Hello Satoru and all, that Oct. report was the only time I've experienced the error, so I don't have much to add. I can try to answer your questions: > >Here are my questions. > > > >1. Is your system "btrfs scrub" clean? yes, > >2. Is this message shown every boot time? no, I have seen them only during one boot > >3. Is this message shown only in boot? As in my Oct. email http://permalink.gmane.org/gmane.comp.file-systems.btrfs/39721 I've seen a similar one after creating a subvolume on a new fs. But it was during the same boot. > >4. When this message is started to be shown? > >5. Do you have any trouble, change your operation or configuration > > just before the answer of Q4 ? a disk was added to the fs and balance has been run. The balance crashed, as in https://bugzilla.kernel.org/show_bug.cgi?id=64961 (probably unrelated). After reboot, I've seen the messages. > Additional questions. > Q5. Could you give me your kernel configuration? > At least, could you tell me whether your kernel > enabled CONFIG_PREEMPT or not? CONFIG_PREEMPT_VOLUNTARY=y > Q6. If the answer of Q1 is correct, please give me the > file system image which can be captured by the following command. Sorry, the fs's are long gone. I continued to run similar workloads on that test box, but these errors never appeared again.
