CentOS and Dell MD3200i / MD3220i iSCSI w/ multipath
We've been wrestling with this for ... rather longer than I'd care to admit.
Host / initiator systems are a number of real and virtualized CentOS 5.5
boxes. Storage arrays / targets are Dell MD3220i storage arrays.
CentOS is not a Dell-supported configuration, and we've had little helpful
advice from Dell. There's been some amount of FUD in that Dell don't seem

Pool, iSCSI and guest start
-----BEGIN PGP SIGNED MESSAGE-----

Hi,
Former user of Xen and newbie in kvm/qemu/libvirt stuff, I give it a try
on my network ;-)
I need to run a VM with iSCSI target attached.
I did it this way :

Dell Equallogic
Hi List,
Does anyone here use Dell Equallogic IP SAN? If so, do you have any
immediate high points / low points you wouldn't mind discussing on- or
off-list ?
Thanks.

ZFS with Equallogic storage
I''m planning on setting up an NFS server for our ESXi hosts and plan on using a virtualized Solaris or Nexenta host to serve ZFS over NFS.
The storage I have available is provided by Equallogic boxes over 10Gbe iSCSI.
I am trying to figure out the best way to provide both performance and resiliency given the Equallogic provides the redundancy.
Since I am hoping to provide a 2TB

Moving zfs to an iscsci equallogic LUN
We have a Mirror setup in ZFS that''s 73GB (two internal disks on a sun fire v440). We currently are going to attach this system to an Equallogic Box, and will attach an ISCSCI LUN from the Equallogic box to the v440 of about 200gb. The Equallogic Box is configured as a Hardware Raid 50 (two hot spares for redundancy).
My question is what''s the best approach to moving the ZFS

Support XCP 1.0 for adapter Dell EqualLogic PS Series SAN arrays on Xencenter
Anyone here using the XCP 1.0 Storage EqualLogic has the dell? In
Citrix XenServer Xencerter appears to integration, but in XenCenter
not with XCP. I read that the drivers were removed. No way around
installing the drivers again?

iscsi storage, LACP or Multipathing | Migration or rebuild?
Hi,
I do have one iscsi storage with 4 GBit nics of which currently only one
is configured with an ip and which is in productive use by one cent os
6.3 server.
Doing some research brought me to the idea to use some nic bonding or
multipathing for that storage, but multipathing I did about four or five
years ago only once :)

iscsi storage and multipathing
First, I am new to Xen.... So forgive me if I am overlooking something. Here
is my situation, I have multiple dom0''s that are part of an ocfs2 cluster.
The dom0''s mount multiple volumes (/home, /app, /images) from an ISCSI
storage array. Their eth2/eth3 network interfaces are attached to a private
storage network. They are not part of Xen''s network bridge and have

Windows DomU on NAS
Hello,
I''d like to be able to create a windows DomU which is to be stored on
a NAS (Equallogic) device. I was wondering if anyone has any best
practices on how to do this? Is there a way to extend the DomU C drive
once you create the initial device, etc? Any suggestions would be great.
I have already tried this by just using a phy:/dev/path-to-iscsi-mount-
point and it appears to

iscsi of a SAN on a DomU
Hi,
i have a debian Etch x86_64 with a xen 3.1 on a kernel 2.6.18-xen.
I have some DomU with Debian Etch.

ZFS and multipath with iSCSI
We''re currently designing a ZFS fileserver environment with iSCSI based
storage (for failover, cost, ease of expansion, and so on). As part of
this we would like to use multipathing for extra reliability, and I am
not sure how we want to configure it.
Our iSCSI backend only supports multiple sessions per target, not
multiple connections per session (and my understanding is that the

Who does snapshots other than Network Appliance?
Having snapshot technology is great. Who else supports it?

sdc1 without the sdc
So I'm working with the iSCSI Initiator and an EqualLogic SAN. I'm
not sure when this might have happened, but it appears that the
/dev/sdc device is missing, yet the /dev/sdc1 partition exists AND is
mountable. Is there a method to re-create the /dev/sdc device? I
cannot dd or fdisk it, obviously, but I can mount the /dev/sdc1
partition and it works just fine. Not having the /dev/sdc

Highly Performance and Availability
Hello everyone,
I am currently running Dovecot as a high performance solution to a particular
kind of problem. My userbase is small, but it murders email servers. The volume
is moderate, but message retention requirements are stringent, to put it nicely.
Many users receive a high volume of email traffic, but want to keep every
message, and *search* them. This produces mail accounts up to

ISCSI SAN suggestion
Sorry for the off-topic question but I need advice on a buying a ISCSI
SAN for 4-6 servers running CentOS 4.4 .The main purpose for the SAN
is to store email accounts (that will be accessed by imap - dovecot)
and other documents. Minimal redundancy is required (e.g. dual power
supplies, battery backed write cache or mirrored controllers) and
price for a 2 TB configuration should be under $ 10000.

OCFS and multipathing
I've got my RAC cluster running pretty smoothly now (thanks again for all
the help so far), but I only have single connections between the servers and
the RAID array. The servers each have two Qlogic HBAs, and I'd like to find
out if there's any reasonable way to implement multipathing.
The platform is RHEL 3, and Red Hat's knowledgebase indicates that they

Need SAN suggestion
Hello,
It is not total off-topic since almost all connected servers will be RHEL
and CentOS. :)
We are considering to purchase new storage system. The most probably we
will be choosing between HP (EVA6000), EMC (CX3-20C) and Hitachi (similar
model).
iSCSI connection is also required.
What are your experienced with listed systems? What to avoid? What ot
expect?

Hi
How can i enable this feature because:
Running /opt/xensource/libexec/mpp-rdac --enable it says:
No module mppUpper found for kernel 2.6.32.12-0.7.1.xs1.0.0.298.170582xen,

disk device lvm iscsi questions ....
Hi,
I have an iscsistorage which I attached to a new centos 6.3 server. I
added logic volumes as usual, the block devices (sdb & sdc) showed up in
dmesg; I can mount and access the stored files.
Now we did an firmware software update to that storage (while
unmounted/detached from the fileserver) and after reboot of the storage
and reatache the iscsi nodes I do get new devices. (sdd &
