Use SAN to create shared storage.

[gutter007]

I currently have two servers hooked up to a SAN. Here is my storage configuration.

dir: local
    path /var/lib/vz
    content images,iso,vztmpl,rootdir
    maxfiles 0

iscsi: dii_san1_md3200
    target iqn.1984-05.com.dell:powervault.md3200i.690b11c0000ce47900000000508ea061
    portal 192.168.130.101
    content none

lvm: dii_san1_lun0
    vgname dii_san1_lun0
    base dii_san1_md3200:0.0.0.scsi-dii_lun1
    shared
    content images

lvm: dii_san1_lun1
    vgname dii_san1_lun1
    base dii_san1_md3200:0.0.1.scsi-dii_lun2
    shared
    content images

I have multiple kvms running, and I'm able to live migrate and everything. I'm very happy with the setup.

We would like to also use a section of the SAN as a shared storage drive, the individual vms could connect to directly. The thought is that many of our servers could connect to it, similar to an nfs share, but hopefully faster.

Is this a bad idea?, and if not, what would be the best way to configure it?

thanks.

Does your MD3200 have a Hard Drive Filler?

Does your MD3200 have a Hard Drive Filler?

If you mean empty hard drive slots in the SAN, then yes, we have 6 open slots.

Sorry, I was confused. It seems MD3200 is an iSCSI SAN only so no filler functionality over NFS or CIFS. Then your best option, and which is also supported in Proxmox, is to create a GFS shared storage ontop off either a direct LUN or ontop LVM over LUN's. Choose direct LUN for speed and LVM for flexibility.
