533 * "connection timed out". This is more or
534 * less the same as always, except that the servers
535 * may appear to bounce up and down while they
536 * are actually restarting.
537 * 2. return VBUSY which will cause clients to
538 * sleep and retry for 6.5 - 15 minutes, depending
539 * on what version of the CM they are running. If
540 * the file server takes longer than that interval
541 * to attach the desired volume, then the application
542 * will see an ENODEV or EIO. This approach has
543 * the advantage that volumes which have been attached
544 * are immediately available, it keeps the server's
545 * immediate backlog low, and the call is interruptible
546 * by the user. Users see "waiting for busy volume."
547 * 3. sleep here and retry. Some people like this approach
548 * because there is no danger of seeing errors. However,
549 * this approach only works with a bounded number of
550 * clients, since the pending queues will grow without
551 * stopping. It might be better to find a way to take
552 * this call and stick it back on a queue in order to
553 * recycle this thread for a different request.
554 * 4. Return a new error code, which new cache managers will
555 * know enough to interpret as "sleep and retry", without
556 * the upper bound of 6-15 minutes that is imposed by the
557 * VBUSY handling. Users will see "waiting for
558 * busy volume," so they know that something is
559 * happening. Old cache managers must be able to do
560 * something reasonable with this, for instance, mark the
561 * server down. Fortunately, any error code < 0
562 * will elicit that behavior. See #1.
563 * 5. Some combination of the above. I like doing #2 for 10
564 * minutes, followed by #4. 3.1b and 3.2 cache managers
565 * will be fine as long as the restart period is
566 * not longer than 6.5 minutes, otherwise they may
567 * return ENODEV to users. 3.3 cache managers will be
568 * fine for 10 minutes, then will return
569 * ETIMEDOUT. 3.4 cache managers will just wait
570 * until the call works or fails definitively.
571 * NB. The problem with 2,3,4,5 is that old clients won't
572 * fail over to an alternate read-only replica while this
573 * server is restarting. 3.4 clients will fail over right away.
