Hi,

it is a long time since the release of drbd-9.0.0. Many bugs have been
fixed, just as expected for the first maintenance release after a .0
release.

On the feature side, the support for multiple paths was completed. I.e.
you can configure multiple address pairs, and the TCP transport will
try all of those until it can establish a connection on one of the
pairs.
Apart from that the new features of 8.4.7 are merged. (WRITE_SAME,
resync of thinly provisioned storage)

For those who already run 9.0.0 please upgrade to 9.0.1 as soon as
possible.

And a BIG THANK YOU, to the members of the community that reported
bugs and regressions of 9.0.0.


drbd
9.0.1-1 (api:genl2/proto:86-111/transport:14)
--------
 * Fix ahead/behind mode: spinlock deadlock when entering and resync
   afterwards
 * Fix crash in online verify
 * Fix crash when receiving pages on a diskless node
 * Fix issues with resize when more than two nodes are present
 * Many minor fixes
 * Work on the multi-path support; the TCP transport now tries all paths while
   connecting, afterwards it uses one path
 * The RDMA transport supports multiple paths and can use them in parallel
 * Configuration option to make resync thinly provisioned storage
   friendly: rs-discard-granularity
 * Make sure it compiles with Linux 4.4
 * Merge changes from the 8.4.7 release
 * Fix a performance regression of 8.4.0; it got worse with bigger devices;
   really significant above 1TByte
