490 * 1. return -1, which will cause users to see
491 * "connection timed out". This is more or
492 * less the same as always, except that the servers
493 * may appear to bounce up and down while they
494 * are actually restarting.
495 * 2. return VBUSY which will cause clients to
496 * sleep and retry for 6.5 - 15 minutes, depending
497 * on what version of the CM they are running. If
498 * the file server takes longer than that interval
499 * to attach the desired volume, then the application
500 * will see an ENODEV or EIO. This approach has
501 * the advantage that volumes which have been attached
502 * are immediately available, it keeps the server's
503 * immediate backlog low, and the call is interruptible
504 * by the user. Users see "waiting for busy volume."
505 * 3. sleep here and retry. Some people like this approach
506 * because there is no danger of seeing errors. However,
507 * this approach only works with a bounded number of
508 * clients, since the pending queues will grow without
509 * stopping. It might be better to find a way to take
510 * this call and stick it back on a queue in order to
511 * recycle this thread for a different request.
512 * 4. Return a new error code, which new cache managers will
513 * know enough to interpret as "sleep and retry", without
514 * the upper bound of 6-15 minutes that is imposed by the
515 * VBUSY handling. Users will see "waiting for
516 * busy volume," so they know that something is
517 * happening. Old cache managers must be able to do
518 * something reasonable with this, for instance, mark the
519 * server down. Fortunately, any error code < 0
520 * will elicit that behavior. See #1.
521 * 5. Some combination of the above. I like doing #2 for 10
522 * minutes, followed by #4. 3.1b and 3.2 cache managers
523 * will be fine as long as the restart period is
524 * not longer than 6.5 minutes, otherwise they may
525 * return ENODEV to users. 3.3 cache managers will be
526 * fine for 10 minutes, then will return
527 * ETIMEDOUT. 3.4 cache managers will just wait
528 * until the call works or fails definitively.
529 * NB. The problem with 2,3,4,5 is that old clients won't
530 * fail over to an alternate read-only replica while this
531 * server is restarting. 3.4 clients will fail over right away.
