samba4 + drbd + ctdb + failover
Hi
We've got drbd going between 2 nodes:)
ATM there is un-partitioned space on each node but (we think) they are
syncing OK. It looks as though it has synced the whole partition (2GB)
from the primary node 1 to the other node:

OCZ Vertex3 SSD and LSI 9211-8i (mpt2sas)
I have a couple development servers running centos 6.3 64bit that have
LSI 9211-8i SAS2 controllers connected to a SAS2 backplane. these
work fine with SATA hard disks (populated with a bunch of 3TB SATA
drives)...
I'm trying to install a OCZ Vertex3 SSD on each of the two servers to do
some ssd caching tests... system sees the drive, so I do the following...

DRBD on a xen host: crash on high I/O
Hello,
I have a couple of Dell 2950 III, both of them with CentOS 5.3, Xen,
drbd 8.2 and cluster suite.
Hardware: 32DB RAM, RAID 5 with 6 SAS disks (one hot spare) on a PERC/6
controller.
I configured DRBD to use the main network interfaces (bnx2 driver), with
bonding and crossover cables to have a direct link.
The normal network traffic uses two different network cards.
There are two DRBD

ssd quandry
On a CentOS 6 64bit system, I added a couple prototype SAS SSDs on a HP
P411 raid controller (I believe this is a rebranded LSI megaraid with HP
firmware) and am trying to format them for best random IO performance
with something like postgresql.
so, I used the raid command tool to build a raid0 with 2 SAS SSDs

Node Recovery locks I/O in two-node OCFS2 cluster (DRBD 8.3.8 / Ubuntu 10.10)
I am running a two-node web cluster on OCFS2 via DRBD Primary/Primary
(v8.3.8) and Pacemaker. Everything seems to be working great, except during
testing of hard-boot scenarios.
Whenever I hard-boot one of the nodes, the other node is successfully fenced
and marked ?Outdated?

tcpdump?
Did the latest Centos4.x kernel break the ability to tcpdump with any
amount of traffic? Machines that used to be able to keep up now show a
few packets and stop - if you hit ^C they take a minute or so to do
anything, then show something like:
54 packets captured
18188 packets received by filter
18070 packets dropped by kernel
Before recent updates I almost never saw packets 'dropped

xen+drbd Question
Hi list,
I installed two new servers to be our virtualization HA. This servers
have CentOS 5.2, Xen 3.0.3, Drbd 8.2.6. The setup is ok, lvm drbd
resources sincronizing, Guest VM running without any problem.
My only doubt is that I can only use drbd resources inside guest vms
when I specify the disk resource in vms config like this:
disk = ['phy:/dev/VolGroup00/vappprtem01,hda,w' ]
