.SH "NAME"
fsck.btrfs \- do nothing, successfully
.SH "SYNOPSIS"
.sp
\fBfsck\&.btrfs\fR [\-aApy] [\fI<device>\fR\&...]
.SH "DESCRIPTION"
.sp
\fBfsck\&.btrfs\fR is a type of utility that should exist for any filesystem and is called during system setup when the corresponding \fB/etc/fstab\fR entries contain non\-zero value for \fBfs_passno\fR, see \fBfstab\fR(5) for more\&.
.sp
Traditional filesystems need to run their respective fsck utility in case the filesystem was not unmounted cleanly and the log needs to be replayed before mount\&. This is not needed for BTRFS\&. You should set fs_passno to 0\&.
.sp
If you wish to check the consistency of a BTRFS filesystem or repair a damaged filesystem, see \fBbtrfs\-check\fR(8)\&. By default filesystem consistency is checked, the repair mode is enabled via the \fI\-\-repair\fR option (use with care!)\&.
.SH "OPTIONS"
.sp
The options are all the same and detect if \fBfsck\&.btrfs\fR is executed in non\-interactive mode and exits with success, otherwise prints a message about btrfs check\&.
.SH "EXIT STATUS"
.sp
There are two possible exit code returned:
.PP
0
.RS 4
No error
.RE
.PP
8
.RS 4
Operational error, eg\&. device does not exist
.RE
