2017 11:15:43 AM

Fsck was designed to check the file system integrity and to repair it when possible. There is no way with fsck to repair the files themselves. Even if all of their blocks are readable, that doesn't mean they are not (silently) corrupted.

That's one of the reasons why UFS is essentially obsolete and replaced by ZFS under Solaris.

With ZFS, you can use "scrub" to check and repair everything, including file contents when there is redundancy (ditto blocks, raidz or mirror).

repair_packages is used by Disk Utility to verify or repair permissions on installed packages. ARGUMENTS
--volume Perform all operations on the specified volume or home directory. The root volume '/' will be used if unspecified. --list-standard-pkgs Output the list of package-id strings corresponding to receipts in the installer's receipt database that will be verified or repaired by the --standard-pkgs flag. --verify Verify the specified package(s). --repair Repair the specified package(s). --pkg package-id Add the specified package to the list of packages to verify or repair. --standard-pkgs Add the standard packages to the list of packages to verify or repair. Use --list-standard-pkgs to view this list. --output-format # Use a special output format selected by #. Different output formats may be optimized for human or machine readability. The default output-format is '0', and is a verbose, human-readable format. NOTES
repair_packages only runs on 10.6 or later systems. To verify or repair permissions on earlier systems, reboot with a Tiger or Leopard system disk and verify or repair permissions with the repair_packages version on that disk. SEE ALSO
