Post #1 of 1
It happened again. Only hour after the release was finally tagged,
an important issue was found. Do not use 8.0.9!
* Fixed a race condition in the disconnect code path that could cause
the pending count to not return to zero. This means that the
next role change will block forever.
* In case our backing devices support write barriers and cache
flushes, we use these means to ensure data integrity in
the presence of volatile disk write caches and power outages.
* Fixed DRBD to no longer log
"Sync bitmap getting lost (drbd_bm_set_bits_in_irq: (!b->bm))"
endlessly after the local disk was lost.
* Fixed protocol A for BIOs larger than the page size. If you
hit the bug, DBBD would simply lose connection.
* Don't accidentally truncate the device in case a secondary with
a too small disk gets connected.
* Changed state processing so that state changes visible
via the drbdsetup events interface are always in the right order.
* Made drbddisk's exit codes more LSB compliant.
* Back-ported the new drbdmeta to drbd-8.0 (from drbd-8.2).
* More robustness to the code that establishes connections.
* Made '/etc/init.d/drbd status' to print a nice overview.
* Made it to compile on Linux-2.6.24.
