Normally you +only need this option if mount reports "read_super_block: can't find +a reiserfs file system" and you are sure that a Reiserfs file system is +there. But remember that if you have used some partition editor program and +now you cannot find a filesystem, probably something has gone wrong while +repartitioning and the start of the partition has been changed. If so, +instead of rebuilding the super block on a wrong place you should find the +correct start of the partition first. +.TP +.B --check +This default action checks filesystem consistency and reports, but +does not repair any corruption that it finds. This option may be +used on a read-only file system mount. +.TP +.B --fix-fixable +This option recovers certain kinds of corruption that do not require +rebuilding the entire file system tree (\fB--rebuild-tree\fR). Normally +you only need this option if the \fB--check\fR option reports +"corruption that can be fixed with \fB--fix-fixable\fR". This includes: +zeroing invalid data-block pointers, correcting st_size and st_blocks +for directories, and deleting invalid directory entries. +.TP +.B --rebuild-tree +This option rebuilds the entire filesystem tree using leaf nodes +found on the device. Normally you only need this option if the +\fBreiserfsck \-\-check\fR reports "Running with \fB\-\-rebuild-tree\fR +is required". You are strongly encouraged to make a backup copy +of the whole partition before attempting the \fB--rebuild-tree\fR +option. Once \fBreiserfsck \-\-rebuild-tree\fR is started it must +finish its work (and you should not interrupt it), otherwise the +filesystem will be left in the unmountable state to avoid subsequent +data corruptions. +.TP +.B --clean-attributes +This option cleans reserved fields of Stat-Data items. There were days when +there were no extended attributes in reiserfs. When they were implemented old +partitions needed to be cleaned first -- reiserfs code in the kernel did not +care about not used fields in its strutures. Thus if you have used one of the +old (pre-attrbutes) kernels with a ReiserFS filesystem and you want to use +extented attribues there, you should clean the filesystem first. +.TP +.B \fB--journal \fIdevice \fR, \fB-j \fIdevice \fR +This option supplies the device name of the current file system journal. +This option is required when the journal resides on a separate device +from the main data device (although it can be avoided with the expert +option \fB--no-journal-available\fR). +.TP +.\" .B --interactive, -i +.\" This makes \fBreiserfsck\fR to stop after each pass completed. +.\" .TP +.B --adjust-size, -z +This option causes \fBreiserfsck\fR to correct file sizes that +are larger than the offset of the last discovered byte. This +implies that holes at the end of a file will be removed. File +sizes that are smaller than the offset of the last discovered +byte are corrected by \fB--fix-fixable\fR. +.TP +\fB--badblocks \fIfile\fR, \fB-B \fI file\fR +This option sets the badblock list to be the list of blocks specified in +the given `file`. The filesystem badblock list is cleared before the new +list is added. It can be used with \fB--fix-fixable\fR to fix the list of +badblocks (see \fBdebugreiserfs \-B\fR). If the device has bad blocks, every +time it must be given with the \fB--rebuild-tree\fR option. +.TP +\fB--logfile \fIfile\fR, \fB-l \fI file\fR +This option causes \fBreiserfsck\fR to report any corruption it finds +to the specified log file rather than to stderr. +.TP +.B --nolog, -n +This option prevents \fBreiserfsck\fR from reporting any kinds of corruption. +.TP +.B --quiet, -q +This option prevents \fBreiserfsck\fR from reporting its rate of progress. +.TP +.B --yes, -y +This option inhibits \fBreiserfsck\fR from asking you for confirmation after +telling you what it is going to do. It will assuem you confirm. For safety, +it does not work with the \fB--rebuild-tree\fR option. +.TP +\fB-a\fR, \fB-p\fR +These options are usually passed by fsck \-A during the automatic checking +of those partitions listed in /etc/fstab. These options cause \fBreiserfsck\fR +to print some information about the specified filesystem, to check if error +flags in the superblock are set and to do some light-weight checks. If these +checks reveal a corruption or the flag indicating a (possibly fixable) +corruption is found set in the superblock, then \fBreiserfsck\fR switches +to the fix-fixable mode. If the flag indicating a fatal corruption is found +set in the superblock, then \fBreiserfsck\fR finishes with an error. +.TP +.B --force, -f +Force checking even if the file system seems clean. +.TP +.B -V +This option prints the reiserfsprogs version and then exit. +.TP +.B -r +This option does nothing at all; it is provided only for +backwards compatibility. +.SH EXPERT OPTIONS +DO NOT USE THESE OPTIONS UNLESS YOU KNOW WHAT YOU ARE DOING. +WE ARE NOT RESPONSIBLE IF YOU LOSE DATA AS A RESULT OF THESE +OPTIONS. +.TP +.B \fB\--no-journal-available\fR +This option allows \fBreiserfsck\fR to proceed when the journal device is +not available. This option has no effect when the journal is located on +the main data device. NOTE: after this operation you must use \fBreiserfstune\fR +to specify a new journal device. +.TP +.B --scan-whole-partition, -S +This option causes \fB--rebuild-tree\fR to scan the whole partition but not only +the used space on the partition. +.SH AN EXAMPLE OF USING reiserfsck +1. You think something may be wrong with a reiserfs partition on /dev/hda1 +or you would just like to perform a periodic disk check. + +2. Run \fBreiserfsck \-\-check \-\-logfile check.log /dev/hda1\fR. If \fBreiserfsck +\-\-check\fR exits with status 0 it means no errors were discovered. + +3. If \fBreiserfsck \-\-check\fR exits with status 1 (and reports about fixable +corruptions) it means that you should run \fBreiserfsck \-\-fix-fixable \-\-logfile +fixable.log /dev/hda1\fR. + +4. If \fBreiserfsck \-\-check\fR exits with status 2 (and reports about fatal +corruptions) it means that you need to run \fBreiserfsck \-\-rebuild\-tree\fR. +If \fBreiserfsck \-\-check\fR fails in some way you should also run \fBreiserfsck +\-\-rebuild-tree\fR, but we also encourage you to submit this as a bug report. + +5. Before running \fBreiserfsck \-\-rebuild-tree\fR, please make a backup of +the whole partition before proceeding. Then run \fBreiserfsck \-\-rebuild-tree +\-\-logfile rebuild.log /dev/hda1\fR. + +6. If the \fBreiserfsck \-\-rebuild-tree\fR step fails or does not recover what +you expected, please submit this as a bug report. Try to provide as much +information as possible including your platform and Linux kernel version. We +will try to help solve the problem. +.SH EXIT CODES +\fBreiserfsck\fR uses the following exit codes: +.br +\ \fI0\fR \-\ No errors. +.br +\ \fI1\fR \-\ File system errors corrected. +.br +\ \fI2\fR \-\ Reboot is needed. +.br +\ \fI4\fR \-\ File system fatal errors left uncorrected, +.br +\ \fBreiserfsck \-\-rebuild-tree\fR needs to be launched. +.br +\ \fI6\fR \-\ File system fixable errors left uncorrected, +.br +\ \fBreiserfsck \-\-fix-fixable\fR needs to be launched. +.br +\ \fI8\fR \-\ Operational error. +.br +\ \fI16\fR \-\ Usage or syntax error. +.br +.SH AUTHOR +This version of \fBreiserfsck\fR has been written by Vitaly Fertman <vitaly@namesys.com>. +.SH BUGS +Please report bugs to the ReiserFS developers <reiserfs-devel@vger.kernel.org>, providing +as much information as possible--your hardware, kernel, patches, settings, all printed +messages, the logfile; check the syslog file for any related information. +.SH TODO +Faster recovering, signal handling. +.SH SEE ALSO +.BR mkreiserfs (8), +.BR reiserfstune (8) +.BR resize_reiserfs (8), +.BR debugreiserfs (8), |
