Subject: [PATCH] drbd: Support zeroout device instead of initial full sync
|
|
||||||
|
|
||||||
Patch set for zeroing out device on both side
|
|
||||||
instead of initial full sync. Useful for high
|
|
||||||
latency network environment.
|
|
||||||
|
|
||||||
Implement --zeroout-devices and --discard-devices
|
|
||||||
for new-current-uuid

Drbd is a distributed replicated block device. It mirrors a block
|
||||||
|
device over the network to another machine. Think of it as networked
|
||||||
|
raid 1. It is a building block for setting up clusters.

Subject: [PATCH] fix failure with new bi_error field of bio
|
|
||||||
|
|
||||||
drbd fail to build with new bio structure and interface
|
|
||||||
after 4.3.0, see 4246a0b63bd8f56a1469b12eafeb875b1041a451
|
|
||||||
A new bi_error field to store an errno value directly in
|
|
||||||
struct bio and remove the existing mechanisms to clean
|
|
||||||
all this up.
|
|
||||||
|
|
||||||
With 8ae126660fddbeebb9251a174e6fa45b6ad8f932,
|
|
||||||
generic_make_request() is now able to handle arbitrarily
|
|
||||||
sized bios,it's no longer need to define its merge_bvec_fn.
|
|
||||||
|
|
||||||
This patch delete merge_bvec_fn and support new bio struct.
