similar to: 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

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

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

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

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 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

I''m posting here as this seems to be a zfs issue. We also have an open ticket with Sun support and I''ve heard another large sun customer also is reporting this as an issue. Basic Problem: Create a zfs file system and set shareiscsi to on. On a vmware esx server discover that iscsi target. It shows up as 249 luns. When attempting to then add the storage esx server eventually

Hi there. I''m looking at moving my home server to ZFS and adding a second for backup purposes. In the process of researching ZFS I noticed iSCSI. I''m thinking of creating a zvol, share it with iSCSI and use it with my Mac(s). In this scenario, the fs would obviously have to be HFS+. Now, my question is: How would I go about replicating this non-native FS to the backup server?

Hi, I''m trying to track down an error with a 64bit x86 OpenSolaris 2009.06 ZFS shared via iSCSI and an Ubuntu 10.04 client. The client can successfully log in, but no device node appears. I captured a session with wireshark. When the client attempts a "SCSI: Inquiry LUN: 0x00", OpenSolaris sends a "SCSI Response (Check Condition) LUN:0x00" that contains the

I don''t know if VSS has this capability, but essentially if it can temporarily quiesce a device like a data base does for "warm standby" then a snapshot should work. This would be a very simple Windows side script/batch: 1) Q-Disk 2) Remote trigger snapshot 3) Un Q-Disk I have no idea where to even begin researching VSS unfortunately...

Hi Folks, Just wondering if anyone had any tips for trying to install a NV 94 DomU with ZFS root to an iSCSI Target? The iSCSI Target happens to be a NV 94 system with ZVOLs exported as the Targets, but I wouldn''t think that would matter. I tried this last week and the install seemed to complete fine, but when the DomU attempted to reboot after install, I received a message to the

Is there any way to increase the ZFS performance? -- This message posted from opensolaris.org

Hi friends, i have a problem. I have a file server which initiates large volumes with iscsi initiator. Problem is, zfs side it shows non aviable space, but i am %100 sure there is at least, 5 TB space. Problem is, because zfs pool shows as 0 aviable all iscsi connection got lost and all sharing setup is gone and need restart to fix. all time till today i keep delete snapshots and make it alive

I have set up an iSCSI ZFS target that seems to connect properly from the Microsoft Windows initiator in that I can see the volume in MMC Disk Management. When I shift over to Mac OS X Tiger with globalSAN iSCSI, I am able to set up the Targets with the target name shown by `iscsitadm list target` and when I actually connect or "Log On" I see that one connection exists on the Solaris

Hey all, I''m setting up a ZFS based fileserver to use both as a shared network drive and separately to have an iSCSI target to be used as the "Hard disk" of a windows based VM runninf on another machine. I''ve built the machine, installed the OS, created the RAIDZ pool and now have a couple of questions (I''m pretty much new to Solaris by the way but have been

I am using a Solaris + ZFS environment to export a iSCSI block layer device and use the snapshot facility to take a snapshot of the ZFS volume. Is there an existing Volume Shadow Copy (VSS) implementation on Windows for this environment? Thanks S Joshi -------------- next part -------------- An HTML attachment was scrubbed... URL:

I''ve been experimenting with a two system setup in snv_134 where each system exports a zvol via COMSTAR iSCSI. One system imports both its own zvol and the one from the other system and puts them together in a ZFS mirror. I manually faulted the zvol on one system by physically removing some drives. What I expect to happen is that ZFS will fault the zvol pool and the iSCSI stack will
