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

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