Hi,
It really got time to push an drbd-8.4 release out. Over the course
over the last 9 month (yes, 8.4.5 is already nine month old), no
major issues where discovered.
The major driving force in this time period are customers that want
to see more performance on their latest generation SSDs.
The final release is scheduled in one week from now.
Please help testing the release candidate.
drbd
8.4.6rc1 (api:genl1/proto:86-101)
-------
* fix failing of user space helpers since kernel 3.13. This bug is known as
'out of mem, failed to invoke fence-peer helper'
* fix connection timeouts for resources with multiple volumes
* fix an issue with DRBD on linux software raid by properly remapping
bi_bdev
* fix a (hard to trigger) race condition between promoting to primary an
connection handshake. In case the bug was hit the Primary got stuck in
WFBitmapS connection state
* Fix a NULL deref when resuming IO on a diskless primary
* Fix compile issues with uncommon architectures
* improvements to asender performance. With high end backing storage and
networking equipment you may see IOPS improvements between 25% to 50%.
Highest number on a single drbd seen by LINBIT so far: 160000 IOPS
* backport of events2 and status commands from drbd9. This allows to be
DRBD9 compatible starting with this release, and to get used to DRBD9
compatible status reporting
