When removing a volume/device we need to switch the connection status of the peer back into WFReportParams. Before this fix it was left in Connected state. That means that the peer device continued to inform us about state changes, etc... But we deleted that minor -> protocol error. Signed-off-by:

Detection of unclean shutdown has moved into user space. The kernel code will, whenever it updates the meta data, mark it as "unclean", and will refuse to attach to such unclean meta data. "drbdadm up" now schedules "drbdmeta apply-al", which will apply the activity log to the bitmap, and/or reinitialize it, if necessary, as well as set a "clean" indicator flag. This moves a bit code out of kernel space. As a side effect, it also prevents some 8.3 module from accidentally ignoring the 8.4 style activity log, if someone should downgrade, whether on purpose, or accidentally because he changed kernel versions without providing an 8.4 for the new kernel, and the new kernel comes with in-tree 8.3.

* drbd-8.3: documentation: Documented detach's --force and disk's --disk-timeout drbd: Implemented the disk-timeout option drbd: Force flag for the detach operation drbd: Allow new IOs while the local disk in in FAILED state drbd: Bitmap IO functions can not return prematurely if the disk breaks drbd: Added a kref to bm_aio_ctx drbd: Hold a reference to ldev while doing meta-data IO drbd: Keep a reference to the bio until the completion handler finished drbd: Implemented wait_until_done_or_disk_failure() drbd: Replaced md_io_mutex by an atomic: md_io_in_use drbd: moved md_io into mdev drbd: Immediately allow completion of IOs, that wait for IO completions on a failed disk drbd: Keep a reference to barrier acked requests Signed-off-by:

Regression introduced with 8.3.11 commit: drbd: Take a more conservative approach when deciding max_bio_size Never ever tell an older drbd, that we support more than 32KiB in a single data request (packet). Never believe an older drbd, that is supports more than 32KiB in a single data request (packet) Signed-off-by:

* commit 'ae57a0a': drbd: Only print sanitize state's warnings, if the state change happens drbd: we should write meta data updates with FLUSH FUA drbd: fix limit define, we support 1 PiByte now drbd: fix log message argument order drbd: Typo in user-visible message. drbd: Make "(rcv|snd)buf-size" and "ping-timeout" available for the proxy, too. drbd: Allow keywords to be used in multiple config sections. drbd: fix typos in comments.

Allow up to 300 centi-seconds to be configured for the "ping timeout". There may be setups where heavy congestion, huge buffers, and asymmetric bandwidth limitations may need a "huge" ping-timeout as work-around for "spurious connection loss" problems. Signed-off-by:

Fix warnings of the following nature in the drbd header: In file included from drivers/block/drbd/drbd_bitmap.c:32: drivers/block/drbd/drbd_int.h: In function 'drbd_get_syncer_progress': drivers/block/drbd/drbd_int.h:2234: warning: comparison is always false due to limited range of data where mdev->rs_total (an unsigned long) is being compared to 1ULL << 32, which is always false on a 32-bit machine.

drbdadm already has a --dry-run option, so this option cannot directly be passed through to drbdsetup. Rename the drbdsetup option to resolve this conflict. For backward compatibility, make --dry-run an alias of --tentative. Signed-off-by:

Before mainline commit ea5693cc (v2.6.29-rc1), empty nested netlink attributes were not allowed. Fix that by leaving out nested attributes if they are empty and by allowing the top-level attributes to be missing. Signed-off-by:

We need to remove the flag before checking for valid types. Signed-off-by:

Andreas Gruenbacher authored
Make it more clear in the flag names which flags are internal to drbd, and which are not. The check for mandatory attributes is the only extension visible at the netlink layer. Attributes with this flag set would look like unknown attributes to some kernel versions. The netlink layer would ignore them and also skip consistency checks on the attribute type and legth. To avoid this, we check for mandatory attributes first, remove the mandatory flag, and then process the attributes normally. Signed-off-by:

Since we need to hold that mutex anyways to make sure the peer gets that change in the right position in the data stream, it makes a lot of sense to use the same mutex to ensure existence of the tfm. Signed-off-by:

The 32-bit resync_after netlink field takes a device minor number as parameter, which is no longer limited to 255. We cannot statically verify which device numbers are valid, so set the ummer limit to the highest possible signed 32-bit integer. Signed-off-by:
