Would you mind to provide the kernel version? And if possible please run a btrfs check --readonly on the device and provide the output. It could provide more info than the kernel message. BTW, this is indeed scary, but even some bad space cache sneaked into the kernel, at least latest upstream kernel can detect and error out more or less gracefully (by aborting current transaction and marking the fs RO, without writing the bad data onto disk). If you want a quick workaround, you can try "btrfs check --clear-space-cache v1" then mount the fs with "-o nospace_cache" or "-o space_cache=v2". Kernel: probably vmlinuz-4.12.14-lp151.28.25-default. I'm currently on vmlinuz-4.12.14-lp151.28.32-default. Since this is the root fs of my primary server, it's somewhat difficult to run a filesystem check. I'm going to try clearing the cache. /me crosses fingers...

Then please note that, "-o clear_cache" will only clear the cache of modified block groups, not all (unless you run a full fs balance). In your case, the kernel is SLE kernel, I'm not sure how good the v2 cache is supported. So I would recommend nospace_cache mount option just to be safe. BTW, is there any unexpected shutdown in the past? (In reply to Wenruo Qu from comment #3) > (In reply to Jon Nelson from comment #2) > > Kernel: probably vmlinuz-4.12.14-lp151.28.25-default.

Yes. There have been unexpected shutdowns.

At this point, it shows the fs is already corrupted before "btrfs check" doing anything to it.
I'm afraid that why the space cache is corrupted, because the metadata of the fs is already corrupted. And All later output also proves that.
Feel sorry for it.
I'm afraid you'd better try to salvage your data, as the chance of fully recovery is pretty low. (You can try btrfs check --repair, but that's not ensured to completely fix it, especially when there are transid mismatch)
