Time has come for the YaST Team to pay the debts from the previous report:

- We promised some news about Cockpit and we have a whole new Cockpit module to present. - We mentioned our talk in the openSUSE + LibreOffice Virtual Conference and now we have the video for you. - We told you we were working on several changes in YaST and it's time to present them all, including big enhancements in the Partitioner UI and other usability improvements.

Check the whole report at https://yast.opensuse.org/blog/2020-11-10/sprint-112

Cheers. That really looks nice.

Since there is improvement in btrfs handling - a question/feature request:

Is it possible to add devices to already existing btrfs filesystems in YaST? Last time i tried it was only possible when creating new btrfs, but not adding a device to an existing btrfs. That would be cool for servers. I managed the task on the command line, but YaST might be a good place :-)

No. It's not possible because that's a process that can involve moving data and other typically slow operations that are not always easy to control, like btrfs balancing. The YaST Partitioner is not a good tool for that kind of operations that are slow, can be asynchronous and need monitoring during the process.

Thanks for all the work on YaST!

Thanks you all for using it and promoting it! Cheers. -- Ancor González Sosa YaST Team at SUSE Software Solutions

Adding a device does not involve any data movement at all. Data movement could be used to improve data distribution but it is not necessary or directly related to adding devices.

Removing a device does initiate data evacuation; maybe you mean this?

Well, You are both right ;-) Adding alone does not move or copy data. But often one wants to convert the btrfs data and/or metadata to RAID- something. That starts to copy/move data. But with a warning to the user, this might be ok. How is that done when removing a user and its data in YaST? Ok deleting is fast on resent filesystems, but wasn't in former times. -- Mit freundlichen Gruessen, Andreas Vetter
