Out of haste I decided for the first time not to pull down and compile iet to export a single volume to a windows machine so I just used tgtd. Well, much more time later than otherwise would be the case had I used iet, when I mount the volume on the windows ini, it can't find and install a driver? WTF? This have anything to do with the tgtd being a tech preview:) Anybody seen this b4? jlc

...is true active/active MPIO utilizing the dm driver to combine LUN 1 from both host1 and host2 as a single /dev/dm-0 device in active/active mode. This would allow me to multipath across multiple fabrics, develop true high availability and increase my throughput significantly. Any idea of an iscsi tgtd that supports this? As far as I can tell, none do (that I can find). I know some proprietary vendors have this type of functionality, which may or may not be using iSCSI code (but that's a whole set of arguments for later..). Ultimately, my goal is this. I want to take my existing Ceph cluste...

...arge amount the performance of the equivalent file systems built with such packages as MooseFS and GlusterFS: I get about 350 MB/sec write speed through the file system, and up to 800 MB/sec read. I have built something like this, and by performing tests such as sending a SIGKILL to one of the tgtd's, I have been unable to kill access to the file system. Obviously one has to manually intervene on the return of the tgtd in order to fail/hot-remove/hot-add the relevent target(s) to the md device. Presumably this will be made easier by using persistent device names for the targets on S....

Hi, I was wondering if anyone has successfully configured two lsi/3ware 9750-4i series controllers for multipathing under CentOS 5.7 x86_64? I've tried some basic setups with both multibus and failover settings, and had repeatable filesystem corruption over a iscsi(tgtd) or nfs3 connection. Any ideas? Vahan

I always used IET on CentOS but I have a quick server to setup to backup some VM's, then migrate to DAS on another server and the easiest way for me will be to accomplish this via iSCSI vmfs stores. I figured I would just use the ini that ships with CentOS but have never used it against ESX, anyone do this and have experiences they care to share? Should it be trivial or are there any non

Hello fellow sysadmins! I've assembled a whitebox system with a SuperMicro motherboard, case, 8GB of memory and a single quad core Xeon processor. I have two 9650SE-8LPML cards (8 ports each) in each server with 12 1TB SATA drives total. Three drives per "lane" on each card. CentOS 5.2 x86_64. I'm looking for advice on tuning this thing for performance. Especially for the

...d target driver support in Linux SCSI mid layer. It has been included in the -mm tree. This patchset includes a modified version of tgt code. - Instructions This patchset is against cset 10426:840f33e54054. `make world && make install` should work. The user-space daemon code is at tools/tgtd directory. Configure your VM config file to use the SCSI drivers. If you like to export /dev/sdb1 as a logical unit to a VM, add the following line: scsi = [ ''disk:/dev/sdb1,w'' ] You must run the user-space daemon before starting domainUs (otherwise Domain0 crashes). /usr/sbin...

Has anyone succesfully setup, and used CentOS as an iSCSI server? I'm trying to setup a server with 4x500GB HDD's, setup in RAID 10 to act as an iSCSI server for a virtualization project, but I can't find a decent howto on how to setup an iSCSI server using CentOS. I would like to setup something like Openfiler, but we also need todo some other stuff that OpenFiler doesn't

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

Hi all, I have setup a centos5.2 server (full updated) to serve iscsi disks using scsi-target-utils package. This server has two network adapters, one for remote administration and another to serve iscsi disk. How can I bind iscsi target service to only one ip address?? Many thanks. -- CL Martinez carlopmart {at} gmail {d0t} com

Hi, I'm starting to experiment with iscsi based volumes and while this works fine so far I ran into a problem. When I add a LUN to a target and refresh tgtd all i/o to that target seems to hang for five seconds. This is obviously less than ideal if the plan is to use the target for lots of guests. There is also the possibility to create one target with one LUN for each guest disk but that sounds like a management nightmare and the libvirt pool funct...

Hi all, I would like to know if I could share some space on on of my servers, to another server(s) using the iSCSI protocal? I can see that CentOS can connect to an iSCSI server, but can it act as a iSCSI server? Is so, does anyone have some good HOWTO / tutorials / docs on how to set it up? I'm running CentOS 5.2 -- Kind Regards Rudi Ahlers
