Tumbleweed after Update to Kernel 3.17.1-52.1 has corrupted Btrfs Root Partition

[consused]

I just fixed my version of tumbleweed that was affected by this read-only snapshot bug. Here’s how I did it:

1. Note: I’ve heard this only works if you haven’t yet run the btrfs repair command. Keep your backups at the ready.
2. Upgrade to kernel-desktop 3.17.2 and btrfsprogs 3.17 via software.opensuse.org.
3. Note: I didn’t subscribe to their associated repos. The key is that from now on you don’t downgrade back to the old buggy versions.

Thanks for posting such a well-formatted procedure.

The corruption is one part of the failure, another is the persistent read-only state of the whole btrfs root partition (even without running btrfsck --repair). On my system, the latter appears to prevent the means to effect any software upgrade or any other changes on the file system. Therefore your “2. Upgrade to…” suggests that the read-only condition of the file system had not occurred on yours at that stage. Is that right?

I was under the impression from the openSUSE bugzilla that 3.17 version of btrfsck was required to first fix the read-only file system. Yes, that would need to be done via another operating system, before any upgrading could take place.

I assume you used Kernel:stable to source 3.17.2, but for btrfsprogs 3.17 there were only unstable “home:user” versions available, so which one did you use?
