I started an upgrade from 15.0 to 15.1 following the instructions on this page: https://en.opensuse.org/SDB:System_upgrade All packages were download and the installation proceeded, but about half an hour ago, it appears to have gotten hung up at this point: (3814/4940) Installing: zypper-needs-restarting-1.14.27-lp151.1.2.noarch ............................................[done] (3815/4940) Installing: zypper-lifecycle-plugin-0.6.1490613702.a925823-lp151.3.1.noarch .............................[done] Additional rpm output: Updating /etc/sysconfig/lifecycle-report ...

If you are using btrfs I think you have to wait it out.

The root file system for Leap is ext4 (on the same machine I also installed TW on btrfs). ps afxu | grep -i btrfs shows this:

And apparently, you have it mounted.

Unlucky. Yes, me would have, perhaps, umounted it before starting the procedure, because /I/ knew about this possible problem.

CPU load is almost nil, so it that tells us nothing this time. But it maybe it would be interesting to see a few more lines. Maybe, as mentioned by Aaron there is a lot of i/o, but I have my doubts because you have "0.0 wa", ie, cpu waiting on i/o. To make sure, you could use "iotop" instead, but this command is not typically installed - and with rpm stuck you can not install anything else.

I don't know. Till now, all occurrences of this problem was to people with no btrfs partition. Maybe, there being no CPU activity, and little disk activity, you could kill the processes affected. First defrag (it is a guess), and last the systemctl service. I'm hopping here that the service then continues and the rpm script thinks things succeeded and continues with next part. -- Cheers / Saludos, Carlos E. R. (from 15.0 x86_64 at Telcontar)

Yes, as I wrote in my followup to Patrick Shanahan, I've done online upgrades with other mounted partitions, but never btrfs partitions. After I looked through the bug reports, I thought it was rather irresponsible that no mention of this is on the upgrade web page, which I was following.

As I wrote in my other followup, I did kill the process and the installation then completed and Leap 15.1 seems to be fine. But as I also wrote, my ill-informed attempt to unmount the TW partition resulted in blowing it away, so I have to reinstall it.

Yes.

Unlucky.

Yes, me would have, perhaps, umounted it before starting the procedure, because /I/ knew about this possible problem. I reported it months ago on a virtual machine, but we could not reproduce it and find out what caused it (it happens randomly, and so far, not to the people that can study it).

Why would a normal person umount other partitions, there is no reason really. And the install procedure /might/ install things appropriate for those mounts or apply configs or who knows.

Yes, as I wrote in my followup to Patrick Shanahan, I've done online upgrades with other mounted partitions, but never btrfs partitions. After I looked through the bug reports, I thought it was rather irresponsible that no mention of this is on the upgrade web page, which I was following.

Yes, there should be a note; maybe few people have seen this problem and the people writing them were not aware. You could open a bugzilla on that documentation or release notes issue.

I don't follow. You doubt it will help to kill the btrfs-defrag-plugin.py process, but it's ok to try? Or do you think it could do damage to the btrfs system or cause some other problem?

I fear that it could be problematic to kill it, I'm unsure.

And what about killing 'try-restart btrfsmaintenance-refresh.service'? What if I try to unmount the btrfs partition now? Or is it too late?

I don't know.

Till now, all occurrences of this problem was to people with no btrfs partition.

Maybe, there being no CPU activity, and little disk activity, you could kill the processes affected. First defrag (it is a guess), and last the systemctl service. I'm hopping here that the service then continues and the rpm script thinks things succeeded and continues with next part.

As I wrote in my other followup, I did kill the process and the installation then completed and Leap 15.1 seems to be fine. But as I also wrote, my ill-informed attempt to unmount the TW partition resulted in blowing it away, so I have to reinstall it.

Gosh :-( Next time, umount it with the option "--lazy", then wait patiently. "lsof" may tell you what program is using it. -- Cheers / Saludos, Carlos E. R. (from 15.0 x86_64 at Telcontar)

Check which processes are running. It's quite possible that the installer script has started some btrfs maintenance (balancing and scrubbing). Depending on many factors, this can take half an hour or more. In the mean time, you should see a lot of I/O to your disks. Regards, -- Aaron "Optimizer" Digulla a.k.a.

Does that apply to a non-root partition? As I mentioned in another reply, Leap is on ext4 but I also have TW on btfs and it's mounted under Leap.

I don't think there is a lot of I/O, going by the top info I posted in another reply. And the hangup is now more than 90 minutes. Can I safely kill the btrfs-maintenance process? Should I first unmount the btrfs partition? And if I can't? Steve Berman -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

you probably cannot umount the partition as it will be busy. a reboot would be the only solution. but do you really need that drastic a solution? is the process causing you that much difficulty that you cannot allow it to continue for an hour or two? next time you do an "install", leave any not absolutely required processes to be added after the install is completed when you can revert changes safely and easily w/o harm, ie: mounting a partition not necessary for the install (easy to add after install completed). -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri Registered Linux User #207535 @ http://linuxcounter.net Photos: http://wahoo.no-ip.org/piwigo paka @ IRCnet freenode -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I waited 2.5 hours and, since programs in the running system were becoming unusable due to the incomplete installation, decided to kill the btrfs-maintenance process, and immediately the installation proceeded and finished, and I rebooted into Leap 15.1 and it seems to be fine. However,...

...

next time you do an "install", leave any not absolutely required processes to be added after the install is completed when you can revert changes safely and easily w/o harm, ie: mounting a partition not necessary for the install (easy to add after install completed).

Yes this was a mistake. I've done online upgrades of previous openSUSE installations and if memory serves other systems were mounted and there were no problems, so it didn't occur to me to do otherwise now. But I've also never had a system on btrfs before. After the upgrade to 15.1 completed, I decided to remove the TW mount point, but the YaST partitioner wouldn't let me do it, saying the partition is busy. In my ignorance of btrfs I thought deleting the subvolumes might help, since these are also listed in /etc/fstab. And indeed, after deleting them, I could unmount the partition. But trying to boot TW failed with the error "file `/@/.snapshots/1/snapshot/boot/vmlinuz-5.1.3-1-default' not found." Evidently, deleting the subvolumes in the YaST partitioner blew TW away: I can mount the partition in Leap, but it is virtually empty (it contains the directories /boot, /etc and /usr, but the only nondirectory file is /etc/snapper/configs/root), and running btrfs restore on the unmounted partition saves these files and nothing else. So I have to reinstall TW. Steve Berman -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

What a lot of people have been asking in the past over and over again, pretty much ever since these btrfs and scripts started coming into existence, is, that why are they being executed and even used on non btrfs situations and machines? Please suse folks, what a shame, why are you wasting my cpu for exactly one minute on a zypper dup towards the end when i have nowhere on this machine anything with btrfs or even half a mile around this place. How come there is btrfsdefrag .pl something and some second related script? why oh why is btrfs trying to mess with stuff when there is no btrfs at all? :( -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
