       btrfs-replace - replace devices managed by btrfs with other device.

       btrfs replace  

       btrfs replace is used to replace btrfs managed devices with other device.

           Cancel a running device replace operation.

           Replace device of a btrfs filesystem.

           On a live filesystem, duplicate the data to the target device which is currently
           stored on the source device. If the source device is not available anymore, or if the
           -r option is set, the data is built only using the RAID redundancy mechanisms. After
           completion of the operation, the source device is removed from the filesystem. If the
            is a numerical value, it is assumed to be the device id of the filesystem
           which is mounted at , otherwise is is the path to the source device. If the
           source device is disconnected, from the system, you have to use the devid parameter
           format. The  needs to be same size or larger than the .


               only read from  if no other zero-defect mirror exists. (enable this if
               your drive has lots of read errors, the access would be very slow)

               force using and overwriting  even if it looks like containing a valid
               btrfs filesystem.

               A valid filesystem is assumed if a btrfs superblock is found which contains a
               correct checksum. Devices which are currently mounted are never allowed to be used
               as the .

               no background replace.

       status [-1] 
           Print status and progress information of a running device replace operation.


               print once instead of print continuously until the replace operation finishes (or
               is canceled)

       btrfs replace returns a zero exit status if it succeeds. Non zero is returned in case of
