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