Topic: Warning in Gparted related to a brtrfs partition.

Hi,

I have a large btrfs partition on my SSD drive. There's a warning in Gparted related to this parttion saying:

Label: 'ubuntu'  uuid: bfec7a12-14f1-4a95-a1d2-d04c8036a949
    Total devices 1 FS bytes used 125.00GiB
    devid    1 size 448.76GiB used 130.02GiB path /dev/sda1

Btrfs v3.14.1

What does this mean, should I worry about it and is there anything I should/could do about it?

I'm running Ubuntu 14.10 x64 with Gparted 0.19.0

Re: Warning in Gparted related to a brtrfs partition.

I suspect the error message is related to a problem with GParted trying to determine the file system usage statistics.

What version of GParted are you using, and on what GNU/Linux OS?

Would you be able to provide the output from the following three commands?

sudo parted /path-to-your-device unit s print

where /path-to-your-device is something like /dev/sda

sudo btrfs filesystem show /path-to-your-btrfs-partition

where /path-to-your-btrfs-partition is something like /dev/sda1

sudo blkid

I'm running Ubuntu 14.10 x64 with GParted 0.19.0-1build1 (from the Ubuntu repos).

The output you asked for:

Re: Warning in Gparted related to a brtrfs partition.

This appears to be an exact match for Bug 733601 - Btrfs: Warnings and missing label with btrfs-progs 3.12 and 3.14 which was fixed in GParted release 0.20.0.

Quoting a bit of the commit message for Update parsing of btrfs filesystem show for the UUID (#733601):

'btrfs filesystem show /dev/PTN' command is used to query details of a btrfs file system. When the file system is mounted the command reports failed exit status 1, but only when using btrfs-progs v3.14 and v3.14.1. This causes GParted to: (1) report warnings from the failed commands for a mounted btrfs file system, (2) fail to determine file system usage figures and (3) fail to display the mount point and busy indicator for non-mounting devices in multi-device btrfs file systems. The label is also read using the secondary blkid method via the FS_Info cache.

Thanks,
Mike

Re: Warning in Gparted related to a brtrfs partition.

Thanks.  I upgraded GParted to 0.20.0 and the warning/error is gone.
