drbd: new configuration parameter c-min-rate

2010-10-14T16:38:20+00:00

We now track the data rate of locally submitted resync related requests,
and can thus detect non-resync activity on the lower level device.

If the current sync rate is above c-min-rate, and the lower level device
appears to be busy, we throttle the resyncer.

drbd: Finished the "on-no-data-accessible suspend-io;" functionality

2010-10-14T12:52:53+00:00

When no data is accessible (no connection to the peer, nor a local disk)
allow the user to select to freeze all IO operations instead of getting
IO errors.

drbd: revert "delay probes", feature is being re-implemented differently

2010-08-07T16:53:57+00:00

It was a now abandoned attempt to throttle resync bandwidth
based on the delay it causes on the bulk data socket.
It has no userbase yet, and has been disabled by
9173465ccb51c09cc3102a10af93e9f469a0af6f already.
This removes the now unused code.

The basic feature, namely using up "idle" bandwith
of network and disk IO subsystem, with minimal impact
to application IO, is being reimplemented differently.

drbd: Four new configuration settings for resync speed control

2010-05-17T23:25:00+00:00

To reasonably control resync speed over drbd-proxy connections,
drbd has to measure the current delay of packets transmitted over
the (possibly congested) data socket vs the meta-data socket.
