drbd: introduce stop-sector to online verify

2012-11-09T13:05:32Z

We now can schedule only a specific range of sectors for online verify, or interrupt a running verify without interrupting the connection. Had to bump the protocol version differently, we are now 101. Added verify_can_do_stop_sector() { protocol >= 97 && protocol != 100; } Also, the return value convention for worker callbacks has changed, we returned "true/false" for "keep the connection up" in 8.3, we return 0 for success and <= for failure in 8.4. Affected: receive_state() Signed-off-by: Philipp Reisner Signed-off-by: Lars Ellenberg

drbd: New disk option al-updates

2012-11-08T15:58:31Z

By disabling al-updates one might increase performace. The price for that is that in case a crashed primary (that had al-updates disabled) is reintegraded, it will receive a full-resync instead of a bitmap based resync. Signed-off-by: Philipp Reisner Signed-off-by: Lars Ellenberg

drbd: Load balancing of read requests

drbd: detach from frozen backing device

2012-11-08T15:57:50Z

* 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: Philipp Reisner Signed-off-by: Lars Ellenberg

drbd: Rename --dry-run to --tentative

2012-11-08T15:57:47Z

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: Philipp Reisner Signed-off-by: Lars Ellenberg

drbd: Also need to check for DRBD_GENLA_F_MANDATORY flags before nla_find_nested()

2012-11-08T15:57:45Z

This is done by introducing drbd_nla_find_nested() which handles the flag before calling nla_find_nested(). Signed-off-by: Philipp Reisner Signed-off-by: Lars Ellenberg

drbd: Make drbd's use of netlink attribute flags less confusing

2012-11-08T15:55:55Z

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: Philipp Reisner Signed-off-by: Lars Ellenberg
