OK, I've found the reason.

There were two paths exported with same attributes:

/tftpboot -ro -mapall=nobody
/vol/tank1 -ro -mapall=nobody

As long as there is a filesystem mounted on /vol/tank1, above exports
will work. Since I've disconnected that drive, there was nothing mounted
this time.

Apparently mountd does not allow exporting multiple paths from a single
filesystem on separate lines if they happen to have identical attributes.
