Subject: [PATCH 00/30] DRBD updates
Date: Mon, 13 Jun 2016 16:08:48 +0200 [thread overview]
Message-ID: <1465826958-19398-1-git-send-email-philipp.reisner@linbit.com> (raw)
Hi Jens,
I have sent this already on April 25, I guess it was too late in the cycle
at that time. Apart from the usual maintenance and bug fixes this time comes
support for WRITE_SAME and lots of improvements for DISCARD.
At that time we had a discussion about (1) the all_zero() heuristic introduced
with [PATCH 04/30] drbd: Implement handling of thinly provisioned storage...
not being efficient, and about the (2) rs-discard-granularity configuration
parameter.
Regarding (1): I intend to work on block-devices being able to export their
allocation map by either FIEMAP or SEEK_HOLE/SEEK_DATA or both for the next
cycle. The I will change DRBD to use that as well.
Regarding (2): We need to announce the discard granularity when we create the
device/minor. At might it might be that there is no connection to the peer
node. So we are left with information about the discard granularity of the
local backing device only. Therefore we decided to delegate it to the
user/admin to provide the discard granularity for the resync process.
Please add it to your for-4.8/drivers branch.
Thanks!
Fabian Frederick (1):
drbd: code cleanups without semantic changes
Lars Ellenberg (24):
drbd: bitmap bulk IO: do not always suspend IO
drbd: change bitmap write-out when leaving resync states
drbd: adjust assert in w_bitmap_io to account for
BM_LOCKED_CHANGE_ALLOWED
drbd: fix regression: protocol A sometimes synchronous, C sometimes
double-latency
drbd: fix for truncated minor number in callback command line
drbd: allow parallel flushes for multi-volume resources
drbd: when receiving P_TRIM, zero-out partial unaligned chunks
drbd: possibly disable discard support, if backend has
discard_zeroes_data=0
drbd: zero-out partial unaligned discards on local backend
drbd: allow larger max_discard_sectors
drbd: finish resync on sync source only by notification from sync
target
drbd: introduce unfence-peer handler
drbd: don't forget error completion when "unsuspending" IO
drbd: if there is no good data accessible, writes should be IO errors
drbd: only restart frozen disk io when D_UP_TO_DATE
drbd: discard_zeroes_if_aligned allows "thin" resync for
discard_zeroes_data=0
drbd: report sizes if rejecting too small peer disk
drbd: introduce WRITE_SAME support
drbd: sync_handshake: handle identical uuids with current (frozen)
Primary
drbd: disallow promotion during resync handshake, avoid deadlock and
hard reset
drbd: bump current uuid when resuming IO with diskless peer
drbd: finally report ms, not jiffies, in log message
drbd: al_write_transaction: skip re-scanning of bitmap page pointer
array
drbd: correctly handle failed crypto_alloc_hash
Philipp Reisner (4):
drbd: Kill code duplication
drbd: Implement handling of thinly provisioned storage on resync
target nodes
drbd: Introduce new disk config option rs-discard-granularity
drbd: Create the protocol feature THIN_RESYNC
Roland Kammerer (1):
drbd: get rid of empty statement in is_valid_state
