The mm-of-the-moment snapshot 2016-08-02-15-53 has been uploaded to
http://www.ozlabs.org/~akpm/mmotm/
mmotm-readme.txt says
README for mm-of-the-moment:
http://www.ozlabs.org/~akpm/mmotm/
This is a snapshot of my -mm patch queue. Uploaded at random hopefully
more than once a week.
You will need quilt to apply these patches to the latest Linus release (4.x
or 4.x-rcY). The series file is in broken-out.tar.gz and is duplicated in
http://ozlabs.org/~akpm/mmotm/series
The file broken-out.tar.gz contains two datestamp files: .DATE and
.DATE-yyyy-mm-dd-hh-mm-ss. Both contain the string yyyy-mm-dd-hh-mm-ss,
followed by the base kernel version against which this patch series is to
be applied.
This tree is partially included in linux-next. To see which patches are
included in linux-next, consult the `series' file. Only the patches
within the #NEXT_PATCHES_START/#NEXT_PATCHES_END markers are included in
linux-next.
A git tree which contains the memory management portion of this tree is
maintained at git://git.kernel.org/pub/scm/linux/kernel/git/mhocko/mm.git
by Michal Hocko. It contains the patches which are between the
"#NEXT_PATCHES_START mm" and "#NEXT_PATCHES_END" markers, from the series
file, http://www.ozlabs.org/~akpm/mmotm/series.
A full copy of the full kernel tree with the linux-next and mmotm patches
already applied is available through git within an hour of the mmotm
release. Individual mmotm releases are tagged. The master branch always
points to the latest release, so it's constantly rebasing.
http://git.cmpxchg.org/cgit.cgi/linux-mmotm.git/
To develop on top of mmotm git:
$ git remote add mmotm git://git.kernel.org/pub/scm/linux/kernel/git/mhocko/mm.git
$ git remote update mmotm
$ git checkout -b topic mmotm/master
<make changes, commit>
$ git send-email mmotm/master.. [...]
To rebase a branch with older patches to a new mmotm release:
$ git remote update mmotm
$ git rebase --onto mmotm/master <topic base> topic
The directory http://www.ozlabs.org/~akpm/mmots/ (mm-of-the-second)
contains daily snapshots of the -mm tree. It is updated more frequently
than mmotm, and is untested.
A git copy of this tree is available at
http://git.cmpxchg.org/cgit.cgi/linux-mmots.git/
and use of this tree is similar to
http://git.cmpxchg.org/cgit.cgi/linux-mmotm.git/, described above.
This mmotm tree contains the following patches against 4.7:

-master-goes-down.patch
This one completely broke two node cluster use case: when one node dies,
the other one either eventually crashes (~4.14-rc4) or locks up (pre-4.14).

Are you sure?
Are you able to confirm that reverting this patch (ee8f7fcbe638b07e8)
and only this patch fixes up current mainline kernels?
Are you able to supply more info on the crashes and lockups so that the
ocfs2 developers can understand the failures?
Thanks.

Hi Andrew and Vitaly,
I do agree that patch ee8f7fcbe638 ("ocfs2/dlm: continue to purge
recovery lockres when recovery master goes down", 2016-08-02) introduced
an issue. It makes DLM recovery can't pick up a new master for an
existed lock resource whose owner died seconds ago.
But this patch truly solves another issue.
So I think we can't just revert this patch but to give a fix to it.
Thanks,
Changwei

I'm not saying we must revert the patch, I just stating it broke one of use cases :)
Here's a tad more diagnosis:
System is x86-64 Fedora 25 (I think) with 4.14-rc4.
Cluster config:
# cat /etc/ocfs2/cluster.conf
cluster:
node_count = 2
name = cyccfs
node:
number = 1
cluster = cyccfs
ip_port = 7777
ip_address = 192.168.122.93
name = node-A
node:
number = 2
cluster = cyccfs
ip_port = 7777
ip_address = 192.168.122.96
name = node-B
Test case (run on both nodes):
# cat ocfs
#!/bin/bash
modprobe ocfs2_stack_o2cb
modprobe ocfs2_dlmfs
SYSTEMCTL_SKIP_REDIRECT=1 service o2cb start
SYSTEMCTL_SKIP_REDIRECT=1 service ocfs2 start
mount /dev/sdd /ocfs
touch /ocfs/file
while true; do
dd if=/dev/urandom of=/ocfs/file bs=1 count=100 conv=notrunc oflag=append
dd if=/ocfs/file of=/dev/null bs=1
done
Then send hard reboot to either node - in this case it's A.
Please ignore inconsistent dmesg timestamps - cut&paste from multiple runs.
Node B runs, notices A passed away, loops with error -107 until A reappears, then currently used lock becomes unusable (file behind the lock too):
