After rebooting with this kernel:
[    4.469419] BTRFS error (device sdb1): super_total_bytes 1000203808768
mismatch with fs_devices total_rw_bytes 1000203812864

but the partition was properly mounted

> btrfs fi resize max /mnt/cache 

[  147.637427] BTRFS info (device sdb1): new size for /dev/sdb1 is
1000203816960

(proper command needs device name, not mount path)

total_bytes        1000203812864
dev_item.total_bytes    1000203816960

> btrfs inspect dump-tree /mnt/cache | grep total
        devid 1 total_bytes 1000203816960 bytes_used 426351001600
total bytes 1000203812864

I then unmounted /mnt/cache and re-mounted it (without rebooting):

[  405.607741] BTRFS error (device sdb1): super_total_bytes 1000203812864
mismatch with fs_devices total_rw_bytes 1000203816960

(but partition was mounted)
