Replica lag
The time difference between the state of the file system on the
replica and on the originator. A generic message of "Less
than 5 minutes" appears if the replica is either nearly caught up
with data from the originator or if the replica is caught up and
synchronized and the originator is not sending new data.
throttle add < sched-spec rate >
Add a scheduled time to change the rate of network bandwidth used
by replication. The < sched-spec > must include one or more three-
letter days of the week (such as mon , tue , or wed ) or the word
daily to set the schedule every day of the week, and a time off day
in 24 hour military time. The < rate > must include a number and, as
an option, whether that number is in bits or bytes per second. With
no bits or bytes specified, the default rate is bits per second. In
the rate variable:
bps or b equals raw bits per second
Kbps, Kb, or K equals 1024 bits per second
Bps or B equals bytes per second
KBps or KB equals 1024 bytes per second
The < rate > can also be 0 (the zero character), disable , or disabled
to stop replication, or unlimited to set the rate to the default of
no limit.
For example, the following command limits replication to 20
kilobytes per second starting on Mondays and Thursdays at 6:00 a.m.
replication throttle add mon thu 0600 20KB
Replication runs at the given rate until another scheduled change
or until other replication throttle commands force a change. The
default rate (unlimited) with no scheduled changes is to run as fast
as possible at all times.
The add command may change the current rate. For example, assume
that on Monday at Noon, the current rate is 20 KB, and the schedule
that set the current rate started on mon 0600 . If you now add a
scheduled change for Monday at 1100 at a rate of 30 KB ( mon 1100
30KB ), the change takes place immediately.
throttle del < sched-spec >
Remove one or more throttle schedule entries. The < sched-spec > must
include one or more three-letter days of the week (such as mon , tue ,
or wed ) or the word daily to delete all entries for the given time,
and a time of day in 24 hour military time.
