Hi,
This again is a call for all DRBD users, that have some testing equipment
available, and are ready to contribute a bit of their time to testing
DRBD.
This is a release candidate, do not use it for production.
This is a release candidate, do not package it for distributions.
The most outstanding change with this release is, that DRBD now
can use multiple BIOs (single IO requests) for processing a signle
data packat on the receiving side. This allows DRBD in many more
cases than before (on LVM's LVs) to process BIOs of a size of up
to 32k. (Before that DRBD, in many cases, forced the whole stack
down to a max BIO size of 4k).
This is important for hardware setups where both disk IO subsystem
and connecting network operate in the area of 10GBit/sec. Those become
rapidly more common.
8.3.8rc1 (api:88/proto:86-94)
--------
* Do not expose failed local READs to upper layers, regression introduced
in 8.3.3
* Fixed support for devices with 4k hard sector size (again)
* Fixed a potential Oops in the disconnect code
* Fixed a race condition that could cause DRBD to consider the peers disk
as Inconstent after resync instead of UpToDate (Bugz 271)
* Fixed a reace condition that could cause DRBD to consider the peers disk
as Outdated instead of Inconsistent during resync (Bugz 277)
* Disallow to start a resync with invalidate / invalidate-remote when the
source disk is not UpToDate
* Forcing primary works now also for Consistent, not only for Outdated and
Inconsistent (Bugz 266)
* Improved robustness against corrupt or malicous sector addresses when
receiving data
* Added the initial-split-brain, it gets called also if the split-brain gets
automatically resolved
* Added the --assume-clean option for the resize command, it causes drbd to
not resync the new storage after an online grow operation
* drbdadm: Do not segfault if stacked-on-top-of refers to an undefined res
* drbdadm: Do not consider configs with invalid after statements as invalid
* drbdadm: Do not segfault if the peer's proxy section is missing
* drbdadm: Allow nullglob in include statement
* drbdadm: Fixed the use of waitpid
* init script: fix insserv headers (Debian 576901)
* Gave the receiving code the ability to use multiple BIOs for writing a
single data packet; now DRBD works with BIOs up to 32kByte also on LVM
devices; from now on the use_bmbv config option does nothing
* New command check-resize, that allows DRBD to detect offline resizing
and to move internal meta-data accordingly
* Added a control loop, that allows DRBD to find auto tune the resync
speed, on connections with large queues (drbd-proxy)
* Create new current UUIDs late, after loosing connection to the peer
* --dry-run option for connect; disconnects after sync handshake
* --overwrite-data-of-peer got an alias named --force
* Improvements to crm-fence-peer
* Fixed option parsing and stacking in snapshot-resync-target-lvm.sh
* Compiles on 2.6.33 and 2.6.34
