What is the best way to move a running VM on the local machine to a SAN?(iscsi)

Thx,

And also, how do i seperate the SAN(Gbit) from the actual internet link(100Mbps) is there something what i have to keep in mind when doing that?

power off, backup and restore to the SAN.

Hi,

As far as I know, It is not possible to move VMs without shutting them down, when the disk is locally stored.

You can try (at your own risks) to rsync the running disk to your SAN (Don't forget the -s option if you have sparse files as disks), the to create a new VM with the new disk. Boot it, and if it works, try to rsync what have might changed between that time, and the first rsync. (typically /var, /home and /etc)

Keep us up to date if it works - or not !

Well i am trying to get a test setup by using openfiler.
I can get the proxmox server to see the iscsi disk, and create lvm but i cannot select it when creating a new kvm vm.

What am i doing wrong?

Hi,
you have select "Enabled" + Shared + Content Virtual Disk?
Post the content of /etc/pve/storage.cfg

Yes i have those enables.
But i can see in the cfg it is set to images...

dir: local
path /var/lib/vz
content images,iso,vztmpl,rootdir

lvm: vmDiskTest
vgname pve
content images

lvm: pp
vgname pve
shared
content images

iscsi: iii
portal 91.199.45.230
target iqn.2006-01.com.openfiler:tsn.555724e14933
content none

lvm: iii8
vgname pve
shared
content images

Hi,
why you use for all lvm-storages the underlaying pve (normaly the local volume group)?
Normaly you create a volumegroup on an external storage (iSCSI, FC) like "iscsi1-vg".
Then should the entry in storage.cfg looks like this:

lvm: iscsi1
vgname iscsi1-vg
shared
contend images

With this entry you should be able to select iscsi1 for a kvm-disk.
