btrfs open_tree() failed

[Kai Baker]

My system failed to suspend properly and now I get the error: open_ctree failed. Is my system completely fucked or is there a way to fix this?

I did a btrfsck —readonly and there are a lot of “extent” errors. A lot of “wanted XXXX but found YYYY”. I think the only thing I can do is attempt a repair. However, there’s supposedly a lot of risk doing that. The partition is not mountable so idk how I can attempt a backup before I try it. I thought btrfs was finally safe to use since it was available with the Opensuse installation.

I'd recommend dd'ing the drive if you can have a spare drive, then work against that.

I looked it up and I have a few options. However, I will dd it to a fresh hard drive before attempting to repair it. There’s also a recover option that I can attempt even with an unmounted partition. I will do that first because if I can’t save it then maybe I can recover most of my data and install a fresh installation with ext4 instead. I’ll report my success or failure to the group once I finish. There isn’t a lot of documentation for btrfs so it should be an interesting case study.
