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

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

Hi, How do I setup multiple password protected iSCSI targets on Linux? I know that mounting a password protected iSCSI target requires modify these records with the appropriate values: node.session.auth.username = My_ISCSI_USR_NAME node.session.auth.password = MyPassword discovery.sendtargets.auth.username = My_ISCSI_USR_NAME discovery.sendtargets.auth.password = MyPassword But, now I need

Hi, I'd like to know what would be the best way to remove an iscsi lvm storage from a server. (removing all reference to that storage etc.) The storage in question will be reset and reformated and used on a different server; so no LVM export is needed. Do I have to do lvremove ..., vgremove ..., pvremove ... and do an iscsiadm -m node -T ... -p ... -u and iscsiadm -m node -o delete -T ...

Hi, I'm trying to disconnect some iSCSI targets, but can't seem to.

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

Hi all, After finding multiples answers to this question via google, but without making it work on my servers. Has anybody iSCSI Offload working on a Dell Server with Broadcom NICs ? My environment: I'm running CentOS 5.6 CR, on a Dell PowerEdge R710 with Broadcom Corporation NetXtreme II BCM5709 conecting to an EMC CX4-120 SAN, via 2x Cisco 2960G-24TC-L switches. It's working

Hello everyone, I have recently installed libvirt 1.0.0 and am having a problem with my iSCSI storage pool's autostarting. They are just going to an inactive state right after a reboot of the host. However once the startup is complete I can manually start the pool without problem. I am getting the following errors in the libvirtd.log file but they don't really give me much as to what

Hi! I'm new to libvirt and face problems connecting to an iSCSI target. What I intend to do is to connect libvirt (I tried virt-manager and virsh) to an iSCSI target and then boot from the LUNs which contain the VMs. I followed the documentation¹ but got stuck at section 12.1.5.4.3. 1) virsh pool-define-as \ --name foo \ --type iscsi

Hello, I have a LVM with 2 ISCSI disk mounted. The partition started presents problem such " i/o error". I unmounted the device, and restarted target server in scsi, wich as having some problems. After that i mapped iscsi and trying to mount partition again but: When i run the pvdisplay i get the following erro: read failed after 0 of 4096 at 0: Input/output error And cannot mount

Hi, I increased the size of one of the LUNs and on CentOS 5.4 if I restart iscsi (`service iscsi restart`) I'll see the the new size but this will disconnect all other LUNs. I'm hoping that there is isciadm or some other command that will force iscsi to rediscover the LUNs but I can't seem to be able to come up with one. Resize2fs says that there is nothing to be done. I'm

I am fairly new to ISCSI and SAN technology but having recently invested in the technology I am trying to find out exactly what can and can not be manipulated, filesystem wise, without requiring a reboot. I am using the inbuilt software ISCSI initiator and multipathing in CentOS 5.1. My steps so far. Create 10GB volume on SAN # iscsiadm -m session -R # fdisk /dev/mapper/mpath0 # kpartx -a

Hi, Is it possible to discover iSCSI targets using libvirt API..? OR is it possible to get the similar results of below commands using libvirtAPI..? iscsiadm --mode discovery --type sendtargets --portal server1.example.com sudo iscsiadm -m discovery -t st -p 192.168.0.10 Regards Sijo

I am trying to install Oracle RAC in a two node cluster for testing purposes, so performance is not something that concerns me. I just want to go through the process all the way to creating a database. I have all the prerequisites except the shared storage and thought I'd give this a try. I'm running: - CentOS 5.3 kernel 2.6.18-164.el5 - iscsitarget-1.4.18-1 -
