Hi,
This is a bugfix only release in of the 8.3 code branch.
This release has a number of fixes important for long distance
replication setups. (Items 1, 3, 5, 6, 7 = 5 fixes)
Two fixes people that use backing devices where IO errors might
occur. (plain disks, or iSCSI with a non infinite time to retain)
Item 8 is a fix for a regression introduced with 8.3.9
Item 9 fixes for the 1PiByte support introduced with 8.3.10
Item 10 fixes a bug was there since the early days, but it got more
likely to trigger with DRBD's rather recent ability to use
bigger BIO sizes
Item 11 This issue was there since the early days, nobody noticed
it before
Although nearly of these fixes are for bugs that are very unlikely to
trigger, we recommend upgrading to 8.3.11.
8.3.11 (api:88/proto:86-96)
--------
* Added missing spinlock in compressed bitmap receive (regression introduced
in 8.3.10, could lead to "negative" out-of-sync stats and non-terminating
resync when "use-rle" is enabled)
* Fixed handling of read errors during online verify runs
* Fixes for possible distributed deadlocks during online verify and
checksum based resync processes
* Fixed handling of IO errors with an on-io-error=pass-on policy; the
disk state goes to inconsistent
* Fixed the behavior in case ping-timeout and ping-int are set to the
same value
* Fix for connecting on high latency network links
* Fixed wrong connection drops ("PingAck did not arrive in time") with
asymmetrically congested networks
* Fixed state transitions if fence-peer handler returns after connection was
established again
* Fixes to drbdmeta and drbdsetup for the > 16TByte support
* Made negotiation of max_bio_size conservative instead of optimistic
* Network timeouts for mirrored write requests are now always enforced,
no longer only when the socket is congested
