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 http://www.linbit.com/support/drbd-8.4.4/ http://git.drbd.org/gitweb.cgi?p=drbd-8.4.git;a=tag;h=refs/tags/drbd-8.4.4 http://oss.linbit.com/drbd/8.4/drbd-8.4.4.tar.gz Best, Phil
