[opensuse] /tmp mounting question
I need to replace the btrfs /tmp volume mounted on my Leap 42.3 system with a separate partition. The thing is, the new one will not be a btrfs volume. Surely it makes no difference if I comment out the existing btrfs line: UUID=dec8ab38-419f-46e3-bb03-c72b2688a142 /tmp btrfs subvol=@/tmp 0 0 and add something like this: /dev/sda3 /tmp ext4 defaults 0 0 And then reboot. Right? /dev/sda3 is formatted (obviously) but otherwise empty. I am always suspicious of what btrfs volumes are up to... -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

As far as I know, right :-) Instead of rebooting, you could do it all from a rescue system, too. Or from runlevel 1.

I did the switch. As a result, I lost a volume. And it is still gone when I put pack the original tmp volume: UUID=2d07fbed-6f8a-4662-9ad2-2fd602e59e1d /var/lib/docker btrfs defaults 0 0 It cannot find the UUID. I wonder if that changed when I changed the disk setup? The only UUIDs I see in /dev/disk/by-uuid/ are to the /dev/sda disk. I have no idea what this refered to. I do have a file called /var/lib/docker-storage.btrfs. Maybe that is what was mounted on /var/lib/docker? Of course, the whole reason I did the switch in the first place was that I needed more /tmp for a docker thing (running kiwi in dice). So of course that would be the volume that goes away... -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I didn't know it was related to dockers. I know close to nothing about them, but heard some strange things. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)

I'm not certain what the issue was. I restarted the docker daemon (even though I had rebooted the system), and now docker is working again. I can run kiwi in dice (which uses a vagrant container that is provided by docker). And the even more strange thing is that I understand what I just typed... :) -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
