Comment 1 Jan Tulak 2018-11-15 12:29:44 UTC

Hi, thanks for the report.

Assuming you have a btrfs device somewhere, this is an already known issue and I have a patch available where I'm waiting if the original reporter can test it.

If you want to test it too, clone SSM's git repository from github and switch to branch btrfs-info-fix:

git clone https://github.com/system-storage-manager/ssm.git
git checkout btrfs-info-fix

And then run that version of ssm (<dir>/bin/ssm.local info) as you would the version in your system. Did it fix the issue?

Comment 2 Donald O. 2018-12-03 13:13:55 UTC

gone.

Comment 3 Jan Tulak 2018-12-04 08:50:41 UTC

I take it that the fix worked for you. That's good to hear, but it doesn't make the bug un-happen. It will go through the standard steps and I will close the issue when the patch lands in Fedora (a release is planned for the next week).

Comment 4 Donald O. 2018-12-04 09:15:37 UTC

Yes there are some btrfs file systems active.
I install ssm from fedora repository and don't intend to build ssm ever. Thus the patch can't work for me.

Comment 5 Jan Tulak 2018-12-04 09:25:02 UTC

The upstream link is only to see if it really is the same issue, if it gets fixed and a temporary workaround, not a permanent solution for you. I plan to push a new release that includes this fix into Fedora testing the next Monday, and then it will take a few days before it moves to Fedora stable.

Comment 6 Donald O. 2018-12-04 09:27:56 UTC

thanks  a lot Jan!

Comment 7 Jan Tulak 2018-12-04 09:30:39 UTC

Please, do not close the bug. I will do it myself when the fix gets to Fedora repo. Thanks.

Comment 8 Donald O. 2018-12-04 13:48:20 UTC

OK, Jan. Again thanks  a lot in advance.
