Hello,
I just got a BUG on mount of a raid10 fs. /dev/sde was added to
the fs recently and balance has been started. After reboot (balance
still running), the fs can not be mounted any more.

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

You have mentioned two issues when balance and fi show running

Hello Gui,
Oh, it seems that there are btrfs with missing devs that are bringing
troubles to the @open_ctree_... function.
what do you mean by missing devs? I have no degraded fs.

I have trouble finishing btrfs balance on five disk raid10 fs.
I added a disk to 4x3TB raid10 fs and run btrfs balance start

below. btrfs check does not find any errors, both before the balance
