Re: [Xen-users] Windows DomU on NAS

Thanks for the tips guys!

So to recap, to expand the drive. I allocated more space to the Volume in Equallogic, did a logout and login on Dom0 of the iSCSI target. Restarted DomU and then used "Disk Management" to expand the C drive onto the new space. Worked great!

Now, I was also wondering about any performance or other issues there might be with using an iSCSI DomU?

You will need to run diskpart.exe in Windows to expand any filesystems once it sees the new size.

Equallogic is SAN storage, not NAS.

NAS == file storage (SMB, CIFS, NFS).
SAN == block storage (iSCSI, FC)

After resizing the Equallogic iSCSI LUN on dom0 you need to shutdown the domU and
reboot it to see the new size.

Then you need to possibly re-partition the disk on domU, then resize the
filesystem on the partition etc.
