Razique, thanks for sending
these along to me a little
while back. A couple that I
found were useful:</li>
<ul>
<li>KVM cache=writeback (a
little risky, but WAY
faster)</li>
<li>Gluster write-behind-window-size
(set to 4MB in our setup)</li>
<li>Gluster cache-size (ideal
values in our setup were
96MB-128MB)</li>

all,<br>
<br>
I have issue
with creating
shared storage
for Openstack.
Main idea is
to create 100%
redundant
shared storage
from two
servers (kind
of network
RAID from two
servers).<br>
I have two
identical
servers with
many disks
inside. What
solution can
any one
provide for
such schema? I
need shared
storage for
running VMs
(so live
migration can
work) and also
for
cinder-volumes.<br>
<br>
One solution
is to install
Linux on both
servers and
use DRBD +
OCFS2, any
comments on
this?<br>
Also I heard
about Quadstor
software and
it can create
network RAID
and present it
via iSCSI.<br>
<br>
Thanks.<br>
<br>
P.S. Glance
uses swift and
is setuped on
another
servers<br>
