* Fixed a regression in resync decission code drbd_uuid_compare() [Bugz 260]Philipp Reisner2009-11-24
| | | | | | | | | | Since 8.3.3 we fail to do the resync when a partial resynch is not possible, but a full synch is necessary. This regression was introduced with 7101539930c0a89146959e7a39c09ad9c3516434 Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>
* add missing state change on corrupt packet header in drbd_recv_headerLars Ellenberg2009-11-24
| | | | | | | | | | | Otherwise the 'state fixup' in the receiver will change to Unconnected, but the receiver will terminate itself, and any attempt at 'down'ing that drbd later will block forever. see also Bugz. #259 Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>
* fix in-kernel configuration serializationLars Ellenberg2009-11-24
| | | | | | | | | this is uncritical, as we still also serialize in userland, but to correctly serialize on the CONFIG_PENDING bit, it must be wait_event(state_wait, \!test_and_set_bit) Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>

* Do not deadlock in drbd_disconnect() [bugz 258]Philipp Reisner2009-11-04
| | | | | | | | | | | | | | | | When there are many blocks on the fly (ua), and the AL gets into "starving" mode (random IO, scattered all over the device), and the connections gets interrupted, the receiver thread deadlocks in the drbd_disconnect() code path. Affected are only nodes in Primary role. The bug triggers most likely on system that mirror over "long distances" Regression introduced shortly before 8.3.3 with git commit 31e0f1250f174ac1ee317f360943a0159e19edc8 Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>
* drbdsetup X resume-io should be usable to resume IO [Bugz 256]Philipp Reisner2009-11-04
| | | | | | | | When IO gets frozen due to a broken fence-peer script, the user should be able to thaw IO by the resume-io command. Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>
* drbd: fix check for too large lower level deviceLars Ellenberg2009-11-04
| | | | | | | | | | To check wether we are truncating a very large device due to limited meta data space, we need to check the ll_dev size. Also improve the printk to suggest "flexible" or "internal". Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>
