Thanks for the hint…Where should i add this line? I am not familiar on this type of stuff… you can try that from rescue cd, gparted-live-cd is my personal favourite, and do something like this in terminal: sudo su - root mkdir /mnt/sda3 mount -t btrfs -o clear_cache /dev/sda3 /mnt/sda3

if that command succeeds then clearing cache helped and you can try rebooting to your main system. Otherwise you have different problem, maybe someone else will be able to advice something. -- To unsubscribe, e-mail:opensuse+unsubscribe@opensuse.org To contact the owner, e-mail:opensuse+owner@opensuse.org

Okay, i tried it within a terminal in ubunut which is the second system i am running on my laptop…

sudo mount -t btrfs -o clear_cache /dev/sda3 /mnt/sda3 mount: Falscher Dateisystemtyp, ungültige Optionen, der Superblock von /dev/sda3 ist beschädigt, fehlende Kodierungsseite oder ein anderer Fehler Manchmal liefert das Systemprotokoll wertvolle Informationen, versuchen Sie »dmesg | tail« oder so

and dmesg tells the following:

dmesg | tail [ 514.164113] parent transid verify failed on 35295068160 wanted 41939771539587072 found 25424 [ 514.164117] BTRFS: failed to read chunk root on sda3 [ 514.182238] BTRFS: open_ctree failed [ 593.703113] BTRFS info (device sda3): force clearing of disk cache [ 593.703118] BTRFS info (device sda3): disk space caching is enabled [ 593.703120] BTRFS: has skinny extents [ 593.711602] parent transid verify failed on 35295068160 wanted 41939771539587072 found 25424 [ 593.723735] parent transid verify failed on 35295068160 wanted 41939771539587072 found 25424 [ 593.723742] BTRFS: failed to read chunk root on sda3 [ 593.741048] BTRFS: open_ctree failed

Almost the same as in my first mail…Any suggestions? This looks quite critical…and…i don't have a recent update!!!

You haven't mentioned which version of opensuse you are running, and more importantly, which kernel. You'll probably get more help on thelinux-btrfs@vger.kernel.org list. First question they'll ask is are you running an up to date kernel and an up to date version of btrfs-progs.

Bob -- Bob Williams System: Linux 4.1.13-5-default Distro: openSUSE 42.1 (x86_64) with KDE Development Platform: 4.14.10 Thanks for the hint… Here are my specs:

System: Opensuse 42.1 Leap KDE Plasma: 5.4.3 Qt: 5.5.1 Kernel: 4.3.0-2-default

unfortunately I have no access to my system, so I do not know which versions of btrfs-progs i have. But my system is up to date (lateste update 2 days ago). Thanks!

(sorry Bob for sending you a private mail…was a mistake!)

I do not know why, but it seems, that something has rotten my btrfs filesystem of my root partition (sda3)… I could solve the issue by running: See: http://askubuntu.com/questions/157917/how-do-i-recover-a-btrfs-partition-tha... I did: |btrfs-zero-log /dev/sda5| This made the partition mountable again. Thanks for hints!
