* The max of minor_count is 255 * In drbdadm count the number of minors, instead of finding the highest minor number * No longer us the magic in the init script Signed-off-by:

If we get into the C_BROKEN_PIPE cstate once, the state engine set the thi->t_state of the receiver thread to restarting. But with the while loop in drbdd_init() a new connection gets established. After the call into drbdd() returns immediately since the thi->t_state is not RUNNING. The restart of drbd_init() then resets thi->t_state to RUNNING. I.e. after entering C_BROKEN_PIPE once, the next successful established connection gets wasted. The two parts of the fix: * Do not cause the thread to restart if we detect the issue with the sockets while we are in C_WF_CONNECTION. * Make sure that all actions that would have set us to C_BROKEN_PIPE happen before the state change to C_WF_REPORT_PARAMS.

The last data-integrity-alg fix made data integrity checking work when the algorithm was changed for an established connection, but the common case of configuring the algorithm before connecting was still broken. Fix that. Signed-off-by:

Since we now apply the AL in user space onto the bitmap, the AL is not active for the requests we want to reply. For that a al_write_transaction() that might be called from worker context became necessary. Signed-off-by:

In case we can not find out why the request takes too long (happens e.g. when IO got suspended on DRBD level). rearm the timer with a reasonable value. Signed-off-by:

The minor_count module/kernel parameter serves to scale the size of drbd's internal memory pool, but it is no longer a limit for the number of minors or the minor number. (Minor numbers can be arbitrarily high within the allowed limit of 2^20.) Signed-off-by:

The maximum minor device number allowed by the kernel is (1<<20 - 1). Reject device numbers higher than that to earlier catch possible errors. Signed-off-by:

* Enabled the resync controller, with a fill target of 50Kib. That gives reasonable resync speeds without tuning. A much better default than the 250KiB/s fixed. * Enable bitmap compression. It is save to use, and most people have more CPU power than network bandwidth. * ko-count of 7: Abort a connection if the peer fails to process a write request within 42 seconds. * al-extents of 1237: ~5 GiB seems to be a much more sane default these days.

Currently it is legal (though unusual) to create and connect a resource, before adding in all necessary volumes. We should include the network configuration details, even if we don't have a single volume (yet). Signed-off-by:

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.

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:
