In a chroot environment we may not have /proc mounted, which makes btrfs receive freak out since it wants to know the base directory where are are mounted for things like clone and such. Give an option to specify where the mountpoint is in these cases so you can still do a btrfs receive in a chroot.

NAME
|
|
----
|
|
btrfs-receive - receive subvolumes from stdin/file.
|
|
|
|
SYNOPSIS
|
|
--------
|
|
*btrfs receive* [options] <mount>
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Receives one or more subvolumes that were previously
|
|
sent with *btrfs send*. The received subvolumes are stored
|
|
into <mount>.
|
|
|
|
*btrfs receive* will fail with the following case:
|
|
|
|
1. a receiving subvolume already exists.
|
|
|
|
2. a previously received subvolume was changed after it was received.
|
|
|
|
3. default subvolume is changed or you don't mount btrfs filesystem with
|
|
fs tree.
|
|
|
|
After receiving a subvolume, it is immediately set to read only.
|
|
|
|
`Options`
|
|
|
|
-v::
|
|
Enable verbose debug output. Each occurrence of this option increases the
|
|
verbose level more.
|
|
-f <infile>::
|
|
By default, btrfs receive uses stdin to receive the subvolumes.
|
|
Use this option to specify a file to use instead.
|
|
-C|--chroot::
|
|
Confine the process to <mount> using chroot.
|
|
-e::
|
|
Terminate after receiving an <end cmd> in the data stream.
|
|
Without this option, the receiver terminates only if an error is recognized
|
|
or on EOF.
|
|
--max-errors <N>::
|
|
Terminate as soon as N errors happened while processing commands from the send
|
|
stream. Default value is 1. A value of 0 means no limit.
|
|
-m::
|
|
The root mount point of the destination fs.
|
|
+
|
|
By default the mountpoint is searched in /proc/self/mounts.
|
|
If you do not have /proc, eg. in a chroot environment, use this option to tell
|
|
us where this filesystem is mounted.
|
|
|
|
EXIT STATUS
|
|
-----------
|
|
*btrfs receive* returns a zero exit status if it succeeds. Non zero is
|
|
returned in case of failure.
