.SH "NAME"
btrfs-inspect-internal \- resolve different btrfs items for debug purpose
.SH "SYNOPSIS"
.sp
\fBbtrfs inspect\-internal\fR \fI<subcommand>\fR \fI<args>\fR
.SH "DESCRIPTION"
.sp
\fBbtrfs inspect\-internal\fR is used to resolve different items for debug purpose\&.
.SH "SUBCOMMAND"
.PP
\fBinode\-resolve\fR [\-v] \fI<inode>\fR \fI<path>\fR
.RS 4
Resolves an
\fI<inode>\fR
in subvolume
\fI<path>\fR
to all filesystem paths\&.
.sp
\fBOptions\fR
.PP
\-v
.RS 4
verbose mode\&. print count of returned paths and ioctl() return value
.RE
.RE
.PP
\fBlogical\-resolve\fR [\-Pv] [\-s \fI<bufsize>\fR] \fI<logical>\fR \fI<path>\fR
.RS 4
Resolves a
\fI<logical>\fR
address in the filesystem mounted at
\fI<path>\fR
to all inodes\&.
.sp
By default, each inode is then resolved to a file system path (similar to the inode\-resolve subcommand)\&.
.sp
\fBOptions\fR
.PP
\-P
.RS 4
skip the path resolving and print the inodes instead
.RE
.PP
\-v
.RS 4
verbose mode\&. print count of returned paths and all ioctl() return values
.RE
.PP
\-s \fI<bufsize>\fR
.RS 4
set inode container\(cqs size\&.
.sp
This is used to increase inode container\(cqs size in case it is not enough to read all the resolved results\&. The max value one can set is 64k\&.
.RE
.RE
.PP
\fBsubvolid\-resolve\fR \fI<subvolid>\fR \fI<path>\fR
.RS 4
Get file system paths for the given subvolume ID\&.
.RE
.PP
\fBrootid\fR \fI<path>\fR
.RS 4
For a given file or directory, return the containing tree root id\&. For a subvolume return it\(cqs own tree id\&.
.sp
The result is undefined for the so\-called empty subvolumes (identified by inode number 2)\&.
.RE
.SH "EXIT STATUS"
.sp
\fBbtrfs inspect\-internal\fR returns a zero exit status if it succeeds\&. Non zero is returned in case of failure\&.
.SH "AVAILABILITY"
.sp
\fBbtrfs\fR is part of btrfs\-progs\&. Please refer to the btrfs wiki \m[blue]\fBhttp://btrfs\&.wiki\&.kernel\&.org\fR\m[] for further details\&.
