[DRBD-user] drbd-9.1.18-rc.1 and drbd-9.2.7-rc.1

[Philipp Reisner]

Hello,

Here comes the DRBD December release. drbd-9.1.18-rc.1 and drbd-9.2.7-rc.1.
We have two updates that are worth mentioning.

One, the RDMA transport finally reaches general usability. As usual, I
have plans to improve it further, it never stops.

The other improvement is in the area of the quorum code. For a cluster
containing two nodes with backing disks and a diskless tiebreaker node,
our quorum implementation can preserve quorum on a single storage node
with the help of the tiebreaker node.

Up to now, it has lost quorum when that remaining storage node restarts.

Now we are improving that, it will restore quorum from the meta-data in
case it reboots.

Please help test the release candidates.


9.2.7-rc.1 (api:genl2/proto:86-122/transport:19)
--------
 * Fixed wrong tx-timeouts in the RDMA transport
 * Recreate buffers promptly for the RDMA transport, improving
   performance a lot
 * changes merged from drbd-9.1.18
  - Fixed connecting nodes with differently sized backing disks,
    specifically when the smaller node is primary, before establishing
    the connections
  - Fixed thawing a device that has I/O frozen after loss of quorum
    when a configuration change eases its quorum requirements
  - Properly fail TLS if requested (only available in drbd-9.2)
  - Fixed a race condition that can cause auto-demote to trigger right
    after an explicit promote
  - Preserve "tiebreaker quorum" over a reboot of the last node (3-node
    clusters only)
  - Update compatibility code for Linux 6.6
