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).

NAME
fsck.reiser4 - the program for checking and repairing reiser4 filesystem. SYNOPSIS
fsck.reiser4 [ options ] FILE DESCRIPTION
fsck.reiser4 is reiser4 filesystem check and repair program. CHECK OPTIONS
--check the default action checks the consistency and reports, but does not repair any corruption that it finds. This option may be used on a read-only file system mount. --fix fixes minor corruptions that do not require rebuilding; sets up correct values of bytes unsupported by kernel in the case of trans- parent compression. --build-sb fixes all severe corruptions in super blocks, rebuilds super blocks from scratch if needed. --build-fs fixes all severe fs corruptions, except super block ones; rebuilds reiser4 filesystem from the scratch if needed. -L, --logfile forces fsck to report any corruption it finds to the specified logfile rather then on stderr. -n, --no-log prevents fsck from reporting any kind of corruption. -a, --auto automatically checks the file system without any questions. -q, --quiet supresses gauges. -r ignored. PLUGIN OPTIONS
--print-profile prints the plugin profile. This is the set of default plugins used for all parts of a filesystem -- format, nodes, files, directo- ries, hashes, etc. If --override is specified, then prints modified plugins. -l, --print-plugins prints all plugins libreiser4 know about. -o, --override TYPE=PLUGIN, ... overrides the default plugin of the type "TYPE" by the plugin "PLUGIN" in the plugin profile. COMMON OPTIONS
-V, --version prints program version -?, -h, --help prints program help -q, --quiet suppress messages. -y, --yes assumes an answer 'yes' to all questions. -f, --force forces fsck to use whole disk, not block device or mounted partition. -p, --preen automatically repair minor corruptions on the filesystem. -c, --cache N tunes number of nodes in the libreiser4 tree buffer cache REPORTING BUGS
