Changelog for drbd-debugsource-9.0.22~1+git.fe2b5983-lp152.2.2.1.x86_64.rpm :

* Tue Mar 10 2020 nick wang - bsc#1166298, Update to drbd-9.0.22-1
* introduce locking to avoid connection retries when UUIDs or relevant flags change during the exchange of this data
* improve serialization of events after loosing a primary
* fix a constraint in sanitize state that can caused a promote to be deliced by some other node
* fix a case of a false positive detection of a split brain condition
* allow a resync target to switch to the resync source with less bits out of sync
* fix bitmap UUID after resync to use current UUID from self rather than sync source
* fix pushing bitmap UUID into history when changed
* fix regression introduced with 9.0.20, that can cause a missed resync after a reconciliation resync
* fix regression introduced with 9.0.20, that can cause a missed resync after a promote on a diskless node
* fix UUID handling in case a node promotes during (a short) reconciliation resync
* fix removing of a diskless node when quorum is enabled
* Tue Feb 25 2020 nick wang - Update to drbd-9.0.21-1, require coccinelle >= 1.0.8
* fix compat for write same on linux 4.9 and the Debian users
* fix kernel compat for linux 4.8 and 4.9; this mainly affected Debian users; The symptoms where slow resync and resync getting stuck always at the same point
* enable resync of lost and re-created backing devices (think lost node) when the backing device was thinly provisioned and its current uuid is pre-set to a \'day0 UUID\' (by LINSTOR); that works by copying a unused bitmap slot which tracks all changes since day 0
* fix attach when bitmap is on PMEM; before it was set to \'all blocks out-of-sync\' upon attach
* avoid doing reconciliation resync multiple times by updating the resync target\'s dagtag after if completed successfully
* return disk-state from Outdated to UpToDate when it loses connection while in WFBitMapT and we have a stable and UpToDate peer
* new option --force-resync flag can be passed to new-current-uuid, that can be used to trigger initial resync without touching the role- Remove upstream drbd-update-resync-target-s-dagtag.patch- Modify patch suse-coccinelle.patch to adopt spaas
* Fri Jan 03 2020 nick wang - bsc#1159786, fix build issue against v5.5 add patch without_pr_warning.patch
* Thu Dec 26 2019 nick wang - bsc#1159333, back port patch for duplicate resync. add patch drbd-update-resync-target-s-dagtag.patch
* Mon Dec 16 2019 nick wang - bsc#1158446, fix metadata limit due to 64k page size of ppc64le. add patch drbd-fix-zero-metadata-limit-by-page-size-misaligned.patch
* Thu Oct 17 2019 Richard Brown - Remove obsolete Groups tag (fate#326485)
* Fri Oct 11 2019 nick wang - Update to drbd-9.0.20-1
* fix a case of false split brain detection if a diskless node promotes multiple times, by aligning the rules for generating a new current-UUID on a diskless nodes with them on a node with disk
* check if we still have quorum by exchanging a drbd-ping with peers before creating new current UUID after loosing one peer
* fix after weak handling to not interfere with reconciliation resyncs
* retry connect when one of the relevant flags changes during UUID exchange
* fix reconciliation resync if one of the secondary got an current-UUID update
* fix resync to make progress after it was paused by an other resync operation
* fix false split-brains when a resync source changes current-UUID during resync operation
* fix restore of D_OUTDATED when the resource first only attached and then the peer objects are created (in contrast to the usual, new-peer, attach, connect)
* abort creating new current-UUID when writing to meta-data fails in the moment where the new-current-UUID should be written
* removed DRBD marking itself as read-only when secondary; this flag was exposed using the BLKROGET ioctl; that should be left to user-land use; recent KVM checks that flag, and does not dare auto-promote when set by DRBD
* fix a small memory-leak when creating peer devices
* fix a possible information leak of kernel memory that pads net-link packets
* completing implications of \"allow-remote-read=no\"; i.e. when not to create a new-current-UUID as read-write access to the data set was lost; also fail both reads and writes if reads are no longer possible
* new option value \"rr-conflict=retry-connect\"; that helps in scenarios with quorum where stopping a service takes longer than a temporarily network outage and DRBD\'s reconnect
* code cleanups, introduced enums for remaining magic numbers
* new kernel-backward-compatibility framework based on spatch/coccinelle, replacing an unmaintainable moloch of C preprocessor hell; Merged the complete kernel-compat submodule
* ships with pre-computed compat-patches for main distros\' kernels; in case an other kernel is found it tries to use local spatch, if that is not installed the build process tries to use a LINBIT hosted web service to create the compat patch (\"spatch-as-a-service\").
