Hi,
Apart from many fixes to the most outstanding new feature
of this release is Support for DISCARD requests
(in SCSI speak: unmap; ATA speak: trim). This is important
for use on SSDs or on thinly provisioned storage.
8.4.4 (api:genl1/proto:86-101)
--------
* Changes from 8.3.16
* 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
* 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
* fix too large bursts for very slow resync rates
* don't let application IO throttle resync to a stall
* Fixed a hole in the challenge-response implementation
* Fixed a theoretical IO deadlock (Only triggers with unusual small AL i.e. 7)
* Fixed attaching to disks with fixed size external meta-data
(This regressions was introduced with 8.4.3)
* Fixed 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
* drbdadm adjust now deals with IP-address changes correctly
* Align the internal object model with drbd-9.0 (away from drbd-8.3)
* New drbd-proxy option "bwlimit"; allow proxy options on host level
* Compiles on Linux v3.11
