Hello, I have IBM Storwize V3700 storage, connected to 2 IBM x3550 M4 servers via fiber channel. The servers are with QLogic ISP2532-based 8Gb Fibre Channel to PCI Express HBA cards and run Centos 5.10 When I export a volume to the servers, each of them sees the volume twice, i.e /dev/sdb and /dev/sdc, with the same size. Previously I have installed many systems with IBM DS3500 series of

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 to know what

Hi all, I was wondering if anyone might be able to speak about using IBM's GPFS filesystem as a means of storing virtual guests in a clustered environment with CentOS as the nodes and KVM as the hypervisor? I'm looking at using IBM's TSM software for archiving data from disk to tape. This requires buying a license for GPFS which is used in conjunction with TSM but can also be used

Hi all, I have two Cent5.6 systems running KVM in a clustered configuration with Cent5.6 guests. Ntpd is running on both hosts and all guests. When the guest is booted onto either of the hosts, time stays synced. When I do a live migration to the other host, the time on the guest starts going haywire, fast-forwarding into the future at a steady rate. After digging around, this may be related

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 site, too. Many

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 and will ext3 not allow for data integrity with multiple apache hosts

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

Hi all, A recent update to CentOS 5.9 has broken my cluster's ability to fence nodes. I have two Dell's which are both fenced via their DRAC6 cards. The current configuration in cluster.conf for the fencing devices is: <fencedevice agent="fence_drac5" cmd_prompt="admin1-&gt;" ipaddr="192.168.251.11" login="fencer" name="ms1-drac"

Hello, suppose I want to use a special configuration for my IBM/1814 storage array luns, then I put something like this in multipath.conf devices { device { vendor "IBM" product "^1814" product_blacklist "Universal Xport" path_grouping_policy "group_by_prio" path_checker

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....), so we decided to create a whole bunch of

Greetings ocfs2 folks, A client is experiencing some random deadlock issues within a cluster, wondering if anyone can point us in the right direction. The iSCSI connection seemed to have dropped on one node briefly, ultimately several hours later landing us in a complete deadlock scenario where multiple nodes (Node 7 and Node 8) had to be panic'd (by hand - they didn't ever panic on

Hi all, I''ve been trying to install Windows Server 2008 R2 under Xen 3.1 on Red Hat, but it keeps blue screening after the first reboot during the install. It seems to only affect 2008 R2. Windows Server 2008 installs fine, rebooting a couple of times along the way. With R2, it will go through the initial unpack and install, and then it reboots. I''m installing it

Hi list, I had setup my xen box with bond in active-backup mode. I had install open-iscsi as initiator to attach an external iscsi san to my box but open-iscsi didn''t work.

Hi all, I have the strangest problem on one of our backup server. iscsi doesn't start at all, and gives the following error: [root at 2U-NAS ~]# /etc/init.d/iscsi status iscsid is stopped [root at 2U-NAS ~]# /etc/init.d/iscsi start iscsid is stopped Starting iSCSI daemon: Unable to create pid file: /var/run/brcm_iscsiuio.pid [FAILED] Setting up iSCSI targets: iscsiadm: No records

I've got a CentOS 6 machine that's slated to go into production providing some web and development-repository services. Part of the environment is gitweb, which works as expected with one glitch: SELinux doesn't allow gitweb.cgi to query sssd to display who owns the repositories. The audit log entries are pretty straightforward, e.g., type=AVC msg=audit(XXXXXXXXXXXX): avc:
