Bug 331121 – sys-fs/btrfs-progs-0.19: btrfsctl missing -D option

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description chester moy 2010-08-03 20:55:18 UTC]

Btrfsctl, the goto tool for btrfs management is missing the -D option which deletes a given subvolume. The option is listed in the Wiki and was also present in other distributions, but not available in the copy available in portage.

Reproducible: Always

Steps to Reproduce:
1. emerge btrfs-progs
2. mount a btrfs volume
3. create a subvolume or snapshot using btrfsctl

Now, there is no way to delete the snapshot or subvolume

Actual Results:  
btrfsctl states that no valid commands were given

Expected Results:  
btrfsctl -D subvolume dir
should delete the given subvolume

emerge -pv:
[ebuild   R   ] sys-fs/btrfs-progs-0.19  USE="acl -debug-utils" 0 kB

Also, added the URL to the btrfs wiki page on kernel.org

It appears that this is a post 0.19 feature.  And 0.19 is the "latest", although it is quite old (13 months).  I need to find out what the status is from upstream, since we really need to follow their releases.  Can you tell me what other distros support -D, and I'll go see how they managed this.

The other distro that had the option was Fedora. I'm actually switching to gentoo from Fedora (13), so i thought it came standard in the current btrfs tools.

[Comment 5 Joe Peterson (RETIRED) 2010-08-07 06:03:32 UTC]

It looks like Fedora's maintainer of btrfs-progs is Josef Bacik (from RedHat Linux), who is one of the btrfs developers, so I suspect he has inserted a "newer" version of 0.19 (i.e. newer than the official tagged 0.19 version) in that distro.

I'll contact Josef and see if I can find out what version that so that Gentoo can get the latest version as well.

Thanks for your work and enthusiasm. I appreciate the fact that you're willing to make a (later than 'latest') version of btrfsctl for Gentoo

Now using patch from RedHat (from Josef) in -r1.
