Hi, In this cycle we where driven by users using DRBD9 with OpenStack. So we got improvements in handling many resources event to the extent of a new tool to get an quick overview of many DRBD resources. drbdmon drbdmon displays on limited screen space as much information as possible about as many resources as possible. It is an interactive display, i.e. it updates the screen as changes happens. The other highlights are performance optimization of activity log updates on secondaries and quicker connect times. Please note that drbd-9 still does not come with nice pacemaker integration (no crm-fence-peer, no ocf resource agent). This is an area where drbd-9 is not yet complete, and we will address this as soon as possible. DRBD 9.0.6-1 (api:genl2/proto:86-112/transport:14) -------- * fixed error handling in del_path * merge fixes from drbd-8.4; a potential NULL deref with kernel_sendmsg() * fix multiple issues with concurrent two-phase-commits * improve connect time; with older releases it usually took between 20 to 40 seconds to establish a connection; now it usually works now in less than 2 seconds * allow multiple updatese per AL-transaction on a secondary; this can (depending on the IO pattern) dramatically increase the the write throuput and decrease IO amplification * reorganize data structures of receiver for efficiency * upon an open for read-only access, wait for up the auto-promote-timeout for accessible data http://www.drbd.org/download/drbd/9.0/drbd-9.0.6-1.tar.gz http://git.drbd.org/drbd-9.0.git/tag/refs/tags/drbd-9.0.6 8.9.10 -------- * new drbdmon tool, which provides a compact overview about resources. In contrast to drbdsetup status it provides live monitoring. This requires a C++11 compiler. * drbdadm parser got substantially faster for thousands of resources * send SIGKILL to childs if parent (drbdadm) dies. http://www.drbd.org/download/drbd/utils/drbd-utils-8.9.10.tar.gz http://git.drbd.org/drbd-utils.git/tag/refs/tags/v8.9.10 cheers, Phil
