.TH FSCK.BOOKMARKFS 1 "Dec 01, 2024" 0.1.0 "BookmarkFS User Manual"
.
.SH NAME
fsck.bookmarkfs - check and repair a BookmarkFS filesystem
.
.SH SYNOPSIS
.B fsck.bookmarkfs
.RI [ options ]
.I pathname
.
.SH DESCRIPTION
The
.B fsck.bookmarkfs
program checks and optionally repairs a BookmarkFS filesystem.
.PP
Unlike fsck for on-disk filesystems (e.g., ext4), this program
does not check for data integrity of the bookmark storage.
Instead, it checks for bookmark names that are not valid as filename
(e.g., contains slash characters).
.PP
See the full user manual for details.
.SS Online mode
In online mode, fsck is performed on a mounted BookmarkFS filesystem.
.PP
The
.I pathname
argument refers to the directory to operate on.
.SS Offline mode
In offline mode, fsck is performed directly on the bookmark storage
via the corresponding backend.
.PP
The
.I pathname
argument is the path to the bookmark storage, equivalent to the
.I src
argument for
.BR mount.bookmarkfs (1).
.PP
Alternatively,
.I pathname
could be a colon-separated string
.RI \[dq] src : dir \[dq],
where
.I dir
refers to the directory to operate on,
relative to the root directory of the subsystem.
.

.SH NOTES
.SS Backends
See the NOTES section in
.BR mount.bookmarkfs (1)
for details.
.SS Handlers
A BookmarkFS fsck handler provides a way to deal with errors found during fsck.
In addition to the default built-in handler, there is also a "tcl" handler,
which allows handling fsck errors with Tcl scripting.
.PP
Like backends, fsck handlers can also be implemented as loadable modules.
See the full user manual for details.
.SS Availability on FreeBSD
Online fsck requires that the FUSE client supports
.BR ioctl (2),
which is currently not available on stable releases of FreeBSD.
See the NOTES section in
.BR bookmarkctl (1)
for details.
.PP
Offline fsck does not have this limitation.
