Reword several option descriptions, add missing short option -E, formatting adjustments. Visual bug fix: the first line is printed in short help, the second line is long description, thus alternative calling syntax must be printed on one line. Signed-off-by: David Sterba <dsterba@suse.com>

NAME
|
|
----
|
|
btrfs-receive - receive subvolumes from send stream
|
|
|
|
SYNOPSIS
|
|
--------
|
|
*btrfs receive* [options] <path>
|
|
|
|
or
|
|
|
|
*btrfs receive* --dump [options]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
Receive a stream of changes and replicate one or more subvolumes that were
|
|
previously generated by *btrfs send*. The received subvolumes are stored to
|
|
'path', unless '--dump' option is given.
|
|
|
|
If '--dump' option is specified, *btrfs receive* will only do the validation of
|
|
the stream, and print the stream metadata, one operation per line.
|
|
|
|
*btrfs receive* will fail int the following cases:
|
|
|
|
1. receiving subvolume already exists
|
|
|
|
2. previously received subvolume has been changed after it was received
|
|
|
|
3. default subvolume has changed or you didn't mount the filesystem at the toplevel subvolume
|
|
|
|
A subvolume is made read-only after the receiving process finishes succesfully.
|
|
|
|
`Options`
|
|
|
|
-v::
|
|
increase verbosity about performed actions, print details about each operation
|
|
|
|
-f <FILE>::
|
|
read the stream from <FILE> instead of stdin,
|
|
|
|
-C|--chroot::
|
|
confine the process to 'path' using `chroot`(1)
|
|
|
|
-e::
|
|
terminate after receiving an 'end cmd' marker in the stream.
|
|
+
|
|
Without this option the receiver side terminates only in case
|
|
of an error on end of file.
|
|
|
|
-E|--max-errors <NERR>::
|
|
terminate as soon as NERR errors occur while stream processing commands from
|
|
the stream
|
|
+
|
|
Default value is 1. A value of 0 means no limit.
|
|
|
|
-m <ROOTMOUNT>::
|
|
the root mount point of the destination filesystem
|
|
+
|
|
By default the mountpoint is searched in '/proc/self/mounts'.
|
|
If '/proc' is not accessible, eg. in a chroot environment, use this option to
|
|
tell us where this filesystem is mounted.
|
|
|
|
--dump::
|
|
dump the stream metadata, one line per operation
|
|
+
|
|
Does not require the 'path' parameter. The filesystem chanded.
|
|
|
|
EXIT STATUS
|
|
-----------
|
|

|
|
