I print the insteresting part of syslog below. I mount the disk with mount -t btrfs -o compress,noatime,nodiratime,noacl,noexec,nosuid /dev/sdb1 /usb
The error parts in the syslog come from the the mistaken "mount /usb" and the line /dev/sdb1 /usb auto defaults,noauto,noatime,nodiratime,users,noexec,nosuid,nodev,nobarrier,noauto_da_alloc,data=writeback 0 0 in fstab. I could not see other errors.
