[Bug 1512116] Re: gparted ignores devid for btrfs filesystem

[Curtis Gedak]

Thank you Rolf for your interest in improving GParted.

This problem was fixed upstream in GParted 0.20.0.  See the following
upstream bug report:

GParted resizes the wrong filesystem (does not pass the devid to btrfs filesystem resize)
https://bugzilla.gnome.org/show_bug.cgi?id=723842

The latest version of GParted at time of writing is 0.24.0.
Unfortunately the versions packaged in Ubuntu are quite old.

Title:
  gparted ignores devid for btrfs filesystem

Status in gparted package in Ubuntu:
  New

Bug description:
  I used gparted to move and resize one of my partitions.  The partition
  in question uses btrfs.  The verification step failed because gparted
  does not specify the devid (something specific to btrfs it seems).
  "sudo btrfs filesystem resize max /tmp/gparted-h9AlSk" is the command
  line that was used and failed where it should have been "sudo btrfs
  filesystem resize 2:max /tmp/gparted-h9AlSk".

  TEST CASE:
  1) get or create a disk with a btrfs filesystem that has a different devid than 1.  Easiest way is probably to create two btrfs partitions.
  2) start gparted
  3) Run "Partition - Check" on the partition with a devid different from 1.

  The partition check will fail because btrfs assumes devid to be 1 if
  none is specified (as documented in "man btrfs").

         filesystem resize [devid:][+/-]<size>[gkm]|[devid:]max <path>
                Resize  a  filesystem  identified by <path> for the underlying
                device devid.  The devid can be found with btrfs filesystem 
                show and defaults to 1 if not specified.
