I recently let the Update Manager run after ignoring it for a couple of weeks. 
It required a reboot. My USB btrfs volume didn't mount after reboot. dmesg 
revealed:

[ 463.187097] btrfs: open_ctree failed
[ 991.567090] device label StoreW devid 1 transid 37077 /dev/sdb
[ 1003.171989] device label StoreW devid 1 transid 37077 /dev/sdb
[ 1003.207990] parent transid verify failed on 79466496 wanted 33999 found 36704

[ 1003.230889] btrfs: open_ctree failed

btrfs-show plainly enough finds my volume:

$ sudo btrfs-show
Label: StoreW uuid: e98e0ffd-3d0b-4b55-bacc-0d60797f0f29
Total devices 1 FS bytes used 1.79TB
devid 1 size 2.73TB used 1.90TB path /dev/sdb

Btrfs Btrfs v0.19

but everything else (like "btrfsctl -a") doesn't see it.

I've read dozens of pleas for "open_ctree" issues, but none of them had useful 
conclusions. Is there anything I can do?

Any help would be appreciated. Thank you. Please CC me on any replies.
