ZFS in front of MD3000i
We''re setting up ZFS in front of an MD3000i (and attached MD1000 expansion trays). The rule of thumb is to let ZFS manage all of the disks, so we wanted to expose each MD3000i spindle via a JBOD mode of some sort. Unfortunately, it doesn''t look like the MD3000i this (though this[1] post seems to reference an Enhanced JBOD mode.......

creating ZFS mirror over iSCSI between to DELL MD3000i arrays
Hi, I''ve looked at ZFS for a while now and i''m wondering if it''s possible on a server create a ZFS mirror between two different iSCSI targets (two MD3000i located in two different server rooms). Or is it any setup that you guys recommend for maximal data protection. Thanks, /Thom This message posted from opensolaris.org

iscsi and the last mile...
I have a new Dell PowerEdge 2950 running CentOS 5.0 out-of-box and a Dell MD3000i. I am new to iscsi and, with google and included documentation, am having a heck of a time trying to get the RAID volumes I have created on the 3000i to be seen by the OS as usuable drives. I have printed out SMcli and iscsiadm documentation. I have asked on the linux-poweredge at dell.com...

iSCSI / GFS shared web server file system
We currently have a MD3000i with an iSCSI LUN shared out to our apache web server. We are going to add another apache web server into the mix using LVS to load balance, however, I am curious how well iSCSI handles file locking and data integrity. I have the iSCSI partition formatted as ext3. Is my setup totally flawed an...

CentOS and Dell MD3200i / MD3220i iSCSI w/ multipath
...error messages on the initator at target login. These appear to be benign, and web research suggests it's the result of a driver configuration issue in trying to send instructions to a http://comments.gmane.org/gmane.linux.iscsi.open-iscsi/5970 http://bit.ly/gguLl7 MD3000i boxes have 1 controller that can execute IO and one that cannot execute READ/WRITE IO until a special command is sent. In older kernels, layers like the partition scanning and udev and hal would send down IO to those disabled paths and we would see IO errors like in...

iscsi multipath fails
Hi all, I have a Dell server running cent 5.6, new install, connecting to an IBM DS3500. I have configured iscsi connections using iscsid and can log into the targets on the IBM. I can also mount the LUNs when accessing them from their active controller path. When I throw multipath into the mix, it fails completely. Multipath is working, when I run multipath -ll it shows me the correct active

GFS + Restarting iptables
Dear List, I have one last little problem with setting up an cluster. My gfs Mount will hang as soon as I do an iptables restart on one of the nodes.. First, let me describe my setup: - 4 nodes, all running an updated Centos 5.2 installation - 1 Dell MD3000i ISCSI SAN - All nodes are connected by Dell?s Supplied RDAC driver Everything is running stable when the cluster is started (tested for a week or so), when I did some last changes in my firewall and did an iptables restart it all went down after a while. I reproduced the issue now several ti...
