OCFS2 + iscsi: another node is heartbeating in our slot (over scst)
Hi,
I'm building a cluster containing two nodes with seperate common storage
server.
On storage server i have volume with ocfs2 fs which is sharing this
volume via iscsi target.
When node connected to the target i can local mount volume on node and
using it.
Unfortunately. on storage server ocfs2 logged to dmesg:

One more follow on,
The combination of kernel.panic=60 and kernel.printk=7 4 1 7 seems to

Another node is heartbeating in our slot! errors with LUN removal/addition
Greetings,
Last night I manually unpresented and deleted a LUN (a SAN snapshot)
that was presented to one node in a four node RAC environment running
OCFS2 v1.4.1-1. The system then rebooted with the following error:

O2CB global heartbeat - hopefully final drop!
All,
This is hopefully the final drop of the patches for adding global heartbeat
to the o2cb stack.
The diff from the previous set is here:
http://oss.oracle.com/~smushran/global-hb-diff-2010-10-07
Implemented most of the suggestions provided by Joel and Wengang.
The most important one was to activate the feature only at the end,
Also, got mostly a clean run with checkpatch.pl.

[GIT PULL] ocfs2 changes for 2.6.37
Linus, et al,
Here are the ocfs2 changes for 2.6.37. There are three major

poor write performance or locking issues with ocfs2
Hello all,
I've got heavy troubles with my ocfs2 environment. Cluster filesystem worked fine for about 3-6 weeks after initial setup, but since 1 week performance issues occurs. I've already searched long time in google and on this mailing list but I wasn't able to found any solution. I've found a lot of posts with "same" problems but without the magic answer :-)

R-alpha: model.matrix misbehaves on two-sided formulas
I am using R for a graduate class on linear models that I teach. I
sent the class a sample transcript of explicit construction of the
model matrix and use of the QR decomposition. One of the members of
the class picked up on the fact that the model matrix was not what I
advertised that it should be when a two-sided formula is used. A
one-sided formula works properly. For example,

Filesystem too large...
I need to setup a 3.27TB ext3 filesystem using -i 1024 and -b 1024.
When I try to format this partition I get the "Filesystem too large."
error. Are there any plans to update these limits? are there any
patches already available that I can try out? Or am I just SOL here?

Xvd Problem
We recently added a disk to our Coraid SAN. We''ve used tons of
devices off of this SAN with Xen before, but this time we experienced
some weird behavior.
I configured a DomU to have the device directly offered as a disk
(i.e. ''phy/dev/etherd/e1.1,sdb1,rw''). When I tried to boot it, an
xvd process showed up as usual. However, it consumed 100% processor

[git patches] ocfs2 fixes
Hi Linus,
Here are some 2.6.20 fixes for ocfs2. The patch by Zhen Wei isn't
really a fix, but a very small amount of support for a feature which is
mostly implemented in ocfs2-tools. Considering it's just a single attribute
export via configfs, I'd say it's pretty safe to merge.

Cisco gateways and hairpinning
Hello:
Has anyone on this list had to configure hairpinning on a Cisco
gateway running IOS 12.2 or 12.3 and using a PRI for connectivity
to the PSTN? If so could you tell me how it is done? I'm told this
is the source of my call transfer problems and yet I cannot find
clear instructions for how the configuration is done.
Thanks,Steve

[PATCH -v2 0/3] jbd2 scalability patches
This version fixes three bugs in the 2nd patch of this series that
caused kernel BUG when the system was under race. We weren't accounting
with t_oustanding_credits correctly, and there were race conditions
caused by the fact the I had overlooked the fact that
__jbd2_log_wait_for_space() and jbd2_get_transaction() requires
j_state_lock to be write locked.
