Re: [Xen-users] LVM over Xen + Network

Very interesting. I was hoping that LVM2 could work with drives attached with other computers on the network.

In my organisation we've setup CLVM using a iSCSI shared storage backend to achieve this purpose. It works well, live migration works and speeds are good.

If using locally attached discs, the only way to have the data stored across the network is something like DRDB to perform raid1 network mirroring. However, you'll lose half your space and create a lot of network traffic in this approach.

Hi,

We are planning to have LVM being used over a network of 3 h/w machines(500 GB Disk each)
Each hardware machine will have 2-3 domUs.

Can we store these domUs as a Logical Volumes stored across Network of these 3 machines?

Can one DomU exceed the 500 GB (physical drive size) and store say 1 TB of data across the networked Physical Volumes?

Has anyone done this before?

Thanks and regards,
Rajan Chandi
