[one-users] opennebula 3.4 LVM

[Nicolas AGIUS]

Hi,



I've rewrote and improved the TM LVM for one 3.4. It's designed to work 
with filesystem datastore on the frontend and LVM storage on the host. Support for cLVM between hosts will come soon.

I've also added some functionnalty, to save space on the frontend and speed up transferts. It can handle raw image (as usual), gzipped images and tgz filesystem (usefull when using XEN paravirt).



See patch at http://dev.opennebula.org/issues/1240

Hello,

actually in OpenNebula 3.4 the TM LVM drivers have been superseeded by
the iSCSI drivers. Today we removed the tm_lvm folder from the source,
but it's possible that we will bring them back for the final release.

However, the iSCSI drivers are a starting point for integrators to
develop their own TM drivers. The iSCSI commands can be nicely
substitued with specific SAN commands. Our initial idea is that
integrators will hack the iSCSI drivers to fit their san solutions
thus eliminating the dependency on CLVM.

So I encourage you to take a look at the TM iSCSI drivers and see if
it works with some adaption and hacking with your SAN.

Cheers,
Jaime
