Recommended update for DRBD
SUSE Recommended Update: Recommended update for DRBD
This update updates the Distributed Replicated Block Device
(DRBD) component of SLES HAE 11 SP3 to version 8.4.4,
providing many fixes and enhancements.
Changes included in the user land packages:
* New drbd-proxy option "bwlimit"; allow proxy options
on host level
* crm-fence-peer: less cib polling, peer-alive
detection using crmadmin, and other improvements
* ocf ra: avoid too tight pacemaker driven recovery
loop on failed promote, implement adjust_master_score
parameter
* drbdadm adjust now deals with IP-address changes
correctly
* Make sure old binary paths are still accessible.
Changes included in the kernel modules:
* Fix potential deadlock when concurrently fencing and
establishing a connection
* Fix potential distributed deadlock during verify or
resync
* Fix decoding of bitmap vli rle for device sizes > 64
TB
* Fix for deadlock when using automatic
split-brain-recovery
* Only fail empty flushes if no good data is reachable
* Avoid to shrink max_bio_size due to peer
re-configuration
* Fix resume-io after reconnect with broken fence-peer
handler
* Fix too large bursts for very slow resync rates
* Don't let application IO throttle resync to a stall
* Fix a hole in the challenge-response implementation
* Fix a theoretical IO deadlock (only triggers with
unusual small AL i.e. 7)
* Fix attaching to disks with fixed size external
meta-data (bnc#833764)
* Fix NULL pointer deref in module init error path
(bnc#825657)
* Fix a crash when the connection broke at a very exact
point in time while a graceful disconnect executes
* Support for REQ_DISCARD
* Allow parallel promote/demote
* Allow online changing of al-stripes and
al-stripe-size with the resize command.
