Hi, in short, this is a _must_ upgrade for every use that uses DRBD in the SDS use-case. I.e. with diskless primaries. Two bugs where identified that can cause DRBD to return wrong data to read requests on the diskless primary node. drbd 9.0.9-1 (api:genl2/proto:86-112/transport:14) -------- * fix occasionally forgotten resyncs in installations where diskless primaries are present. The bug tigers when a storage node is re-integrated, and it happens to connect to the diskless primary first; This bug is severe, since it might cause inconsistent data read back on the diskless primary! * fix an issue that causes unexpected split-brain situations upon connect. This issue triggers only when one of the node has a node_id bigger than 3 * in a cluster with a diskless primary, when a server goes away, and is not outdated, outdate it upon reconnect. This gets done when it's current UUID does not match the diskless primaries exposed data UUID; with this bug present it can lead to inconsistent data presented on the diskless primary node to readers * fix update of exposed data UUID on diskless primaries. It could lead to false reject of further diskfull secondaries that want to join * fix a possible OOPS when in a debug message regarding bitmap locking * fix discard bigger than 1MiB; The bug causes disconnect with bigger discard requests * fix left over bits in bitmap on SyncSource after resync; the issue was triggered by write requests that come in while the resync starts * fix peers becoming unexpectedly displayed as D_OUTDATED at the end of a resync; While the disk state on the node stays D_UP_TO_DATE * fix a race between auto promote and auto demote of multiple volumes in a single resource; The symptom was that the a process opening the /dev/drbdX for read-write gets an -EROFS errno * Speed up down of many resources by using call_rcu() instead of synchronize_rcu() * Make it compatible with the soon to be released 4.13 kernel http://www.linbit.com/downloads/drbd/9.0/drbd-9.0.9-1.tar.gz https://git.linbit.com/drbd-9.0.git/tag/refs/tags/drbd-9.0.9 drbd-utils 9.1.0 -------- * allow events2 --now polling * fix ambiguous inheritance for peer-device-options * fixup fallback path for BLKZEROOUT for older kernels * fix v9 proxy support * modernized XEN scripts * reproducible builds support * create-md --force for v8.4 (for compat to v9) * fix cstate output * resize: give resize more time (same as attach) * drbdmon: peer-device status, version info, node name * "drbdadm status" for v8.4 * set peer-device-options only once http://www.linbit.com/downloads/drbd/utils/drbd-utils-9.1.0.tar.gz https://git.linbit.com/drbd-utils.git/tag/refs/tags/v9.1.0
