[DRBD-announce] drbd-8.4.4.tar.gz

[Philipp Reisner]

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
