REQUEST: How to configure Cloudmin to use ISCSI targets...

Hello, long time user of Webmin and Virtualmin. I personally think its the best control panel out there. I recently purchased a one year license on Cloudmin, so far very happy with the results.

In my previous experience with other virtual suites, such as Xen Server, Proxmox, or VMWare ESX/ESXi, I've had the ability to set up remote storage. However, I do not see this option in Cloudmin. After glossing over the forums, I've noticed that it is possible to setup ISCSI clients.

I was wondering if someone could point me in the right direction. Thanks for the great product.

Cloudmin can make use of LVM for storing disk images for virtual systems, and some users have made use of LVM's cluster support and iSCSI to share volume groups between multiple host systems. Cloudmin fully supports fast VM moves and failovers in this case ... however, it requires that you perform the iSCSI and LVM setup manually first.

Thanks for the prompt reply. If I understand you correctly, you are saying that LVM is something of an iscsi initiator? Is that correct? If so, could you kindly point me into the right direction for a tutorial?

To be honest, we don't have much personal experience with iSCSI and Cloudmin as all our test systems use local disk for storage. However, there is some documentation out there on the web about combining Xen and iSCSI - for example : http://www.performancemagic.com/iscsi-xen-howto/

This sounds like an area that Cloudmin needs better support for though, so I will add it to our roadmap.

Jamie, thank you for the link. I will further read up on that documentation. Also, I think it would be wonderful if Cloudmin has this option in a future release.

Jamie I think it would be awesome if CloudMin could make use of iSCSI LUN's from a SAN to provision Virtual Machines on the LUN's.

And, ideally, it would be great if CloudMin could automatically setup the iSCSI (if you give CloudMin the LUN login details for example) and setup cLVM or something similar on multiple Hypervisors for automatic Virtual Machine Failover. A further enhancement is if CloudMin could take 2 LUN's from 2 different SAN's and setup something similar to RAID1, and this mirror the Virtual Machines across the 2 SAN's. If one of the SAN's go offline, the VM's will still run on the other SAN. I believe this will give CloudMin a big edge over most of the other virtual machine management software (i.e. SolusVM, Proxmox, OnApp, etc) cavailable on the internet today

Agreed .. this is next on my TODO list, after IPv6 support (which is nearly done).

Hi Jamie,

Do you have an ETA on this by chance?

Hi Jamie,

Do you have an ETA on this?

P.S. Why do I get so many "500 internal server errors" when accessing the forum?

Sorry, this got pushed back to the next Cloudmin version .. so a few more weeks.

The 500 errors are due to load on our system, which will go away once we complete migration to a new server that Joe is setting up.
